Deep Wide View of Orion Constellation Immersed in a Giant Reddish Cloud of Hydrogen
The image features an HaRGB deep wide view of Orion Constellation immersed in the reddish hues from hydrogen alpha emission, where the larger semi-circle (Sh2-276) that stands around the belt and sword of Orion, also known as Barnard’s Loop, is shiningly visible like a dense intricate wave across the scene. Located at a distance of 1600 light-years away, the entire loop spans at about 300 light-years across in space and belongs to an even bigger Molecular Cloud of dust and gas, made up of molecular hydrogen and helium. These clouds are the birth place for stars, forming out of the material in the cloud. I always wanted to make an image like that showing all the beautiful reddish hydrogen that is surrounding one of the most spectacular and colourful regions of the entire night sky as seen from Earth, comprising known wonders like M42, Horse Head, LDN 1622, the large Lambda Orionis Ring and the bluish (OIII) Witch Head Nebula, close to Rigel star. As I only had the particular setup (Samyang 35mm f1.8 with Poseidon C Pro) available and prepared for this target two months before Orion constellation starts to set early against the western horizon and weather was not collaborating too, Orion was almost setting from our Observatory at Dark Sky® Alqueva, Portugal, which made a bit challenging to get this image done. Basically I only had 40 minutes of available sky for each clear night between February and March 2025, so to collecting 7h of good data it took me several nights which I could do it in one single night if it was done in the beginning of Winter. But here it is and I hope you enjoy the result.
PT: A imagem revela um campo amplo e profundo de HaRGB imerso nos tons avermelhados da emissão hidrogénio-alfa, onde parte do semicírculo maior (Sh2-276) que fica ao redor do cinturão e da espada de Orion, também conhecido como Loop de Barnard, é visível brilhando como uma onda densa e intrincada que atravessa toda a imagem. Localizado a uma distância de 1.600 anos-luz de distância, todo o Loop se estende por cerca de 300 anos-luz de diâmetro no espaço e pertence a uma Nuvem Molecular ainda maior de poeira e gás, composta de hidrogénio molecular e hélio. Estas nuvens são o local de nascimento de estrelas, formando-se a partir do material presente na nuvem. Desde há muito tempo que sonhei em captar uma imagem como esta, mostrando todo incrível hidrogénio avermelhado que envolve uma das regiões mais espetaculares e coloridas de todo o céu noturno, visto a partir da Terra, abrangendo algumas pérolas celestes bem conhecidas do grande público como a M42, Cabeça de Cavalo, LDN 1622, o grande Anel Lambda Orionis e a nebulosa azulada (OIII) Cabeça de Bruxa, situada junto à estrela Rigel. Como só tinha a configuração específica que usei (Samyang 35mm f1.8 com a Poseidon C-Pro) disponível e preparada para este alvo dois meses antes da constelação de Orion começar a pôr-se no horizonte Oeste e o bom tempo não colaborou muito, Orion já estava quase a pôr-se a partir do nosso Observatório no Dark Sky® Alqueva, Portugal, o que tornou um pouco desafiante fazer esta imagem. Basicamente, só tive 40 minutos de céu disponível para cada noite limpa entre Fevereiro e Março de 2025. Assim, para recolher 7 horas de dados, demorei várias noites, o que conseguiria fazer numa única noite se a imagem tivesse sido feito no início do Inverno. Mas aqui fica o resultado e espero que gostem!

M31 Immersed in Cosmic Clouds of Glowing Ionized Hydrogen in a Colorful Starry Scene
5 Years after my first attempt of capturing Andromeda galaxy surrounded by faint Ha clouds taken with a DSLR camera back in 2020, and inspired by the recent discover by STROTTNER-DRECHSLER-SAINTY of the OIII emission arc, I decided to get back to M31 and try my Luck. The image features a long integration of around 80h in HaOIII emission using a dual band filter, to show the colorful field of faint glowing ionized hydrogen gas where the galaxy seems to be immersed in. Despite these faint clouds, all the galaxy shape has a strong emission visible with Ha 3nm filter. The large-scale clouds formations visible in the foreground, belongs to our own Milky Way as well as the several distinct colorful stars which surrounds the diffuse spiral shape. While its spiral arms stand out in visible light, the arms look like rings in the GALEX ultraviolet views. Being sites of intense star formation, the rings have been interpreted as evidence that Andromeda collided with its smaller neighbouring elliptical galaxy M32 more than 200 million years ago. Even with all my efforts and challenges along the way, 80h where not enough to achieve the demanding level of good data needed for revealing the faint OIII arc, specially difficult in OSC cameras, so after analysing the data with the help of my experienced friend Yann Saint, I took the decision of not include the OIII data on the arc for being insufficient to reveal the proper expected shape and detail. Still, the OIII signal included and visible in the arms of M31 could reveals dozens of planetary nebulae. With approximately 220,000 light-years across, Andromeda is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum galaxy, and about 30 other smaller galaxies. I also decided to present my final view of M31 in a little different way, framing with a rotation that could help conducts our attention to the most interesting parts of the immersive hydrogen scene, keeping in mind to preserve the natural level of brightness on the core, giving a final nice light flow. So I hope you enjoy my result. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal.
PT: 5 anos após a minha primeira tentativa de captar a galáxia de Andrómeda rodeada por nuvens fracas de H-alfa, captada ainda com uma câmara DSLR no ano de 2020, e agora inspirada pela recente descoberta de STROTTNER-DRECHSLER-SAINTY do Arco de emissão OIII, decidi assim voltar a forografar a M31. A imagem apresenta uma longa integração de cerca de 80h na emissão HaOIII usando um filtro de banda dupla, para mostrar o campo colorido de gás hidrogénio ionizado brilhante e ténue, onde a galáxia parece estar imersa. Apesar destas nuvens ténues toda a galáxia tem uma forte emissão visível com filtro Ha 3nm. As formações de nuvens vermelhas de grande escala visíveis em primeiro plano, pertencem à nossa Via Láctea, bem como as várias estrelas coloridas distintas que rodeiam a forma espiral difusa. Embora os seus braços espirais se destaquem na luz visível, os braços parecem anéis nas imagens ultravioleta do GALEX. Sendo locais de intensa formação estelar, os anéis foram interpretados como evidência de que Andrómeda colidiu com a sua galáxia elíptica vizinha mais pequena, M32, há mais de 200 milhões de anos. Mesmo com todos os meus esforços e desafios ao longo do caminho, 80h não foram suficientes para atingir o nível exigente de informação que permitisse revelar o fraco arco OIII, especialmente difícil em câmaras OSC. Pelo que após analisar os dados com a ajuda do meu experiente amigo Yann Saint, tomei a decisão de não incluir o sinal OIII relativo ao arco por ser insuficiente para revelar a forma expectável e os detalhes que pretendia. Ainda assim, o sinal OIII incluído e visível nos braços da M31 permitiu revelar dezenas de nebulosas planetárias. Com aproximadamente 220.000 anos-luz de diâmetro, Andrómeda é a maior galáxia do Grupo Local, que contém também a Via Láctea, a galáxia do Triângulo e cerca de 30 outras galáxias mais pequenas. Por fim, decidi apresentar a minha visão final da M31 de uma forma ligeiramente diferente, enquadrando-a com uma rotação que premitisse ajudar a direcionar a nossa atenção para as partes mais interessantes neste cenário imersivo de hidrogénio, tendo em mente preservar o nível natural de brilho no núcleo, dando um fluxo de luz mais charmoso e suave. Espero que gostem! A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Reguengos, Portugal.

Bluish Planetary Nebulae HFG1 and Abell 6 Immersed in a Glowing Field of Hydrogen Gas
Captured in HaOIII and RGB light, the image features a deep wide field view immersed in the glow of ionized hydrogen gas, where small planetary nebulae Abell 6 and larger HFG1 (Heckathorn-Fesen-Gull 1 nebula type) seems to live, in the constellation of Cassiopeia. Being both remnants from the last phase of a medium star like our Sun. HFG1 features a bluish arc shaped shock wave, created by the binary star system V664 Cas, which comprises a white dwarf and a red giant star only a few million kilometres apart from each other. The small bright bluish ball visible near the center of the image, is known as Abell 6. Those kind of planetary nebulae, has a short life span of only about 10,000 years, becoming then invisible due to a lack of ultraviolet light emitted by the stars that create them. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal.
PT: Captada em diferentes comprimentos de onda entre a luz Ha, OIII e RGB, a imagem apresenta uma visão ampla e profunda, imersa no brilho do gás hidrogénio ionizado, onde a pequena nebulosa planetárias Abell 6 e a mais extensa HFG1 (nebulosa planetária de tipo: Heckathorn-Fesen-Gull 1) parecem viver, na constelação de Cassiopeia. Sendo ambos remanescentes da última fase de uma estrela média como o nosso Sol. HFG1 apresenta uma onda de choque em forma de arco azulado, criada pelo sistema estelar binário V664 Cas, que compreende uma anã branca e uma estrela gigante vermelha, orbitando a apenas alguns milhões de quilómetros de distância uma da outra. A pequena bola azulada brilhante visível perto do centro da imagem, é conhecida como Abell 6. Este tipo de nebulosa planetária tem uma vida curta de apenas cerca de 10.000 anos, tornando-se então invisível devido à falta de luz ultravioleta emitida pelas estrelas que as criaram. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal.

Comet C/2023 A3 Tsuchinshan-Atlas Shining in All Its Glory
Finally I got time to process my close-up image taken from Dark Sky® Alqueva with 300mm prime lens f2.8, on 13th October, when C/2023 A3 Tsuchinshan-Atlas was revealing an impressive level of brightness and details, as well as a cool anti-tail frontal spike. It seems that the ion tail is also visible and a prominent dust tail. I processed this one with my deepsky techniques to recover as much as possible the original color and details hidden in the dust tail, washed out, easily, due to the bluish background scattered light from Moon and Twilight. 75 short exposures of 10 seconds at ISO1600, comprising around 12 minutes of images.

Parece que a cauda de iões também se tornou visível aliada a uma cauda de poeira bastante proeminente. Processei esta imagem com as minhas técnicas de deepsky para recuperar o mais possível a cor original e os detalhes escondidos na cauda de poeira, facilmente ocultada, devido ao fundo azulado causado pela dispersão da luz da Lua e do crepúsculo. 75 exposições curtas de 10 segundos a ISO1600, compreendendo cerca de 12 minutos de imagens.

Massive Clouds of Hydrogen Gas Glowing in Cepheus Revealed in a Deep Wide Scene
The deep wide field scene shows in Ha and OIII emission, the large complexity of bright and dark nebulosity located in Cepheus constellation. The view is amazing revealing a tremendous amount of hydrogen gas in a large field of view, comprising dozens of well know nebulae such as the large bright cloud where is located the Elephant’s Trunk Nebula IC1396, up to the opposite edge where is visible Lobster Claw Nebula SH2-157. It’s also Incredible to compare the differences in angular size between some of these objects that we are used to see in close-up images, such as the bright shell of Flying Bat with the embedded blueish Squid Nebula or the the Lion Nebula Sh2-132 Immersed in a glowing field of ionised hydrogen and oxygen gas (Ha and OIII emission). At the end is available the annotated detailed version containing the main objects visible in the image. Captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal.

The Lion Nebula Sh2-132 Immersed in a Glowing Field of Hydrogen Gas
Captured in HaOIII and RGB light, the image features a deep wide field view of Sh2-132 immersed in the glow of ionized hydrogen gas. Also known as the Lion Nebula, it is located at about 10,000 light years away in the Cepheus constellation. Formed from expanded shells of ionized gas, the nebula is powered by two massive stars, each with a mass over 20 times greater than our Sun.The nebula’s energetic matter is dense enough to contract gravitationally and form stars. One side is more predominant of reddish hues from Ha emission, while the other one is more predominant of blusish hues from ionized Oxygen in OIII emission. The wide field view covering a little bit more than the angular size of the full moon can also comprise small planetary nebulas, like PK104-01.1; PK104-01.2 or the 1.0 arc minute small planetary nebula Abell 79. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal, with the New ZEUS 455C Pro. from Player One Astronomy.
PT: Captada em diferentes comprimentos de onda entre a luz Ha, OIII e RGB, a imagem apresenta uma visão ampla de Sh2-132, um objecto de céu profundo imerso no brilho do gás hidrogénio ionizado. Também conhecida como Nebulosa do Leão, está localizada a cerca de 10.000 anos-luz de distância, na constelação de Cefeu. Formada a partir de “conchas expandidas” de gás ionizado, a nebulosa é alimentada por duas estrelas massivas, cada uma com uma massa 20 vezes superior à do nosso Sol. A matéria energética da nebulosa é suficientemente densa para se contrair gravitacionalmente e formar estrelas. Um dos lados é mais predominante nos tons avermelhados provenientes da emissão de Ha, enquanto o outro lado é mais predominante nos tons azulados relativos ao Oxigénio ionizado, na emissão de OIII. A imagem cobre um pouco mais do que o tamanho angular da lua cheia, incluindo assim no seu campo de visão, pequenas nebulosas planetárias, como: PK104-01.1; PK104-01.2 ou a pequena nebulosa planetária Abell 79, com apenas 1 minuto de arco. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal, com uma câmara Player One Astronomy, a nova ZEUS 455C Pro.

WR 134 Wolf-Rayet Star Immersed in a Colorful Complex of Hydrogen and Oxygen Gas
Captured in HaOIII and RGB light, the image features a deep wide field view of WR 134, a variable Wolf-Rayet star located around 6,000 light years away from our planet Earth in the constellation of Cygnus, which is surrounded by a faint bubble nebula traced by the glow of ionized hydrogen and oxygen gas, blown by the intense radiation and fast wind from the star. WR 134 is less than a degree away from WR 135. Both stars lie within a shell of hydrogen thought to have been swept up from the interstellar medium when one or both stars were on the main sequence. The greenish shell is over forty parsecs wide and contains about 1,830 times, the solar mass, of hydrogen. It is unclear which of the two stars is primarily responsible for creating the shell. The nebula seems to be immersed in a much larger complex cloud full of reddish hydrogen and greenish oxygen gas and among them, we can see dozens of interesting objects such as small planetary nebulas Ou6, Pa143, MoMi6, StDr109 and a few filaments from Super Nova Remnant, such as SNR G73.9+0.9 and SNR G749.9+1.2. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal, with the New ZEUS 455C Pro. from Player One Astronomy.
PT: Captada em comprimentos de onda diferentes entre a luz Ha, OIII e RGB, a imagem apresenta uma amplo campo de céu profundo da WR 134, uma estrela Wolf-Rayet variável localizada a cerca de 6.000 anos-luz de distância do nosso planeta Terra na constelação do Cisne, que é cercada por uma ténue nebulosa esverdeada em forma de bolha traçada pelo brilho do hidrogénio ionizado e gás oxigénio, soprado pela radiação intensa e vento rápido da estrela central. WR 134 está a menos de um grau de distância da WR 135. Ambas as estrelas estão dentro de uma camada de hidrogénio que se acredita ter sido varrida do meio interestelar quando uma, ou ambas as estrelas estavam na sequência principal. A camada esverdeada tem mais de quarenta parsecs de largura e contém cerca de 1.830 vezes a massa solar de gás hidrogénio. Não está claro qual das duas estrelas é a principal responsável pela criação da camada. A nebulosa parece estar imersa em uma nuvem complexa muito maior, cheia de hidrogénio avermelhado e gás oxigénio esverdeado e entre eles, podemos ver dezenas de objetos interessantes, como pequenas nebulosas planetárias Ou6, Pa143, MoMi6, StDr109 e alguns filamentos de Super Nova Remanescente, como SNR G73.9+0.9 e SNR G749.9+1.2.

Massive Clouds of Hydrogen Gas Glowing Along Cygnus Constellation in a Deep Wide Scene
The deep wide field scene is a mosaic of 6 panels showing in Ha and OIII emission, the large complexity of bright and dark nebulosity located along the path of Cygnus constellation (the Swan). The view is mesmerising revealing a tremendous amount of hydrogen gas with intricate filaments of large and small scale, comprising dozens of well know nebulae such as the giant NGC 7000 (North America Nebula) and IC 5070, (Pelican Nebula). It’s also Incredible to compare the differences in angular size between some of this objects, being NGC 6888, the Crescent Nebula, visible in the right centre, as a suspended small bright shell. In the lower right corner, NGC 6990 and NGC 6992, the Veil Nebula, shines bright in red and greenish hues – Ha and OIII emission – as the remains of a supernova explosion. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal.
PT: Este campo amplo e profundo é um mosaico de 6 painéis revelando no comprimento de onda Ha (hidrogénio) e OIII (oxigénio), a grande complexidade de nebulosidade brilhante e escura localizada ao longo do caminho da constelação Cygnus (o Cisne). A visão é hipnotizante, revelando uma tremenda quantidade de gás hidrogénio-alfa com filamentos intrincados de grande e pequena escala, contendo dezenas de nebulosas bem conhecidas, como a grande nebulosa NGC 7000 (Nebulosa América do Norte) e IC 5070 (Nebulosa Pelicano). É também incrível de notar e comparar, as diferenças no tamanho angular entre alguns desses objetos, sendo NGC 6888, a Nebulosa Crescente, visível no centro direito como uma pequena concha brilhante suspensa. No canto inferior direito, NGC 6990 e NGC 6992, a Nebulosa do Véu, brilha intensamente em tons vermelhos e esverdeados – emissão Ha e OIII – como os restos mortais de uma explosão supernova. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal.

Celestial duet Between Comet 12P/Pons-Brooks and Andromeda Galaxy M31
A wide field view of the winter sky shows a celestial duet between Comet 12P/Pons-Brooks and Andromeda Galaxy M31. The comet was crossing close to the galaxy on March 11, 2024. It was a challenging image as the comet was too low, close to the horizon and I only had 28 minutes to collect as much photons as possible. The image was taken from Dark Sky® Alqueva region, in São Lourenço do Barrocal, Portugal, with a 70-200mm lens set to 120mm.

A Reddish Portrait from Barnard’s Loop with Boogeyman Dark Nebula and M78
The image features an HaRGB wide deep sky portrait immersed in the reddish hues from hydrogen alpha emission, where part of the larger semi-circle (Sh2-276) that stands around the belt and sword of Orion, also known as Barnard’s Loop, is shiningly visible like a dense intricate wave across the scene. Located at a distance of 1600 light-years away, the entire loop spans at about 300 light-years across in space and belongs to an even bigger Molecular Cloud of dust and gas, made up of molecular hydrogen and helium. These clouds are the birth place for stars, forming out of the material in the cloud. Above the “reddish loop” and near the top edge of the image, is possible to enjoy LDN 1622, a large dark nebula also known as Boogeyman, located at 500 light-years away. Below the center wave are visible two reflection nebulas M78 and NGC 2071. M78 lies at approximately the same distance as Barnard’s Loop but it only spans 5 light-years in space. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal.
PT: A imagem revela um campo amplo e profundo de HaRGB imerso nos tons avermelhados da emissão hidrogénio-alfa, onde parte do semicírculo maior (Sh2-276) que fica ao redor do cinturão e da espada de Orion, também conhecido como Loop de Barnard, é visível brilhando como uma onda densa e intrincada que atravessa toda a imagem. Localizado a uma distância de 1.600 anos-luz de distância, todo o Loop se estende por cerca de 300 anos-luz de diâmetro no espaço e pertence a uma Nuvem Molecular ainda maior de poeira e gás, composta de hidrogénio molecular e hélio. Essas nuvens são o local de nascimento das estrelas, formadas a partir do material da nuvem. Acima do “Loop avermelhado” e próximo ao extremo superior da imagem, é possível apreciar LDN 1622, uma grande nebulosa escura também conhecida como Boogeyman, localizada a 500 anos-luz de distância. Abaixo da onda central são visíveis duas nebulosas azuladas de reflexão M78 e NGC 2071. M78 fica aproximadamente à mesma distância do Loop de Barnard, mas se estende por apenas 5 anos-luz no espaço. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal.

The Veil Nebula Supernova Remnant With Shining Filaments of Glowing Ionized Gas
The Veil Nebula, also known as the Cygnus Loop, is the result of a supernova remnant located toward the constellation of Cygnus at about 1,400 light-years away. The nebula was created between 5,000 to 15,000 years ago, after a cataclysmic explosion of a massive star. The interstellar shock wave was projected through space exciting interstellar material. The entire Veil Nebula spans 6 times the diameter of the full Moon which is equivalent to 70 light-years across and is still expanding into space. The nebula reveals these tangled filaments of glowing ionized gas. Ripples remarkably well separated into reddish hues from atomic hydrogen gas and blue-greenish hues from atomic oxygen gas. This deep space scene also includes the Witch’s Broom Nebula (NGC 6960) where bright 52 Cygni star is shining, and the Fleming’s Triangular Wisp (NGC6979) as well as NGC6974. The Veil Nebula was discovered by William Herschel on September 5, 1784. The image captured from Dark Sky® Alqueva observatory, in different wavelengths between Ha, OIII and RGB light, using the Anit-Halo PRO Dual-Band 3nm and a Poseidon-C Pro Camera from Player One Astronomy.
PT: A Nebulosa do Véu, também conhecida como Cygnus Loop, é o resultado de uma supernova remanescente localizada próximo à constelação do Cisne, a cerca de 1.400 anos-luz de distância. A nebulosa foi criada entre 5.000 a 15.000 anos atrás, após a explosão cataclísmica de uma estrela massiva. A onda de choque interestelar foi projectada através do espaço, excitando material interestelar. Toda a Nebulosa do Véu mede 6 vezes o diâmetro da Lua cheia, o que equivale a 70 anos-luz de extensão e ainda se continua a expandir para o espaço actualmente. A nebulosa revela filamentos emaranhados de gás ionizado brilhante. Ondulações notavelmente bem separadas em tons avermelhados provenientes do gás hidrogénio atómico e tons de azul-esverdeado do gás oxigénio atómico. Este retrato amplo do espaço profundo também inclui a Witch’s Broom Nebula (NGC 6960), onde se encontra a estrela brilhante 52 Cygni, e Fleming’s Triangular Wisp (NGC6979), bem como NGC6974. A Nebulosa do Véu foi descoberta por William Herschel em 5 de setembro de 1784.

The Great Dragon of Pelican Nebula in All Its Glory
The image features a dark region between Pelican Nebula and the Cygnus Wall. This region is very often photographed specially because the well know North America nebula NGC7000 where this region of the sky is embedded, but many few images – I only found half a dozen in Astrobin until today, making some reference – are showing the real portrait of the “hidden” Dragon in all its glory, which I tried to emphasise in my framing and personally would like to named the Great Dragon of Pelican. The dark nebula LDN 935 which represents the figure shape of a Chinese Dragon, is known as the “Gulf of Mexico” – more easy to understand if seeing it in a different angle – is a region where the obscured interstellar dust lanes are absorbing and scattering the light, darkening the region between both nebulas. The greenish right edge reveals the bright interesting area known as the Cygnus Wall, a true stellar nursery of newly formed stars. The wall is eroded and illuminated by bright young stars, partially not visible for being occulted behind the dust they have just created. On the left side of the dust, is shining the Pelican Nebula, a star formation and evolving cloud of gas. The light from young energetic stars is slowly transforming the cold gas into hot gas, revealing the advancing boundary between both, known as the ionization front, and visible on the image as the bright orange-reddish region, with intricate filaments of cold gas visible along the front. The image captured from Dark Sky® Alqueva observatory, in different wavelengths between Ha, OIII and RGB light, using the Anit-Halo PRO Dual-Band 3nm and a Poseidon-C Pro Camera from Player One Astronomy.
PT: A imagem mostra uma região escura entre a Nebulosa do Pelicano e a Parede do Cisne. Esta região é frequentemente fotografada especialmente por causa da conhecida nebulosa North America NGC7000 onde esta região do céu está embutida, mas muito poucas imagens – só encontrei meia dúzia até hoje no Astrobin com algum tipo de referência – mostram o retrato real do Dragão “oculto” em toda a sua glória, que tentei enfatizar neste meu enquadramento e pessoalmente apelidei de o Grande Dragão do Pelicano. A nebulosa escura LDN 935, que representa a figura do Dragão chinês, é na verdade conhecida como “Golfo do México” – mais fácil de entender se vista de um ângulo diferente – é uma região onde as faixas obscuras de poeira interestelar estão absorvendo e espalhando a luz, escurecendo a região entre as duas nebulosas. A zona esverdeada à direita revela uma área brilhante e interessante conhecida como Parede do Cisne, um verdadeiro berçário de estrelas recém-formadas. A parede está erodida e iluminada por estrelas jovens e brilhantes, parcialmente invisíveis por estarem ocultas atrás da poeira que acabaram de criar. No lado esquerdo da poeira escura do Dragão, brilha a Nebulosa do Pelicano, uma formação estelar e uma nuvem de gás em evolução. A luz de estrelas jovens e energéticas está lentamente transformando o gás frio em gás quente, revelando a fronteira avançada entre ambos, conhecida como frente de ionização, e visível na imagem como a região laranja-avermelhada brilhante no centro inferior esquerdo, com intrincados filamentos de gás frio visíveis ao longo da frente como pequenos pilares. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal, em diferentes comprimentos de onda entre a luz Ha, OIII e RGB e usando o filtro Anit-Halo PRO Dual-Band 3nm, conjuntamente com a Poseidon-C Pro Camera, da Player One Astronomy.

Comet C/2023 E1 Atlas In a Rare Encounter with Flying Bat and Squid Nebula
A deepsky wide portrait captured in different wavelengths between Ha, OIII and RGB light, features a large reddish cloud of glowing hydrogen gas from the Sh2-129, known as Flying Bat nebula with a physical diameter of 271 light-years, seems to have embedded a blueish giant Squid which spans across the center 50 light-years long. Discovered in 2011 by French astrophotographer Nicolas Outters, and located in the constellation Cepheus, the very faint bipolar shape from this planetary nebula (stars like our sun transform themselves into white dwarfs by casting off their outer gaseous) is distinguished here by the blue-green emission from doubly ionized oxygen atoms. Although, an extra greenish diffuse ball is visible close to the edge of Flying Bat reddish wings, it’s not a new type of fancy nebulas, but a rare encounter with a solar system visitant, the lonely faint comet C/2023 E1 Atlas, shinning with a dimmer 14.7 magnitude, its orbiting the Sun every 85 years at an average distance of 19 AU. Among the 11 nights between July and August that I spent shooting the Flying Bat nebula to acumulate the total time exposure of 39.5 hours, I had a great luck for being capturing on the night of 5 August 2023 around UT23h, and using the Anit-Halo PRO Dual-Band 3nm from Player One. Because I was able to capture Ha and OIII at the same time, allowing the green coma of the comet to turn visible in my filtered light for being emitting in the same wavelength where OIII emission lies in the G and B channels. If it was only Ha, I would miss it because it was totally invisible in this narrowband red channel. Close to the left edge, are lying nebulas VdB 140 and LDN 446. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal, with a Poseidon-C Pro Camera.
PT: Um retrato amplo do céu profundo captado em comprimentos de onda diferentes entre a luz Ha, OIII e RGB, apresenta uma grande nuvem avermelhada de gás hidrogénio brilhante a Sh2-129, conhecida como nebulosa do Morcego Voador (Flying Bat Nebula) com um diâmetro físico de 271 anos-luz, parece ter incorporado uma lula gigante azulada que se estende pelo centro por 50 anos-luz de comprimento. Descoberta em 2011 pelo astrofotógrafo francês Nicolas Outters, e localizada na constelação de Cepheus, a forma bipolar muito ténue desta nebulosa planetária (estrelas como o nosso Sol transformam-se em anãs brancas ao libertarem o seu gás exterior) distingue-se aqui pelo azul esverdeado resultado da emissão de átomos de oxigénio duplamente ionizados. A imagem revela ainda uma estranha bola difusa esverdeada, visível perto das asas avermelhadas da nebulosa do Morcego Voador, não é um novo tipo de nebulosa fancy, mas um raro encontro com um visitante do sistema solar. O tímido cometa solitário C/2023 E1 Atlas, brilha com uma fraca magnitude de 14.7, orbitando o Sol a cada 85 anos a uma distância média de 19 UA (1 Unidade Astronómica – é o equivalente da distância entre a Terra e o Sol). Das 11 noites entre Julho e Agosto que dediquei à captação da nebulosa Flying Bat para acumular o tempo total de exposição de 39.5 horas, tive a sorte por uma destas ter sido a noite de 5 de Agosto de 2023 por volta das 23h UT, e por estar a usar o filtro Anit-Halo PRO Dual-Band 3nm da Player One. Isto porque consegui captar Ha e OIII ao mesmo tempo, permitindo que o Coma verde do cometa ficasse visível na minha luz filtrada por estar emitindo no mesmo comprimento de onda, onde recai a emissão de OIII, apenas visível nos canais verde (G) e azul (B). Se fosse apenas Ha, eu teria perdido esta passagem do cometa porque era totalmente invisível neste canal vermelho de banda estreita (R). Perto do extremo esquerdo da imagem, encontram-se ainda as nebuloas VdB 140 e LDN 446. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal, com uma Player One Astronomy, a Poseidon-C Pro Camera.
Below: The annotated version produced with PixInsight script, based in several known catalogues to identify the main objects in the image, as well as the image without the presence of the comet to appreciate only the nebulas and starfield presented in landscape and portrait, intended to help conduct the reader attention to the most interesting parts of the image. At Last, a quick video animation of the transit over 30 raw inidividual calilbrated frames, taken with Green and Blue channel extracted from the OIII and lighten up with low opacity of the Red Ha channel to reveal an hint of the Flying Bat shape.

IC 410 and IC 405 Shines in a Colorful Deepsky Portrait of HaOIII and RGB Light
A deepsky wide portrait captured in different wavelengths between Ha, OIII and RGB light, features two large emission nebulae complexes lying in the constellation of Auriga. At left (or up on the portrait version), IC410 also known as Tadpole Nebula, located at about 12,000 light-years away, is a cloud of glowing gas with 100 light-years across, sculpted by stellar winds and radiation from embedded open cluster NGC 1893, shinning near the dark dense cloud at the center of the star-forming nebula. Not faraway, two dense streamers of material can be noticed, trailing away from the nebula’s central regions. These cosmic tadpole, are potentially sites of ongoing star formation with about 10 light-years long. Bright colorful stars from Auriga constellation are shining in the center of this cosmic portrait, between the two main large nebulas. Visible on the right side of the landscape version (below on the portrait one), The Flaming Star nebula, IC 405, lies at about 1,500 light-years away. Glowing in red, convoluted clouds of hydrogen and filaments of atomic gas, are energized by hot, young variable O-type star AE Aurigae, which illuminates the nebula while its blue starlight is scattered by interstellar dust. While retracing the star’s motion through space, astronomers have conclude that AE Aurigae is a blue runaway star that is believed to have been ejected from the Orion nebula some 2.7 million years ago. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal, with a Poseidon-C Pro Camera from Player One Astronomy, and the new Anit-Halo PRO Dual-Band (Ha+OIII) 3nm.
PT: Um retrato amplo do céu profundo captado em comprimentos de onda diferentes entre a luz Ha, OIII e RGB, apresenta dois grandes complexos de nebulosas de emissão, situados na constelação de Auriga. À esquerda (ou acima na versão retrato), IC410, também conhecida como Nebulosa do Girino, localizada a cerca de 12.000 anos-luz de distância, é uma nuvem de gás brilhante com 100 anos-luz de diâmetro, esculpida por ventos estelares e radiação de um aglomerado aberto embutido na nebulosa, NGC 1893, que brilha perto da nuvem escura e densa no centro desta nebulosa de formação estelar. Não muito longe, podem ser observadas duas densas correntes de material, afastando-se das regiões centrais da nebulosa. Esses “girinos” cósmicos são potencialmente locais de formação estelar contínua com cerca de 10 anos-luz de comprimento. Estrelas coloridas e brilhantes da constelação de Auriga, destacam-se no centro deste retrato cósmico, separando as duas grandes nebulosas principais. Visível no lado direito da versão de paisagem (abaixo na versão retrato), a nebulosa Flaming Star, IC 405, fica a cerca de 1.500 anos-luz de distância. Brilhando em tons de vermelho, nuvens convolvidas de hidrogénio e filamentos de gás atómico são energizadas pela jovem e quente estrela variável do tipo-O, AE Aurigae, que ilumina assim a nebulosa enquanto a sua luz estelar azul é espalhada pela poeira interestelar. Ao retraçar o movimento da estrela através do espaço, os astrónomos concluíram que AE Aurigae é uma estrela azul em fuga que se pensa ter sido ejectada da nebulosa de Orion há cerca de 2,7 milhões de anos. A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal, com uma Player One Astronomy, a Poseidon-C Pro Camera e novo filtro Anit-Halo PRO Dual-Band (Ha+OIII) 3nm.

The Crescent and Soap Bubble Nebula Shining in a Wide Scene from Ha and OIII Emission
The image shows an HaOIII wide field where NGC 6888 also known as the Crescent Nebula, seems to be immersed in. Even looking similar to a supernova remnant, The Crescent is indeed a relatively rare nebula that surrounds WR136 (HD 192163) a Wolf-Rayet dying star in the constellation of Cygnus. The gigantic bubble of gas it was formed by the stellar wind. The central star is releasing massive amounts of gas and UV irradiation, exciting oxygen and hydrogen to emit in the blue and red wavelength illuminating the nebula. The Wolf-Rayet star will probably end up exploding as a supernova within the next 100,000 years. Shinning against the background sculptured by a massive cloud of hydrogen from Cygnus region, is visible another small bubble, known as the the “Soap Bubble” a planetary nebula (PN G75.5+1.7) very faint visible in filtered OIII light. The image was captured from Dark Sky® Alqueva Observatory, Cumeada, in Portugal. This was also the “first light” from my new combo system from Player One Astronomy, the Poseidon-C Pro Camera and the new Anit-Halo PRO Dual-Band (Ha+OIII) 3nm filter and it works incredibly well!
PT: A imagem revela um campo amplo e profundo de HaOIII onde a NGC 6888, também conhecida como Nebulosa Crescente, parece estar imersa. Mesmo parecendo semelhante a uma supernova remanescente, a nebulosa Crescente é de facto uma nebulosa relativamente rara que circunda a WR136 (HD 192163), uma estrela “moribunda” Wolf-Rayet na constelação do Cisne. A gigantesca bolha de gás foi formada pelo vento estelar. A estrela central vai assim libertando grandes quantidades de gás e radiação UV, estimulando a emissão de oxigénio e hidrogénio no comprimento de onda azul e vermelho, que ilumina assim a nebulosa. A estrela Wolf-Rayet provavelmente acabará explodindo como uma supernova nos próximos 100 mil anos. Brilhando contra o fundo esculpido por uma enorme nuvem de hidrogénio da região do Cisne, é visível outra pequena bolha, conhecida como a “Bolha de Sabão”, uma nebulosa planetária (PN G75.5+1.7) muito fraca, visível na luz filtrada OIII (Oxigénio). A imagem foi captada a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, Portugal. Esta foi também a chamada “first light” do meu novo sistema substituto da DSLR, um combo perfeito da Player One Astronomy, a Poseidon-C Pro Camera e novo filtro Anit-Halo PRO Dual-Band (Ha+OIII) 3nm que se revelou verdadeiramente incrível!

Rare View of Markarian’s Chain Immersed in the Reddish Hydrogen Gas of Virgo Cluster
The image features a deep wide-field scene captured at 530mm and comprising 76,5h of total integration exposure (18,5h in RGB + 58h in Ha), showing galaxies at a distance of 48 million light-years away from Earth, where lies the Virgo Cluster. This collection of galaxies located in the constellation of Virgo, forms the heart of the larger Virgo Supercluster from which the Local Group containing our own Milky Way galaxy, belongs. It’s also known that our own Milky Way galaxy has clouds of hydrogen gas within, lying between us and the Virgo cluster. The image shows more 833 galaxies visible and identified in the annotated version below, and immersed in some of these hydrogen-alpha clouds, while mixed with the clouds contained in the cluster itself. This region is also know as Markarian’s Chain, which includes the gigantic elliptical galaxy M87, the enormous elliptical galaxy M86 and M84, as well as the colorful galaxy M88. The image was captured from Dark Sky® Alqueva Official Observatory, in Portugal, over the course of 17 nights between February and May 2023.

Comet ZTF and Mars Shinning close to Hyades and Pleiades Immersed in the Colorful Dusty Field of Taurus
A wide field view of the winter sky shows a duet of open clusters known as Hyades and Pleiades, involved in the faint dust from Taurus molecular cloud. Comet c/2022 E3 (ZTF) and planet Mars also joined the scene, while being visible in this region of the sky on February 13, 2023. The close-up image of Mars and Comet ZTF was taken from Dark Sky® Alqueva official osbervatory in Portugal, on this date with a 300mm lens and it was later rescaled and star aligned to perfectly match on the background deep field scene I had previously acquired and processed in 2020, which comprises 5h of long exposure integration taken from the same place with a 105mm lens to reveal the faintest dust of this colorful region of the winter sky. For that particular reason, the field unfortunately doesn’t cover entirely the area where is located planet Mars.

O cometa c/2022 E3 (ZTF) e o planeta Marte também entraram em cena, sendo visíveis nesta região do céu a 13 de Fevereiro de 2023. A imagem em close-up de Marte e do cometa ZTF foi captada nesta data a partir do Obervatório Oficial do Dark Sky® Alqueva, na Cumeada, com uma objectiva de 300 mm e posteriormente foi redimensionada e alinhada às estrelas para ser combinada com a imagem de fundo adquirida e processada previamente em 2020 a partir do mesmo local, e que compreende uma integração total de 5h de exposição, captadas com uma lente de 105 mm para assim poder revelar a poeira mais subtil e fraca dessa região colorida do céu de inverno. Por esse motivo particular, o campo infelizmente não cobre totalmente a área onde está localizado o planeta Marte.

A Last Charm of Comet ZTF While Reaching the Closest Point to our Planet Earth
The image shows a close-up view of Comet c/2022 E3 (ZTF) on January 31, 2023, just a few hours before it reach the maximum approach to our Planet Earth. Still featuring the wonderful greenish-blue coma from glowing carbon gas, the rare anti-tail is now pointing towards down due the actual position in the orbital plane. The comet is now showing almost a single distinct ion tail. This was perhaps my last image of this beauty due to the full moon presence acting as a natural source of light pollution and the fact that from now on, the comet it will decrease in brightness as is starts to fade way in a long journey of 50,000 years immersed in the deepest cold and darkness of the Solar System. This cosmic portrait also reveals dozens of galaxies surrounding the Comet dust. Captured late in the night at a distance of 43.1 million Km from Dark Sky® Alqueva Observatory in Portugal. ZTF was located in the constellation of Camelopardalis, showing a faint visual magnitude of +5.4.
PT: A imagem revela um close-up do Cometa c/2022 E3 (ZTF) na noite de 31 de janeiro de 2023, apenas a algumas horas antes de atingir a máxima aproximação ao Planeta Terra. Ainda exibindo um elegante coma azul-esverdeado proveniente do brilho do gás carbono, a rara anti-cauda está agora apontando na direcção inferior devido à sua posição no plano orbital. O cometa neste momento mostra quase uma única cauda distincta de iões. Esta foi talvez a minha última imagem desta beleza devido à presença da lua cheia actuando como uma fonte natural de poluição luminosa e ao facto de que a partir de agora, o cometa diminuirá gradualmente de brilho à medida que começa a desaparecer em uma longa jornada de 50.000 anos, onde irá imergir no mais profunda escuridão gélida do Sistema Solar. Este retrato cósmico também revela dezenas de galáxias em torno da poeira que circunda o Cometa. Captado no final da noite e a uma distância de 43,1 milhões de Km do Observatório Dark Sky® Alqueva em Portugal. ZTF estava localizado na constelação de Camelopardalis, mostrando uma fraca magnitude visual de +5,4.

Comet ZTF Featuring Two Ion Tails While Crossing in Front of a Galaxy in a Colorful Starfield
The image shows a close-up view of Comet c/2022 E3 (ZTF) during 24th January 2023. Besides the wonderful greenish coma from glowing carbon gas the image reveals a rare anti-tail due the fact that planet Earth was crossed the orbital plane of Comet ZTF showing the tail in perspective and immersed in a colorful starfield. One thing I noticed from the previews nights, is the low angle of the frontal tail compared to the images I made on 22th Janurary, as it now shows a slightly change in the angle. The comet if also featuring two distinct bluish ion tails and the white dust tail on the image, is crossing in front of a background galaxy. The comet was photographed late in the night at a distance of 59.8 million Km from Dark Sky® Alqueva Observatory in Portugal. This long distance traveller not seen in 50,000 years, is moving fast against the background starry sky, and that night it was located close to the star Edasich, from Draco constellation, showing a faint visual magnitude of +6.0. On 1st February the Comet it will be in the closest point to our planet and eventually until then, it could reach a naked eye magnitude.
PT: A imagem revela um close-up do Cometa c/2022 E3 (ZTF) durante a noite de 24 de Janeiro de 2023. Além de apresentar um maravilhoso coma esverdeada proveniente do brilho do gás carbono, a imagem revela uma rara anti-cauda devido ao facto do planeta Terra ter cruzado o plano orbital do Cometa ZTF mostrando assim a cauda em perspectiva e imersa em um campo estelar colorido. Um pormenor que notei em relação às noites anteriores, é o baixo ângulo da cauda frontal (anti-cauda) em comparação com as imagens que fiz na noite de 22 de Janeiro, pois agora mostra uma pequena mudança nesse ângulo. O cometa, também apresenta duas caudas de iões azuladas e distintas e a cauda de poeira branca, na imagem, esta a cruzar-se em frente a uma galáxia visível em pano de fundo. O cometa foi fotografado no final da noite a uma distância de 59.8 milhões de Km a partir do Observatório Dark Sky® Alqueva em Portugal. Este viajante longínquo que não se avistava há cerca de 50.000 anos, move-se muito rapidamente contra o fundo do céu estrelado, e naquela noite estava localizado próximo à constelação do Dragão, mostrando uma fraca magnitude visual de +6.0. A 1 de Fevereiro o cometa estará no ponto mais próximo do nosso planeta e eventualmente até então poderá atingir uma magnitude visível a olho nu .

Comet c/2022 E3 ZTF Featuring a Rare Anti-Tail During a Disconnection Event
The image shows a close-up view of Comet c/2022 E3 (ZTF) during 19th January 2023. Besides featuring a wonderful greenish coma from glowing carbon gas and rare anti-tail, something unusual was happening with the long ion tail, what is called a disconnection event. A piece of Comet ZTF’s tail has been disconnected and is being carried away by the solar wind. The comet was photographed late in the night at a distance of 79 million Km from Dark Sky® Alqueva Observatory in Portugal, three hours before starts the astronomical twilight. This long distance traveller not seen in 50,000 years, is moving fast against the background starry sky, and that night it was located between constellations of Hercules, Corona Borealis and Bootes, showing a faint visual magnitude of +6.6. Although on 1st February the Comet it will be in the closest point to our planet and eventually until then could reach a naked eye magnitude, but this kind of objects are pretty unpredictable and we never know what surprise is waiting for us.

Comet C/2022 E3 (ZTF) during Perihelion Revealing a Glowing Greenish Coma and Long Ion Tail
The image shows a close-up view of Comet c/2022 E3 (ZTF) during Perihelion, when it was close to the Sun, on 12th January 2023. Featuring a wonderful greenish coma from glowing carbon gas and a long ion tail by the ions ejected from the icy comet nucleus, the comet was photographed late in the night at a distance of 108 million Km from Dark Sky® Alqueva Observatory in Portugal, two hours before starts the astronomical twilight. This long distance traveller not seen in 50,000 years, is moving fast against the background starry sky, and that night it was located between constellations of Hercules, Corona Borealis and Bootes, showing a faint visual magnitude of +7.3.

Rho Ophiuchi Cloud Complex Shining in a Colorful Close-up Scene
The image features a close-up view of Rho Ophiuchi Cloud Complex, one of the most colourful nebulas in space and the closest star-forming regions to the Solar System, at an estimated distance of 460 light years. These interstellar clouds of gas and dust contain both red emission nebulas and blue reflection nebulas. The dark brown regions are caused by dust grains, born in young stellar atmospheres, which effectively block light emitted behind them. The lower area of the image features many dark absorption nebulas. The dark cloud known as “Dark River”, it can be identified as the brown dust lane connected to Antares, and spans about 100 light years in direction of the central band of our Milky Way Galaxy. The distant globular cluster M4 is just seen above the red supergiant star Antares, one of the brighter stars in the night sky, though it lies far behind the colourful cloud complex, at a distance of some 7,000 light-years.
PT: A imagem apresenta uma visão aproximada do complexo de nuvens Rho Ophiuchi, um dos complexos nebulosos mais coloridos do espaço e uma das regiões de formações de estrelas mais próximas ao sistema solar, localizado a uma distância estimada de 460 anos-luz, estas nuvens inter-estelares de gás e poeiras contêm nebulosas de emissão (vermelhas) e nebulosas de reflexão (azul). As regiões a castanho escuro são causadas por grãos de poeira, nascidos em atmosferas estelares jovens, que efetivamente bloqueiam a luz emitida por detrás delas. A região inferior da imagem apresenta ainda muitas nebulosas de absorção escuras. A nebulosa escura conhecida como “Dark River”, pode ser identificada como a banda de poeira castanha que está conectada à região de Antares e que se estende por 100 anos-luz de distância em direcção à banda central de nossa Galáxia, a Via Láctea. O aglomerado globular M4 pode ser visto nesta imagem, à esquerda da estrela super gigante vermelha Antares, uma das estrelas mais brilhantes do céu noturno, este aglomerado está no entanto bem atrás do complexo colorido, a uma distância de cerca de 7.000 anos-luz.

Rigel and The Witch Head Nebula Immersed in Faint Nebulosity and a Background Fullfiled by Galaxies
Located at about 800 light-years away in the constellation of Eridanus, IC 2118, also known as the Witch Head Nebula, is a large faint reflection nebula which spans about 50 light-years and is made of fine interstellar dust particles that are reflecting the strong blue light of the blue-white supergiant star Rigel, in Orion constellation, which lies at about 2.5 degrees from the Witch nebula. The field also shows portions of brown dust as this region lie on the Orion-Eridanus molecular hydrogen cloud, blown out by the powerful hot blue stars near by. Almost hidden by the bright glow of Rigel, is also possible to notice a “spermatozoid” shaped dust, like if it was scape from the stellar cradle. Many Lynds Bright Nebula, like LBN 960, LBN 959, LBN 968 are included in this deepsky colorful scene, but what most astonishing me, is the fact that if we look close and carefully, we can notice that the scene is fulfilled by hundreds of galaxies, in fact at least 370 faint distant galaxies were identified in the annotated version produced by PixInsight script, based in several known catalogues like Messier; NGC-IC; PGC; CGPN; ARP, and thus spread behind the visible background dust. See below the annotated version available in portrait and landscape mode.
PT: Localizada a cerca de 800 anos-luz de distância na constelação de Eridanus, IC 2118, também conhecida como Nebulosa da Cabeça da Bruxa, é uma grande nebulosa de reflexão ténue com uma extensão de 50 anos-luz e é feita de partículas de poeira interestelar muito finas e que refletem a forte luz azul da estrela supergigante azul-branca Rigel, na constelação de Orion, que fica a cerca de 2,5 graus da Nebulosa. O campo também mostra porções de poeira castanha dado que esta região se encontra na nuvem molecular de hidrogénio Orion-Eridanus, soprada pelas poderosas estrelas azuis quentes mais próximas. Quase escondido pelo brilho intenso de Rigel, também é possível notar uma poeira em forma de “espermatozóide”, como se estivesse a escapar do berço estelar. Muitas “Lynds Bright Nebula”, como LBN 960, LBN 959, LBN 968 estão incluídas neste cenário colorido do céu mais profundo, mas o que mais me surpreende neste imagem, é perceber que se olharmos de perto e com atenção, podemos notar que este cenário celeste está preenchido por centenas de galáxias, na verdade, pelo menos 370 galáxias distantes ténues foram identificadas na versão anotada produzida pelo script do PixInsight – baseado em vários catálogos reconhecidos como Messier; NGC-IC; PGC; CGPN; ARP – e que assim se espalham por de trás da poeira de fundo visível. Veja em baixo a versão anotada da imagem disponível em modo retrato e paisagem.

NGC 7000 North America Nebula Revealing Complex Structures of Fine Details from Hydrogen-alpha Light
NGC 7000 is a bright emission nebula tracing the continental shape of North America. Discovered by William Herschel on 1786, it lies at about 1,500 light-years away from us, belonging to a larger complex of bright red emission nebulosity and surrounded by dark nebulae in the constellation of Cygnus, at about 3º from Deneb star. The “Gulf of Mexico” is a region where the obscured dust lanes are visible from dark nebula LDN 935, while “Mexico and Central America” reveals the bright interesting and intricate area known as the Cygnus Wall, a true stellar nursery of newly formed stars. The wall is eroded and illuminated by bright young stars, partially not visible for being occulted behind the dust they have just created. The image captured from Dark Sky® Alqueva observatory, comprise RGB images combined with narrowband 7 nanometer hydrogen-alpha images. Like an art painting from Nature, a starless and less distractive version of only the monochrome Ha light and the result of HaRGB, shows the brightest regions in an incredibly sharp rich field shaped by complex structures of fine details from hydrogen-alpha nebulosity, against the fine dark dust lanes, particularly visible close to the Cygnus Wall. Both versions are available in portrait and landscape mode, to help conduct the reader attention for the most interesting parts of the image.
PT: NGC 7000 é uma nebulosa de emissão brilhante que traça a forma continental da América do Norte. Descoberta por William Herschel em 1786, encontra-se a cerca de 1.500 anos-luz de nós, pertencendo a um complexo muito grande de nebulosidade de emissão vermelha brilhante hidrogénio-alfa (Ha) e rodeado por nebulosas escuras localizado na constelação do Cisne, a cerca de 3º da estrela Deneb. O “Golfo do México” é uma região onde as faixas de poeira obscurecidas são visíveis da nebulosa escura LDN 935, enquanto “México e América Central” revela a interessante e intrincada área brilhante conhecida como Muralha do Cisne, um verdadeiro berçário estelar de estrelas recém-formadas. A parede está erodida e iluminada por estrelas jovens e brilhantes, parcialmente ocultadas pela própria poeira que acabaram de criar. A imagem captada a partir do observatório oficial do Dark Sky® Alqueva, na Cumeada, compreende a combinação de imagens RGB na faixa da luz visível, combinadas com imagens de hidrogénio-alfa em banda estreita de 7 nanómetros. Como uma pintura de arte da própria Natureza, uma versão sem estrelas e menos distrativa apenas da luz monocromática Ha e o resultado de HaRGB, mostra as regiões mais brilhantes em um campo incrivelmente nítido e rico, moldado por estruturas complexas de detalhes finos de nebulosidade hidrogénio-alfa contra finas faixas de poeira escura, particularmente visíveis perto da Muralha do Cisne. Ambas as versões estão disponíveis em modo retrato e paisagem, para ajudar a direcionar a atenção do leitor para as partes mais interessantes da imagem.

Colorful Deep Cosmic Portrait of Orion Molecular Cloud Complex
A deep wide field view captured with a telephoto prime lens of 300mm, shows the wonderful Orion Molecular Cloud Complex. Horsehead Nebula is visible in the upper left corner of this cosmic portrait, and Orion Nebula in the lower center. Both are immersed in the reddish emission from the light of hydrogen gas excited by energetic newly-formed hot and young stars. Blue-violet coloration, comes from the reflected radiation from the massive O-class stars. This complex contains dark nebulae, emission nebulae, reflection nebulae, and H II regions. The wide view also includes, Alnitak, Alnilam and Mintaka, the 3 main bluish bright stars of Orion’s Belt, in the constellation of Orion. Both M42 (Orion Nebula) and Barnard 33 (Horsehead) are located at a distance between 1350 and 1500 light years respectively and are the closest region of massive star formation to Earth. Small white and brown clouds are visible near Alnilam and Mintaka revealing a busy and colorful field with portions of dense gas which seems to be illuminated by the surrounding starlight. The image was captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Portugal.
PT: Uma visão ampla e profunda captada com uma lente prime de 300mm mostra o maravilhoso complexo molecular de Orion. A Nebulosa Cabeça de Cavalo é visível no canto superior esquerdo deste retrato cósmico, e a Nebulosa de Orion no centro inferior. Ambos estão imersos numa tonalidade avermelhada, resultado de uma emissão brilhante a partir do gás de hidrogénio excitado por estrelas quentes e energéticas, recém-formadas. A coloração azul-violeta visível na fotografia, provém da radiação refletida das estrelas da classe-O. Este complexo contém nebulosas escuras, nebulosas de emissão, nebulosas de reflexão e regiões H II. Esta visão ampla também inclui, Alnitak, Alnilam e Mintaka, as 3 principais estrelas brilhantes e azuladas que compõem o Cinturão de Orion, na constelação de Orion. Tanto a M42 (Nebulosa de Orion) quanto o Barnard 33 (Cabeça de Cavalo) estão localizadas a uma distância entre 1350 e 1500 anos-luz, respectivamente, sendo a região de formação estelar massiva mais próxima da Terra. Pequenas nuvens brancas e castanhas são visíveis perto de Alnilam e Mintaka, revelando um campo diversificado e colorido com porções de gás denso que parece ser iluminado pela luz das estrelas ao redor. A imagem foi captada no Observatório da Cumeada, Sede Oficial da Reserva Dark Sky® Alqueva, Portugal.

Polaris Immersed in the Faint Dust Clouds from Integrated Flux Nebula – IFN
A deep wide field view shows the star Polaris immersed in the faintest diffuse clouds from IFN, the gas and dust from Integrated flux nebulas (IFN) which lies beyond the main body of our Milky Way Galaxy. According to its discoverer Steven Mandel (2005), they are “high galactic latitude nebulae that are illuminated not by a single star (as most nebula in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way. These nebulae clouds – an important component of the interstellar medium – are composed of dust particles, hydrogen and carbon monoxide and other elements”. Not visible though in a single long exposure, to show a result like these, I had to left my camera exposing for several nights in order to accumulate a total amount of 13 hours, to be able to reveal the faintest light of IFN also immersed in a colorful starfield which surrounds Polaris, well known, as the Northern Star.
PT: Uma visão ampla e profunda mostra a estrela Polar imersa nas nuvens difusas e ténues de gás e poeira da Nebulosa de Fluxo Integrado (IFN) e que ficam para além do corpo principal da nossa galáxia. De acordo com seu descobridor Steven Mandel (2005), estas são “nebulosas de alta latitude galáctica que são iluminadas não por uma única estrela (como a maioria das nebulosas no plano da Galáxia), mas pela energia do fluxo integrado de todas as estrelas da Via Láctea. Essa nebulosas – um importante componente do meio interestelar – são compostas essencialmente por partículas de poeira, hidrogénio e monóxido de carbono, entre outros elementos”. Não sendo contudo visíveis em uma única longa exposição, para mostrar um resultado como este, foi necessário fazer longas exposições por várias noites até acumular um total de 13 horas, para assim poder revelar a fraca nebulosidade da IFN, imersa em um campo estelar colorido que circunda a estrela Polaris, também conhecida por Estrela do Norte.
Above – A cropped portrait and starless version shows interesting details and intricate structures on the IFN clouds. These different perspectives above and below, intended to help conduct the reader attention to the most interesting parts of the image.

The Crowded Starfield Around Lagoon, Trifid and NGC 6559
A deep wide scene shows the dusty and crowded starfield which surrounds Sagittarius constellation, spanning in the direction of the galactic core of Milky Way. Three bright nebulae are visible, as well as two small globular clusters against the brightest dusty part of this background field divided by dark and light regions. M8 or the Lagoon Nebula, is the largest emission nebula and a stellar nursery visible, and close to the left, shines NGC 6559, a nebulae complex which seems to be separated from the Lagoon by a dark dust lane, also containing dark nebulae B91 and B303, and the bright nebulae IC 4684, 4685 and IC 1274/5. Far from NGC6559 in the opposite direction and close to the edge of the image, lies the colorful Trifid Nebula M20, a complex of red emission and blue reflection nebulosity intersected by three dark lanes, from which the Trifid gets its own name. Close to Trifid, it’s also visible a rich open cluster of bluesish stars known as M21. Captured in Cumeada Observatory from Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.

A Blue Horse Head is Shining in Space Surrounded by Faint Dust
Located at a distance of 400 light-years in the constellation of Scorpius, lies a wonderful nebula named IC4592 but better known by it’s well distinguished shape of a Blue Horse Head. The entire area is part of a large and colorful molecular cloud in Scorpius and Ophiuchus. The blue reflection nebula is made up of very fine interstellar dust particles that reflects the visible light of energetic nearby stars, as Nu Scorpii, the bright blueish star which marks the eye of the Horse. Immersed in the brownish dust, is visible a second reflection nebula named IC 4601 surrounding two stars. The whole field captured with a 300mm fixed prime lens, can also reveal in the background sky some of the faintest dust which seems to surround the main nebula.. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.
PT: Localizada a uma distância de 400 anos-luz na constelação do Escorpião, encontra-se uma incrível nebulosa chamada IC4592, mas mais conhecida pela sua forma distinta de uma Cabeça de Cavalo Azul.

A nebulosa de reflexão azul é composta por partículas de poeira interestelar muito finas que refletem a luz visível de estrelas energéticas próximas, como Nu Scorpii, a estrela azul brilhante que marca o olho do Cavalo. Imerso na poeira acastanhada, é visível uma segunda nebulosa de reflexão chamada IC 4601 em torno de duas estrelas. Todo este campo profundo captado com uma lente fixa de 300mm, revela ainda no céu de fundo alguma da poeira mais ténue que parece circundar a nebulosa principal.

Eagle Nebula in a Colorful Deep Field
The image shows a young open cluster of stars in the constellation Serpens Cauda, surrounded by a colorful deepsky field of glowing gas, known as the Eagle Nebula, M16. Located at a distance of 7,000 light-years away from us, the nebula features a dusty sculpture made famous by the Hubble Space Telescope’s close-up, known as the “Pillars of Creation”. These dense, dusty pillars, with light-years in length, are the location of new star formation, and are sculpted by the stellar winds from nearby newborn stars. At left of the main pillars is another dusty starforming column known as the Fairy of Eagle Nebula. The gas and dust in the giant cloud of M16, has given birth to hot and young stars in the star cluster embedded in the nebula. The ultraviolet energy from these stars cause the nebula to glow with red hues, from the ionized hydrogen-alpha emission.
PT: A imagem mostra um jovem aglomerado aberto de estrelas na constelação Serpens Cauda, rodeado por um campo profundo de gás brilhante, conhecido como a Nebulosa da Águia, M16. Localizada a uma distância de 7.000 anos-luz de nós, a nebulosa apresenta uma escultura empoeirada que ficou famosa pelo close-up do Telescópio Espacial Hubble, conhecida como “Pilares da Criação”. Esses pilares densos e empoeirados, com vários anos-luz de comprimento, são o local de formação de novas estrelas e são esculpidos pelos ventos estelares de estrelas recém-nascidas próximas. À esquerda dos pilares principais está outra coluna densa de formação de estrelas conhecida como a Fada da Nebulosa da Águia. O gás e a poeira na nuvem gigante da M16 ,deram origem a estrelas jovens e quentes no aglomerado de estrelas embutido na nebulosa. A energia ultravioleta dessas estrelas faz com que a nebulosa brilhe em tons vermelhos, a partir da emissão ionizada de hidrogénio-alfa.

Orion Nebula Immersed in the Reddish Emission from Hydrogen Gas
A deep wide field view shows Orion Nebula M42, immersed in the reddish emission from the light of hydrogen gas excited by energetic newly-formed hot and young stars. Blue-violet coloration, comes from the reflected radiation from the massive O-class stars. This complex contains dark nebulae, emission nebulae, reflection nebulae, and H II regions. The Orion Nebula (M42) is a diffuse and large nebula complex situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion, is one of the brightest and beautiful nebulae also visible to naked eye in the night sky. M42 is located at a distance of about 1350 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. This nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula. Below, in the lower left corner, is partially visible the red cloud where is located the well known Horse-head nebula. But besides this colorful field captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Portugal, a nice faint galaxy and another less bright, can both be visible in the upper right corner of the image.

A Nebulosa de Orion (M42) é um grande complexo nebuloso difuso situado na Via Láctea, a sul do Cinturão de Orion na constelação de Orion, sendo também uma das mais brilhantes e fascinantes nebulosas visíveis a olho nu no céu noturno. M42 está localizado a uma distância de cerca de 1350 anos-luz e é a região mais próxima da Terra na formação de estrelas maciças. A nebulosa M42 está estimada em 24 anos-luz de diâmetro. Tem uma massa de cerca de 2000 vezes a massa do Sol. O estudo desta nebulosa já permitiu revelar muito sobre o processo de como as estrelas e os sistemas planetários são formados por nuvens de gás e poeira em colapso. Os astrónomos observaram directamente discos protoplanetários, anãs castanhas, movimentos intensos e turbulentos de gás e os efeitos foto-ionizantes de estrelas maciças próximas, na nebulosa.

Mars Immersed in the Faintest dust of Pleiades Star Cluster
A wide field deep view of the winter sky comprising 5h of expousure captured with a 300mm lens at f/2.8, shows planet Mars visiting the faintest (IFN) nebulosity which seems to surround Pleiades or Seven Sisters (M45), an open cluster containing hot and young stars. The blue nebulosity that surrounds the cluster, is a reflection nebula scattering the blue starlight. The cluster contains about 1,000 stars, of which more than a dozen can be seen with the unaided eye during winter time in the Northern Hemisphere. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.

A Cosmic Angel in Space
Located in the constellation of Monoceros (Unicorn), the image shows the dusty brown-reddened field which seems to surround a central colorful cosmic Angel, also known as NGC 2170. The Angel Nebula is featuring a red emission nebulae along the pink skirt crossed by a dark belt of absorption nebulae, while the wings of the angel are just reflecting the light of nearby hot stars, forming a bluish reflection nebulae. Along the end of this angelic cosmic dress, adorning the seam of the pink skirt, we can find a beautiful small cluster of colorful diffuse stars adding a final touch of glamour to this celestial portrait, which comprise a total amount of 18 hours of exposure, captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.
PT: Localizada na constelação de Monoceros (Unicórnio), a imagem revela o campo poeirento castanho avermelhado que parece circundar um colorido Anjo cósmico ao centro, também conhecido como NGC 2170. A Nebulosa do Anjo apresenta uma nebulosa de emissão vermelha ao longo da “saia rosa-violeta” atravessada por um cinturão escuro de nebulosas de absorção, enquanto as asas do anjo estão apenas a reflectir a luz de estrelas quentes situadas nas proximidades, formando assim uma nebulosa de reflexão azulada. Ao longo deste vestido cósmico angelical, adornando a costura da saia rosa-violeta, podemos encontrar um lindo e pequeno aglomerado de estrelas difusas coloridas que acresentam um toque final de glamour a este retrato celestial, que condensa um total de 18 horas de exposição captadas a partir do Observatório da Cumeada, Sede Oficial do Dark Sky@ Alqueva, Reguengos de Monsaraz, Portugal.

Andromeda Galaxy Immersed in Clouds of Glowing Ionized Hydrogen
With approximately 220,000 light-years across, Andromeda is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum galaxy, and about 30 other smaller galaxies. The large spiral galaxy comprises dark dust lanes in its spiral arms, traced by blueish hues of reflected starlight and a yellowish bright center. Inspired by Rogelio´s work (RBA) while capturing and describing for the first time this strange cirrus dust of faint reddish light surrounding Andromeda, the image features a long exposure of RGB light combined with Ha emission, to show the colorful field of faint glowing ionized hydrogen gas where the galaxy seems to be immersed in. I was surprised that despite this faint clouds, all the galaxy shape has a strong emission visible with Ha 7nm filter. These clouds formations visible in the foreground, belongs to our own Milky Way, as well as the several distinct colorful stars which surrounds the diffuse spiral shape. While its spiral arms stand out in visible light images, the arms look like rings in the GALEX ultraviolet views. Being sites of intense star formation, the rings have been interpreted as evidence that Andromeda collided with its smaller neighbouring elliptical galaxy M32 more than 200 million years ago. M32 is also visible as the bright circular diffuse shape on the right side of the core. M110, a dwarf elliptical galaxy visible above M31, is also a satellite of the Andromeda Galaxy. Captured in Cumeada Observatory from Dark Sky® Alqueva Reserve, Reguengos, Portugal.
PT: Com aproximadamente 220.000 anos-luz de diâmetro, Andrómeda é a maior galáxia do Grupo Local, que também contém a Via Láctea, a galáxia do Triângulo e cerca de 30 outras galáxias menores. A grande galáxia espiral compreende faixas de poeira escura nos seus braços espirais, traçados por tonalidades azuis que reflectem a luz das estrelas e um centro brilhante amarelado. Inspirada no trabalho de Rogelio (RBA) ao captar e descrever pela primeira vez esta estranha poeira cirrus de luz avermelhada que envolve Andrómeda, a imagem mostra várias horas de exposição na faixa da luz visível RGB, combinada com a emissão Ha, para permitir assim revelar o brilho ténue de gás hidrogénio ionizado onde a galáxia parece estar imersa. Fiquei surpreso que, apesar dessas nuvens muito ténues, toda a forma da galáxia tem uma forte emissão visível com o filtro Ha 7nm. Essas formações de nuvens visíveis em primeiro plano, pertencem à nossa própria Via Láctea, assim como as várias estrelas coloridas distintas que envolve a forma espiral difusa. Enquanto seus braços espirais se destacam em imagens de luz visível, os braços parecem anéis quando vistos no ultravioleta através do GALEX (Galaxy Evolution Explorer ). Sendo locais de intensa formação estelar, os anéis têm sido interpretados como evidência de que Andromeda colidiu com sua menor galáxia elíptica vizinha M32, há mais de 200 milhões de anos. M32 também é visível como a forma difusa circular brilhante no lado direito do núcleo da M31. M110, uma galáxia elíptica anã visível acima de M31, é também um satélite da galáxia de Andromeda.

Andromeda Galaxy Shinning in Visible Light
Homo is the genus that includes modern humans and their close relatives, originals habitants of planet Earth.The genus is estimated to be between 1.5 and 2.5 million years old. At approximately the same time, in space, the light from our neighboring galaxy Andromeda M31, has departed from the point in space where it is located, in the constellation of Andromeda. While the light from this source was travelling in the cold vacum of space at the speed of light, for the long journey of 2.5 million years, here in our planet, we have been evolved from the Homo Habilis up to the point where we have the necessary technology to construct powerful telescopes, giving us the capability to observing, studying, photographing and understanding the wonders of the vast Universe. Besides the huge distances, Andromeda galaxy is the nearest spiral galaxy to our Milky Way. With approximately 220,000 light-years across, Andromeda is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum galaxy, and about 30 other smaller galaxies. This colorful scene shows the arms and core of Andromeda immersed in several distinct stars that surrounding the diffuse spiral shape, are actually stars from our own galaxy, the Milky Way, well visible in front of M31. To see Andromeda immersed in clouds of faint glowing ionized hydrogen gas, click here. While its spiral arms stand out in visible light images, the arms look like rings in the GALEX ultraviolet views. Being sites of intense star formation, the rings have been interpreted as evidence that Andromeda collided with its smaller neighboring elliptical galaxy M32 more than 200 million years ago. M32 is also visible as the bright circular diffuse shape on the right side of the core. M110, a dwarf elliptical galaxy visible above M31 (landscape version), is also a satellite of the Andromeda Galaxy.

PT: Homo é o género que inclui os humanos modernos e seus parentes próximos, habitantes originários do planeta Terra. Este Género está estimado entre 1,5 e 2,5 milhões de anos. Aproximadamente ao mesmo tempo, no espaço, a luz da nossa galáxia vizinha Andromeda M31, partiu do ponto onde está localizada, na constelação de Andromeda. Enquanto a luz desta fonte viajava no vácuo frio do espaço à velocidade da luz, durante a longa jornada de 2,5 milhões de anos que nos separa, aqui no nosso planeta, evoluímos do Homo Habilis até ao ponto actual em que temos a tecnologia necessária para construir telescópios poderosos, dando-nos a capacidade de observar, estudar, fotografar e compreender as maravilhas do vasto universo. Apesar destas distâncias enormes, a galáxia de Andromeda é a galáxia espiral mais próxima da nossa galáxia, a Via Láctea. Com cerca de 220.000 anos-luz de diâmetro, Andromeda é a maior galáxia do Grupo Local, que também contém a Via Láctea, a galáxia de Triângulo, e cerca de 30 outras galáxias menores.

Blueish Iris Nebula Involved in a Colorful Field of Interstellar Dust
Lying at a distance of 1,300 light-years in the rich constellation of Cepheus, involved among faint and dark interstellar dust is the blueish Iris nebula also knwon as NGC 7023. Strong blue light from the bright young star SAO 19158 is reflected by the surounding dust, while the brown tint visible on dark grainy dust comes partly from the conversion of some invisible ultraviolet radiation into red light, a phenomemon also known as photoluminescence. The blueish dust visible on this colorful starryfield span about six light-years. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.

The Colorful Region of NGC 6559 in Sagittarius
Being part of the same molecular cloud complex as Lagoon Nebula, but located to east-northeast of M8, this star field region is rich in diversity. The field shows a red glowing emission nebulas from hydrogen gas, dark absorption nebulas, as well as blue reflection nebulas of dust, surrounded by the stars that has been formed from them. At the center of the scene is visible IC 1274 and IC1275, both circular red HII regions separated by a rim of blue reflection nebulosity featured above the large dark nebula B91. On the upper right corner (all the indication regards the portrait version) are clouds rich in hot glowing gas, being NGC 6559 the brightest reddish section. The blue nebula visible is reflecting light from a group of massive blue stars. Small Dark nebulas B302 and B303 are surrounding the brightest star located just to the upper left of NGC 6559, which spans about 3 light years and likely has a common history with the Lagoon Nebula. The complex lies about 5000 light-years away toward the constellation of Sagittarius. According to Nasa, “first massive stars formed from the dense gas will emit energetic light and winds that erode, fragment, and sculpt their birthplace. And then they explode. The resulting morass can be as beautiful as it is complex. After tens of millions of years, the dust boils away, the gas gets swept away, and all that is left is a naked open cluster of stars.” All this complex is involved by a large open cluster known as Cr 367.
PT: Pertencendo ao mesmo complexo de núvens moleculares da Nebulosa da Lagôa, mas localizado a Este-nordeste de M8, esta região estelar é rica em uma grande diversidade de objectos de céu profundo. Este campo de visão captado a partir do Observatório Oficial do Dark Sky® Alqueva, na Cumeada, revela assim uma variedade entre nebulosas de emissão brilhantes vermelhas de gás hidrogénio, nebulosas de absorção escuras, bem como nebulosas de reflexão azul, rodeadas pelas estrelas que se formaram a partir de algumas destas nebulosas. No centro deste cenário cósmico são visíveis os objectos IC 1274 e IC1275, ambos regiões HII vermelhas circulares, aparentemente “interrompidas” por uma extremidade de nebulosidade de reflexão azul que se apresenta acima da grande nebulosa escura B91. No canto superior direito (todas as indicações se referem à versão vertical – em formato de retrato) estão núvens ricas em gás quente brilhante, sendo NGC 6559 a seção avermelhada mais brilhante. A nebulosa azul visível está refletindo a luz de um grupo de grandes estrelas azuis. Pequenas nebulosas negras como B302 e B303 ecircundam a estrela mais brilhante localizada logo acima e à esquerda de NGC 6559, a nebulosa que se estende por cerca de 3 anos-luz e provavelmente tem uma história comum com a nebulosa da lagoa. O complexo fica a cerca de 5.000 anos-luz de distância em direção à constelação de Sagitário. De acordo com a Nasa, “as primeiras estrelas massivas formadas a partir do gás denso emitirão luz energética e ventos que erodem, fragmentam e esculpem seu local de nascimento. E então explodem. O pântano resultante pode ser tão bonito quanto complexo. Depois de dezenas de milhões de anos, a poeira evapora, o gás é varrido e tudo o que resta é um aglomerado aberto de estrelas. ” Todo esse complexo está envolvido por um grande aglomerado aberto conhecido como Cr 367.

Comet Neowise Featuring Synchronic Bands, Green Coma and Bluish Ion Tail
The image shows a close-up view of Comet Neowise C/2020 F3 featuring a detailed view of Synchronic bands, also known as “striae,” these bands are dividing the comet’s dust tail into linear regions of greater and lesser density. According to Spaceweather, “Synchronic bands have been seen in comet tails for centuries, yet only recently have astronomers begun to understand what they are. The turning point came in 2007 when European and NASA spacecraft observed the formation of striae in Comet McNaught (C/2006 P1). The process starts when a chunk of comet detaches itself from the nucleus. Boulder-sized chunks fragment into smaller and smaller pieces, a cascade shaped into long streamers by solar radiation pressure”. Also visible in this portrait sky scene captured with a telephoto lens of 140mm and tracked with a portable mount Vixen Polarie, is a long blueish ion tail made by ionised gas – gas energised by ultraviolet light from the Sun and pushed outward by the solar wind. Travelling at a speed of 231 000km/h, the comet orbits the sun every 6,800 to 7,000 years. Neowise is currently at about 111 million kilometres away from Earth, while featuring a 5km in diameter green head of diatomic carbon (C2) – gas fluorescing in sunlight which is producing the coma’s green color. Captured on 17th July 2020 from Dark Sky® Vale do Tua, north of Portugal.
PT: A imagem mostra um close-up do cometa Neowise C / 2020 F3, revelando uma visão detalhada das bandas sincrónicas, também conhecidas como “estrias”, faixas que vão dividindo a cauda de poeira do cometa em regiões lineares de maior e menor densidade. De acordo com Spaceweather, “bandas sincrónicas são vistas nas caudas de cometas há séculos, mas apenas recentemente os astrónomos começaram a entender este fenómeno e a sua natureza. O ponto de viragem ocorreu em 2007, quando as sondas europeias e da NASA observaram a formação de estrias no cometa McNaught (C / 2006 P1). O processo começa quando um pedaço de cometa se desprende do núcleo. Pedaços do tamanho de pedregulhos se fragmentam em pedaços cada vez menores, uma cascata moldada em longas serpentinas pela pressão da radiação solar “. Também visível neste retrato celeste captado com uma lente de 140mm e com uma montagem portátil Vixen Polarie, encontra-se uma onga cauda de iões azulada composta por gás ionizado – gás este energizado pela luz ultravioleta do Sol e empurrado para fora pelo vento solar. Viajando a uma velocidade de 231 000 km / h, o cometa orbita o sol a cada 6.800 a 7.000 anos. Actualmente, o Neowise está a cerca de 111 milhões de quilômetros da Terra, apresentando uma cabeça verde de carbono diatómico (C2) com 5km de diâmetro – gás fluorescente à luz solar e que está a produzir a cor esverdeada da Cabeleira ou Coma do Cometa.

Blue Horsehead Nebula and Rho Ophiuchi Cloud Complex in a Colorful Deepsky Scene
The image features a wide view of Blue Horsehead Nebula IC 4592 and Rho Ophiuchi Cloud Complex, one of the most colourful nebulas in space and the closest star-forming regions to the Solar System, at an estimated distance of 460 light years. These interstellar clouds of gas and dust contain both red emission nebulas and blue reflection nebulas. The dark brown regions are caused by dust grains, born in young stellar atmospheres, which effectively block light emitted behind them. The lower area of the image features many dark absorption nebulas. The dark cloud known as “Dark River”, it can be identified as the brown dust lane connected to Antares, and spans about 100 light years in direction of the central band of our Milky Way Galaxy. The distant globular cluster M4 is just seen above the red supergiant star Antares, one of the brighter stars in the night sky, though it lies far behind the colourful cloud complex, at a distance of some 7,000 light-years.
PT: A imagem apresenta uma visão ampla da nebulosa Blue Horsehead IC 4592 e do complexo de nuvens Rho Ophiuchi, um dos complexos nebulosos mais coloridos do espaço e uma das regiões de formações de estrelas mais próximas ao sistema solar, localizado a uma distância estimada de 460 anos-luz, estas nuvens inter-estelares de gás e poeiras contêm nebulosas de emissão (vermelhas) e nebulosas de reflexão (azul). As regiões a castanho escuro são causadas por grãos de poeira, nascidos em atmosferas estelares jovens, que efetivamente bloqueiam a luz emitida por detrás delas. A região inferior da imagem apresenta ainda muitas nebulosas de absorção escuras. A nebulosa escura conhecida como “Dark River”, pode ser identificada como a banda de poeira castanha que está conectada à região de Antares e que se estende por 100 anos-luz de distância em direcção à banda central de nossa Galáxia, a Via Láctea. O aglomerado globular M4 pode ser visto nesta imagem, à esquerda da estrela super gigante vermelha Antares, uma das estrelas mais brilhantes do céu noturno, este aglomerado está no entanto bem atrás do complexo colorido, a uma distância de cerca de 7.000 anos-luz.

The Virgo Cluster Featured as A Question Mark “?” Shape of Galaxies
The image features a Question Mark “?” shape of galaxies at a distance of 48 million light-years away from Earth, where lies the Virgo Cluster. This collection of more than a thousand galaxies located in the constellation of Virgo, forms the heart of the larger Virgo Supercluster from which the Local Group containing our own Milky Way galaxy belongs. Close to the lower left center edge lies the gigantic elliptical galaxy M87, while at the right side is visible a smoothly curved line of galaxies known as Markarian´s Chain, which also include another enormous elliptical galaxy M86 and M84, seen in the picture as a faint circular shape close to the bottom. In the top edge of this photo and the “Question Mark (?)” is also visible from left to the right, colorful galaxies M90, M91 and M88.
PT: A imagem revela um conjunto de galáxias que parece estar disposta na forma de um “Ponto de Interrogação (?)” e a uma distância de 48 milhões de anos-luz da Terra, onde fica o chamado Aglomerado de Virgem. Esta colecção de mais de mil galáxias localizadas na constelação de Virgem, forma o coração do maior superaglomerado de Virgem, do qual pertence o Grupo Local que contém a nossa própria galáxia, a Via Láctea. Perto do centro esquerdo inferior da imagem, encontra-se a gigantesca galáxia elíptica M87, enquanto no lado direito é visível uma linha de galáxias suavemente curvada, conhecida como a Cadeia de Markarian, que também inclui outra enorme galáxia elíptica a M86 e M84, vistas na fotografia como duas manchas circulares grandes e difusas. No extremo superior desta foto e do “ponto de interrogação (?)”, também é visível da esquerda para a direita, as galáxias coloridas M90, M91 e M88.

Triangulum Galaxy M33 Featuring Pinkish Hydrogen Clouds Spread Along the Arms
Located in the constellation of Triangulum at a distance of 3 million light-years away from Earth, lies Messier 33. The Triangulum Galaxy, is a beautiful large face-on spiral galaxy with a diameter of 50,000 light-years, being the third-largest member of our Local Group of galaxies, which includes Andromeda Galaxy M31 and our own Milky Way with his companions, the Magellanic Clouds. This cluster os galaxies belongs to a much larger super-cluster known as the Virgo cluster. Due to their interactions, velocities, and proximity, scientists suspect that M33 could be a satellite of Andromeda Galaxy M31. The image shows pinkish ionised hydrogen clouds (HII regions), spread along the spiral arms of Triangulum Galaxy. These giant HII regions are some of the largest known stellar nurseries. NGC 604, is the largest star forming region with its glowing hydrogen gas visible in the upper right center of the galaxy.
PT: Localizada na constelação do Triângulo, a uma distância de 3 milhões de anos-luz da Terra, fica a M33. A Galáxia do Triângulo é uma grande galáxia espiral com um diâmetro de 50.000 anos luz, sendo o terceiro maior membro do nosso Grupo Local de galáxias, que inclui a galáxia de Andrómeda M31 e a nossa própria Via Láctea com as suas companheiras, Nuvens de Magalhães. Este aglomerado de galáxias pertence a um super aglomerado muito maior, conhecido como o aglomerado de Virgem. Devido às suas interações, velocidades e proximidade, os cientistas suspeitam que a M33 possa ser um satélite da galáxia de Andrómeda M31. A imagem revela nuvens rosadas de hidrogénio ionizado (regiões HII), espalhadas ao longo dos braços espirais da galáxia do Triângulo. Essas regiões gigantes HII são alguns dos maiores berços estelares conhecidos. NGC 604 é assim a maior região de formação estelar, com o seu gás de hidrogénio a brilhar visível no centro superior direito da galáxia.

Hyades and Pleiades Shinning in The Colorful Dusty Field of Taurus
A wide field view of the winter sky shows a duet of open clusters involved in the faint dust from Taurus constellation. In the bottom of this deep sky scene captured with a Sigma Art 105 mm lens and comprising almost 5h of exposure, to reveal the faintest nebulosity which seems to surround this rich area of the sky, Pleiades or Seven Sisters (M45) is shinning as an open cluster containing hot and young stars. The blue nebulosity that surrounds the cluster, is a reflection nebula scattering the blue starlight. The cluster contains about 1,000 stars, of which more than a dozen can be seen with the unaided eye during winter time in the Northern Hemisphere. Spread along the scene and most evident near the right edge of the image, are visible dusty dark clouds from Taurus Molecular Cloud, which are obscuring and blocking the light behind it. On the left top corner, is shinning another beautiful and colourful open cluster known as Hyades or Melotte 25. Is believed to be 790 million years old and is comprised of 100 stars, formed at the same time and located 150 light-years away. On the top of the cluster, the brilliant red-giant star Aldebaran (Alpha Tauri), is the brightest star in the field, but not belonging to the cluster. Aldebaran is located at only 65 light-years away and lies in front of the cluster along the same line of sight. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.
PT: Uma amplo campo dos céus de inverno, revela um dueto de aglomerados abertos envolvidos na poeira subtil da constelação de Touro. Neste cenário de céu profundo captado com uma lente Sigma Art 105mm e que contempla quase 5 horas totais de exposição, para permitir revelar toda a nebulosidade mais ténue que parece envolver esta enriquecida região do céu, as Pleiades ou Sete Irmãs (M45) brilham como um aglomerado de estrelas aberto contendo estrelas muito jovens e quentes. A nebulosidade azul que envolve o aglomerado é uma nebulosa de reflexão, que espalha assim a luz azul das estrelas que se encontram na região. O aglomerado contém cerca de 1.000 estrelas, das quais uma dezena pode ser apreciada a olho nu durante o inverno no Hemisfério Norte. Espalhadas ao longo da imagem e mais evidentes perto da extremidade direita da imagem, são visíveis nuvens de poeira escura pretencentes à Nuvem Molecular do Touro, que estão obscurecendo e bloqueando a luz por detrás dela. No canto superior esquerdo, brilha outro belo e colorido aglomerado aberto, conhecido como Hyades ou Melotte 25. Acredita-se que tenha 790 milhões de anos e é composto por 100 estrelas formadas ao mesmo tempo e localizadas a 150 anos-luz de distância. No topo do aglomerado, a estrela gigante vermelha Aldebaran (Alpha Tauri) é a estrela mais brilhante de todo este campo, mas não pertence ao aglomerado. Aldebaran está localizada a apenas 65 anos-luz de distância e fica em frente do aglomerado ao longo da mesma linha de visão.

A Galactic Profile Scene of Our Own Milky Way Galaxy as Seen from the Darkest Skies of Atacama and Alqueva
A wide panoramic view comprising single exposures between 15 and 25 seconds, captured from the southern hemisphere dark skies of Atacama Desert, in Chile, and northern hemisphere dark skies of Alqueva, in Portugal, reveals a galactic profile scene of our own Milky Way galaxy. At a distance of 26,000 light-years from the dusty core, this panorama is covering approximately 239º from edge to edge. With a visible diameter of about 100,000 light-years and 2,000 light-years thick, is the second-largest galaxy in the Local Group. ESA’s Gaia mission, a dedicated project to accurately map the Milky Way in three dimensions, it is giving us new data and the most detailed map of our galactic home ever made from space, and has been refining our knowledge about this incredible spiral cosmic spaceship. On this large view captured from our planet Earth, we can see above the center bulge obscured by interstellar dust, the bright light of planet Jupiter. Beyond that, glowing nebulae, dark dust clouds and crowded starfields are all spread along the fertile galactic plane. While the lower left view of this panorama shows our neighbour spiral galaxy of Andromeda, located at approximately 2.5 million light-years from us – knowing that one day they will probably collide or mixing together – on the upper right side of the Milky Way arm, another apparently bright light belongs not to a star, but to Omega Centauri, the largest globular cluster in the Milky Way, with a diameter of roughly 150 light-years. On the left side of the image, the well know summer triangle is very well visible, being formed by Vega (in Lyra) – the brightest star above the left galaxy arm – and Deneb (in Cygnus), visible close to the eye-catching red emission North America Nebula, while Altair star (from Aquila) is visible below the arm and “towards” the galaxy core.
PT: Uma ampla vista panorâmica com exposições únicas entre 15 e 25 segundos, captadas a partir dos céus escuros do hemisfério sul no deserto de Atacama, no Chile, e a partir dos céus escuros de Alqueva no hemisfério norte, em Portugal, revela um cenário do perfil galáctico da nossa própria galáxia, a Via Láctea. A uma distância de 26.000 anos-luz do núcleo empoeirado, este panorama cobre aproximadamente 239º de ponta a ponta. Com um diâmetro visível de cerca de 100.000 anos-luz e 2.000 anos-luz de espessura, é a segunda maior galáxia do Grupo Local. A missão Gaia da ESA, um projeto dedicado a mapear com precisão a Via Láctea em três dimensões, fornece novos dados e o mapa mais detalhado do nosso lar galáctico já alguma vez feito a partir do espaço, e aprimorando o nosso conhecimento sobre esta incrível nave espacial cósmica espiralada. Nesta visão panorâmica de larga escala, captada a partir do nosso planeta Terra, podemos ver acima do bojo (zona de poeira central) obscurecido pela poeira interestelar, a luz brilhante do planeta Júpiter. Mais além, nebulosas brilhantes, nuvens escuras de poeira e campos estelares ricos, espalham-se pelo fértil plano galáctico. Enquanto a vista inferior esquerda deste panorama mostra a galáxia espiral vizinha de Andrómeda, localizada a aproximadamente 2,5 milhões de anos-luz de nós – sabendo que um dia estas provavelmente colidirão ou se misturarão – no lado superior direito do braço da Via Láctea, outra luz aparentemente brilhante se destaca, não pertencendo a uma estrela, mas sim a Omega Centauri, o maior aglomerado globular da Via Láctea, com um diâmetro de aproximadamente 150 anos-luz de diâmetro. No lado esquerdo da imagem, o conhecido triângulo de verão encontra-se bem destacado, sendo formado por Vega (Lyra) – a estrela mais brilhante acima do braço esquerdo da galáxia – e Deneb (Cygnus), visível próximo da charmosa nebulosa de emissão vermelha América do Norte, enquanto a estrela Altair (Aquila) é visível abaixo do braço e “em direção” ao núcleo da galáxia.

Planet Venus Transiting The Pleiades Star Sluster Revealed in a Deep Blue Dusty Field
The images shows planet Venus transiting in front of Pleiades star cluster, seen as an extra bright star over the Seven Sisters (Messier 45 or M45) on April 3, 2020. Pleiades is an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The cluster contains 1,000 stars, of which more than a dozen can be seen with the unaided eye. The celestial entity has several meanings in different cultures and traditions.
The blue nebulosity that surrounds the cluster is a reflection nebula. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years, and are located 391 light-years away according to measurements made by the Hipparcos satellite. The named members of the Pleiades and their magnitudes are: Pleione – 5.2 | Atlas – 3.8 | Alcyone – 3.0 | Merope – 4.3 | Electra – 3.8 | Celaeno – 5.4 | Taygeta – 4.4 | Maia – 4.0 | Sterope – 5.9.
The image above is a composite of frames captured on April 3, 2020 while Venus was in conjunction with Pleiades with the presence of the Moon, plus data collected in 2016 with the same equipment, to help revealing a deeper view of all the faint dust surrounding the cluster.
PT: A imagem revela o Planeta Vénus transitando sobre o enxame aberto de estrelas, Pleiades, no passado dia 3 de Abril de 2020, como se de uma estrela extra se tratasse no meio das “Sete Irmãs”, como é popularmente designado, sendo que é tecnicamente conhecido por Messier 45 ou M45. As Pleiades são um aglomerado de estrelas aberto contendo estrelas de meia-idade, tipo B quentes, localizadas na constelação do Touro. Está entre os aglomerados de estrelas mais próximos da Terra e é o aglomerado mais óbvio a olho nu no céu noturno. Este cluster, contém cerca de 1000 estrelas das quais mais de uma dúzia podem ser vistas a o olho nu para um observador experiente e com boa acuidade visual. Este objecto celeste tem vários significados em diferentes culturas e tradições.
A nebulosidade azul que circunda o cluster é uma nebulosa de reflexão. O cluster é dominado por estrelas azuis quentes e extremamente luminosas que se formaram nos últimos 100 milhões de anos e estão localizadas a 391 anos-luz de distância da Terra de acordo com as medições feitas pelo satélite Hipparcos. As principais estrelas das Plêiades e suas magnitudes aparentes são: Pleione – 5.2 | Atlas – 3,8 | Alcyone – 3.0 | Merope – 4.3 | Electra – 3.8 | Celaeno – 5.4 | Taygeta – 4.4 | Maia – 4.0 | Sterope – 5,9
A imagem é o resultado de um composto de exposições captadas em 3 de abril de 2020, enquanto Vénus se encontrava em conjunção com as Pleiades na presença da Lua crescente, e imagens captadas em 2016 sem a presença da Lua e com o mesmo equipamento, para permitir assim revelar uma visão mais profunda de toda a poeira envolvente ao redor deste aglomerado.
Below is a time lapse short sequence showing the formation of the Corona, around Venus.

Whirlpool Galaxy M51 Immersed in a Wide Field of Faint Galaxies in Canes Venatici
Located near the boundaries of constellation Canes Venatici, close to Ursa Major, at a distance of about 31 million light-years away from us, lies the Galaxy M51. Also known as Whirlpool Galaxy, it´s an interacting spiral galaxy, with 60 thousand light-years in diameter which has a smaller companion with an intriguing shape, named NGC 5195. The main galaxy of this duet, is featuring detailed and colorful spiral arms with dust lanes, which seems to interact with its small companion galaxy (at left on the landscape view, or up, in the portrait version) creating a faint tidal of debris that seems to spread while vanishing in space. On the portrait view (version below), in the lower right corner is visible a small faint shape belonging to another galaxy, NGC5169, and further up, another one, IC4263. Very close to NGC5195 (above on the portrait one) is visible an even “smaller” galaxy, IC4277 while in the right top corner of the image we can see PGC91291featuring a magnitude of +16.84. But how many faint galaxies do you think that can be seen in this field ? I found at least 10, being the faintest one near magnitude +17.62 (PGC2300341). But there are probably may more waiting for your patience, so instead of playing on finding “Wally”, give yourself a chance and try to see how many more distant galaxies you can spot. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.
PT: Localizada próximo dos limites da constelação de Canes Venatici, perto da Ursa Maior, a uma distância de cerca de 31 milhões de anos-luz de distância, fica a Galáxia M51. Também conhecida como Whirlpool Galaxy, é uma galáxia espiral interagente, com 60 mil anos-luz de diâmetro, que possui uma companheira menor e com uma forma intrigante e peculiar, chamada NGC 5195. A galáxia principal deste dueto, apresenta braços espirais detalhados e coloridos, com faixas de poeira escura, e que parecem interagir com a companheira de viagem mais pequena (à esquerda na versão da imagem horizontal, ou acima, na versão da imagem vertical), criando uma leve maré de detritos que parecem espalhar-se enquanto desaparecem suavemente no espaço profundo. Na vista de retrato (vertical), no canto inferior direito é visível uma pequena forma oval de brilho fraco pertencente a outra galáxia, NGC5169, e mais acima, uma outra, a IC4263. Muito perto da NGC5195 (acima, na versão de retrato) é visível uma galáxia ainda “menor”, a IC4277, enquanto no canto superior direito da imagemé possível ver a PGC91291, apresentando uma magnitude de + 16,84. Mas quantas galáxias fracas o leitor acha que podem ser vistas neste campo? Eu encontrei pelo menos 10, sendo a mais fraca perto da magnitude + 17,62 (PGC2300341). Mas provavelmente há mais à espera, pelo que se for paciente, em vez de tentar encontrar “Wally”, dê a si mesmo uma chance e tente ver quantas galáxias mais distantes você consegue identificar.

Betelgeuse Featuring Pickett’s Bell Dark Ring with Lambda Orionis and Rosette Nebula
A wide angle view pointing deep into the region of the sky near Orion constellation, reveals the faint dark nebulosity which seems to spread between Barnard´s Loop nebula, located on the left edge, Lambda Orionis nebula, as seen in the bottom, and Rosette nebula, shinning in to top right corner. All of these objects are red emission nebulae featuring colorful red-violet hues from the glowing hydrogen gas, but what highlights the image center, is the red supergiant star Betelgeuse. Surrounded by a faint dark ring with the shape of a Bell, this dark ring also known as “Pickett’s Bell”, was noticed for the first time by astrophotographer Tom Pickett in 2015. This strange bell shaped object was not listed nowhere, so Tom just called it the “Pickett’s Bell”. The blue bright star in the left corner, is Bellatrix, and Meissa, is the star shinning in the center of Lambda Orionis, both belonging to Orion constellation. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.
PT: Uma visão grande angular do espaço profundo em torno da constelação de Orion, revela uma fraca nebulosidade escura que se parece espalhar por entre as nebulosas Barnard´s Loop, localizada na lateral esquerda da imagem, assim como Lambda Orionis, na parte inferior, e a nebulosa da Roseta, que brilha intensamente no canto superior direito. Todos estes objetos são nebulosas de emissão que apresentam os tons coloridos e característicos – vermelho-violeta – proveninentes do gás hidrogénio, mas o que se destaca no centro desta imagem, é a estrela supergigante vermelha Betelgeuse. Cercada por um leve anel escuro com a forma de um sino, esse anel escuro é também conhecido como “Pickett’s Bell”, foi notado pela primeira vez pelo astrofotógrafo Tom Pickett em 2015. Este objeto estranho em forma de sino não constava assim de nenhuma lista ou catálogo oficial, então o Tom deu-lhe o nome de “Sino de Pickett”. A estrela azul brilhante no canto esquerdo é Bellatrix e Meissa, é a estrela que brilha no centro de Lambda Orionis, ambas pertencentes à constelação de Orion.

Christmas Tree and Cone Nebula in a Colorful Cloud of Glowing Gas
Featured as NASA´s APOD – Astronomy Picture of the Day the image shows a reddish skyscape scene from Monoceros constellation. A wide cloud complex of glowing hydrogen gas located at about 2,700 light-years away from us, and mixed with interstellar clouds of dark dust. Near the center image, an active star forming region features the Cone Nebula NGC2264 (LDN 1613), a dark absorption nebula with 7 light-years in length. Distinctively shaped by energetic stellar winds produced by hot and young stars recently created inside the nebula, over the course of time, only the densest portions from the original molecular cloud will remain intact and may could give form to new stars and planets. Close to it, the blue-white supergiant star S Monocerotis is the brightest star shinning in the field of a blue reflection nebulae, powered by it´s ultraviolet light and the other hot young blue stars in the Christmas Tree Cluster. These group of colorful stars in NGC2264 are forming a triangular tree shape, which the cume is the star HD 47887 that lies near the Cone head. The Fox Fur Nebula is an emission nebula which seems to partially cross in front of the blue reflection nebula at the central region of the picture. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.
PT: Destacada como NASA´s APOD – Astronomy Picture of the Day a imagem revela um cenário celeste de céu profundo a partir da constelação de Monoceros, o Unicórnio, um complexo de nuvens de gás hidrogénio avermelhado e brilhante, localizado a cerca de 2.700 anos-luz de distância de nós e misturado com nuvens interestelares de poeira escura. Perto do centro da imagem, uma região activa na formação de estrelas apresenta a Nebulosa do Cone NGC2264 (LDN 1613), uma nebulosa de absorção escura com 7 anos-luz de comprimento. Distintamente moldado por ventos estelares energéticos produzidos por estrelas quentes e jovens criadas recentemente dentro da nebulosa, ao longo do tempo, apenas as porções mais densas da nuvem molecular original permanecerão intactas e poderão vir a dar forma a novas estrelas e planetas. Perto dela, a estrela super-gigante branca-azulada S Monocerotis, é a estrela mais brilhante que se destaca no campo de uma nebulosa de reflexão azul, alimentada por sua luz ultravioleta e pela luz reflectida das estrelas jovens azuis e quentes do aglomerado da Árvore de Natal. Este grupo de estrelas coloridas do aglomerado NGC2264 apresenta assim uma disposição em forma de árvore triangular, cujo cume é a estrela HD 47887 situada perto da cabeça do Cone. A Nebulosa de Pele de Raposa é uma nebulosa de emissão que parece sobrepôr-se parcialmente em frente à nebulosa de reflexão azul, na região central da imagem.

Spaghetti Nebula – A Faint Reddish Supernova Remnant
A deep sky wide field view, captured in H-alpha and visible light (RGB) shows the extremely faint and large supernova remnant, Simeis 147 or Sharpless 2-240. Also known as Spaghetti Nebula, it is located near the border between the constellations of Taurus and Auriga, at a estimated distance of 3,000 light-years away from Earth. Spaning for more than 3 degrees across the sky, the reddish emission bubble from ionized hydrogen, features a debris cloud with a detailed complex of intricate filaments with about 150 light-years distance from edge to edge. The stellar explosion of this supernova may has occurred 40,000 years ago, lefting behind a spinning neutron star, known as pulsar PSR J0538+2817. Another small ionized HII nebula, SH2-242 (LBN 826) can be seen shinning in the lower right corner of the image. Captured from Cumeada Observatory, official headquarter of Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.

The Colorful Planetary Nebula Dumbbell M27
Captured in visible light, the image features the Dumbbell Nebula M27, a large and bright planetary Nebula and located at about about 1,200 light-years away in the constellation of Vulpecula. On July 12, 1764, it was discovered for the first time by french astronomer Charles Messier. On the center of the Nebula, lies an extremely hot white dwarf shinning at a magnitude of 13.5, being the largest known white dwarf, it illuminates the interstellar gas cloud with 2.5 light-years across. According to Nasa, the nebula forms as the star’s outer layers are expelled into space, with a visible glow generated by atoms excited by the dying star’s intense but invisible ultraviolet light. Captured in Cumeada Observatory from Dark Sky® Alqueva Reserve, Reguengos de Monsaraz, Portugal.

Rho Ophiuchi – A Wonderful Cosmic Cloud
The image features a close-up view of Rho Ophiuchi Cloud Complex, one of the most colourful nebulas in space and the closest star-forming regions to the Solar System, at an estimated distance of 460 light years. These interstellar clouds of gas and dust contain both red emission nebulas and blue reflection nebulas. The dark brown regions are caused by dust grains, born in young stellar atmospheres, which effectively block light emitted behind them. From the lower right corner, many dark absorption nebulas extends from the central band of our Milky Way Galaxy. Connecting the Pipe Nebula to the colourful region near bright star Antares, is a dark cloud known as “Dark River”, it can be identified as the brown dust lane connected to Antares, and spans about 100 light years. The distant globular cluster M4 is just seen at the left of the red supergiant star Antares, one of the brighter stars in the night sky, though it lies far behind the colourful cloud complex, at a distance of some 7,000 light-years.
PT: Nesta imagem é possível ver a brilhante estrela alaranjada Antares da constelação do Escorpião, no meio do complexo de Rho Ophiuchi, um dos complexos nebulosos mais coloridos do espaço e uma das regiões de formações de estrelas mais próximas ao sistema solar, localizado a uma distância estimada de 460 anos-luz, estas nuvens inter-estelares de gás e poeiras contêm nebulosas de emissão (vermelhas) e nebulosas de reflexão (azul). As regiões a castanho escuro são causadas por grãos de poeira, nascidos em atmosferas estelares jovens, que efetivamente bloqueiam a luz emitida por trás delas. No canto inferior direito, muitas nebulosas de absorção escura se estendem da banda central de nossa Galáxia, a Via Láctea, conectando a “Pipe Nebula” à região colorida perto da estrela brilhante Antares. Esta nebulosa escura é conhecida como “Dark River”, pode ser identificada como a banda de poeira castanha escura que está conectada à região de Antares e que se estende por 100 anos-luz de distância. O aglomerado globular M4 pode ser visto nesta imagem, à esquerda da estrela super gigante vermelha Antares, uma das estrelas mais brilhantes do céu noturno, este aglomerado está no entanto bem atrás do complexo colorido, a uma distância de cerca de 7.000 anos-luz.

The Great Orion Nebula – A Colourful Show in Visible Light
Captured in the “visible light”, the image shows a sharp and colourful view of the Great Orion Nebula. Also known as M42, is a diffuse and large nebula complex situated in the Milky Way, in the constellation of Orion. Located at a distance of about 1350 light years, Orion is estimated to be 24 light years across, being the closest region of massive star formation to Earth. This nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. The brightest central part of the nebula is called Huygenian region, and the Fish’s Mouth is the dark nebulosity that separates M43 from the bright part. Outside the edges of M42, we can also find the “Wings” of Orion. Due to the asterism of its primary four stars, the core of the nebula contains a very young open cluster known as the Trapezium, a cluster of newly formed stars shinning at the heart of the nebula. The red emission glows from the light of hydrogen gas excited by energetic newly-formed hot and young stars in the core of the nebula, but the blue-violet coloration, comes from the reflected radiation from the massive O-class stars. This complex contains dark nebulae, emission nebulae, reflection nebulae, and H II regions.
PT: Captada na banda da “luz visível”, a imagem revela uma visão nítida e colorida da Grande Nebulosa Orion. Também conhecida como M42, é um complexo nebuloso difuso muito grande situado na Via Láctea, na constelação de Orion. Localizado a uma distância de cerca de 1350 anos-luz, é a região mais próxima da Terra onde se formam estrelas maciças. Estima-se que o diâmetro da nebulosa M42 seja de aproximadamente 24 anos-luz. O estudo desta nebulosa já permitiu revelar muito sobre o processo de como as estrelas e os sistemas planetários são formados por nuvens de gás e poeira em colapso. A parte central mais brilhante da nebulosa é chamada região de Huygenian, e a “Fish’s Mouth” é a nebulosidade escura que separa M43 da parte mais brilhante da M42. Fora dos limites da M42 encontramos as “Asas” de Orion. O núcleo da nebulosa contém um aglomerado aberto muito jovem, conhecido como o Trapézio devido ao asterismo de suas quatro estrelas primárias. Duas destas podem ser resolvidas nos seus sistemas binários, em noites com boa visibilidade e estabilidade atmosférica, totalizando a soma de seis estrelas. As estrelas do Trapézio, conjuntamente com muitas outras estrelas do “berço estelar” que é a nebula de Orion, estão ainda nos seus primeiros anos de vida. A tonalidade avermelhada, é resultado de uma emissão brilhante a partir do gás de hidrogénio excitado por estrelas quentes e energéticas, recém-formadas no centro da nebulosa, mas a coloração azul-violeta visível na fotografia, provém da radiação refletida das estrelas da classe-O. Este complexo contém nebulosas escuras, nebulosas de emissão, nebulosas de reflexão e regiões H II.

The Wonderful Lagoon of Deep Space
The Lagoon Nebula also known as M8, is a magnificent complex of hot gas and dark nebulosity located in Sagittarius constellation. Shining at magnitude 5, and being below the limit capacity of human eye to distinguish faint objects in the night sky, M8 can be seen with the naked eye from a dark sky location. Inside the nebula, the energetic processes of star formation creates a huge chaos and a beautiful combination of colors. The red-glowing gas is resulting from high-energy starlight striking interstellar hydrogen. Hot young stars are forming in this stellar nursery. The dark dust filaments inside the nebula, were created in the atmospheres of cool giant stars and in the debris from supernovae explosions. Small dark knots, and globules that are condensing protostellar clouds are a sign that the process of star formation is still happening. The Lagoon Nebula gets its name from the distinctive dark lane that runs through the heart of the nebula. At the left side of this dark lane, is visible a bright star cluster known as NGC 6523. The Lagoon Nebula is so large, that is about 110 light-years across in space. It is located 5,000 light-years distant from us.
PT: A Nebulosa da Lagoa, também conhecida como M8, é um magnífico complexo de gás quente e nebulosidade escura localizado na constelação de Sagitário. Brilhando com uma magnitude de 5 e estando abaixo da capacidade limite do olho humano para distinguir objetos ténues no céu noturno, a M8 pode ser vista a olho nu a partir de um local com céu escuro. Dentro da nebulosa, os processos energéticos de formação de estrelas criam um enorme caos e uma combinação de cores ímpar. O gás vermelho-brilhante é resultante da luz estelar de alta energia que atinge o hidrogénio inter-estelar. Estrelas jovens e quentes formam-se assim neste berço estelar. Os filamentos de poeira escura dentro da nebulosa, foram criados nas atmosferas de estrelas gigantes e na sequência de explosões de supernovas. Os pequenos nódulos escuros que se espalham pela nebulosa estão condensando as nuvens proto-estelares, sendo um sinal de que o processo de formação estelar continua a ocorrer. A Nebulosa da Lagoa recebe esse nome devido à distinta faixa escura que atravessa o coração da nebulosa. No lado esquerdo desta faixa escura, é visível um aglomerado de estrelas brilhante conhecido como NGC 6523. A Nebulosa da Lagoa é tão grande, que tem cerca de 110 anos-luz de diâmetro no espaço. Está localizada a 5.000 anos-luz de nós..

The Colourful Spiral Galaxy of Andromeda
Homo is the genus that includes modern humans and their close relatives, originals habitants of planet Earth.The genus is estimated to be between 1.5 and 2.5 million years old. At approximately the same time, in space, the light from our neighboring galaxy Andromeda M31, has departed from the point in space where it is located, in the constellation of Andromeda. While the light from this source was travelling in the cold vacum of space at the speed of light, for the long journey of 2.5 million years, here in our planet, we have been evolved from the Homo Habilis up to the point where we have the necessary technology to construct powerful telescopes, giving us the capability to observing, studying, photographing and understanding the wonders of the vast Universe. Besides the huge distances, Andromeda galaxy is the nearest spiral galaxy to our Milky Way. With approximately 220,000 light-years across, Andromeda is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum galaxy, and about 30 other smaller galaxies. This colorful scene shows the arms and core of Andromeda immersed in several distinct stars that surrounding the diffuse spiral shape, are actually stars from our own galaxy, the Milky Way, well visible in front of M31. While its spiral arms stand out in visible light images, the arms look like rings in the GALEX ultraviolet views. Being sites of intense star formation, the rings have been interpreted as evidence that Andromeda collided with its smaller neighboring elliptical galaxy M32 more than 200 million years ago. M32 is also visible as the bright circular diffuse shape on the left side of the core. M110, a dwarf elliptical galaxy visible below M31, is also a satellite of the Andromeda Galaxy.
PT: Homo é o género que inclui os humanos modernos e seus parentes próximos, habitantes originários do planeta Terra. Este Género está estimado entre 1,5 e 2,5 milhões de anos. Aproximadamente ao mesmo tempo, no espaço, a luz da nossa galáxia vizinha Andromeda M31, partiu do ponto onde está localizada, na constelação de Andromeda. Enquanto a luz desta fonte viajava no vácuo frio do espaço à velocidade da luz, durante a longa jornada de 2,5 milhões de anos que nos separa, aqui no nosso planeta, evoluímos do Homo Habilis até ao ponto actual em que temos a tecnologia necessária para construir telescópios poderosos, dando-nos a capacidade de observar, estudar, fotografar e compreender as maravilhas do vasto universo. Apesar destas distâncias enormes, a galáxia de Andromeda é a galáxia espiral mais próxima da nossa galáxia, a Via Láctea. Com cerca de 220.000 anos-luz de diâmetro, Andromeda é a maior galáxia do Grupo Local, que também contém a Via Láctea, a galáxia de Triângulo, e cerca de 30 outras galáxias menores. A imagem mostra os braços e o núcleo de Andromeda imerso em várias estrelas distintas que circundam a sua forma espiral difusa. Estas estrelas são na verdade estrelas da nossa própria galáxia, a Via Láctea, visíveis em frente à M31 em pano de fundo. Enquanto seus braços espirais se destacam em imagens de luz visível, os braços parecem anéis quando visto no ultravioleta através do GALEX (Galaxy Evolution Explorer ). Sendo locais de intensa formação estelar, os anéis têm sido interpretados como evidência de que Andromeda colidiu com sua menor galáxia elíptica vizinha M32, há mais de 200 milhões de anos. M32 também é visível como a forma difusa circular brilhante no lado esquerdo do núcleo da M31. M110, uma galáxia elíptica anã visível abaixo de M31, é também um satélite da galáxia de Andromeda.

Comet 21p/Giacobini-Zinner Approaching Open Cluster M37
A rich starfield in Auriga constellation shows a close-up view of a bright tail and greenish coma from Comet 21P/Giacobini-Zinner only separated by approximately 1º from the colourful and brightest open cluster in Auriga, M37 (at right), with an apparent magnitude of 6.2, lies at a distance of 4,511 light years from our Solar System. On 10th September 2018, the comet Giacobini-Zinner was near its perihelion and closest approach to Earth in 72 years, being only at a distance of 58 million km from our planet, was shining like a 7th magnitude star, remaining too faint to our naked-eyes though. This periodic comet is the known parent body of the upcoming Draconid meteor shower, a bursty display that typically peaks on Oct. 8th. Draconid outbursts do tend to occur in years near the comet’s close approach to the sun. However, leading forecasters do not expect an outburst this year despite the comet’s flyby. The image was captured from Cumeada Observatory official headquarters of Dark Sky® Alqueva Reserve, Portugal.
PT: Um rico campo estelar na constelação de Auriga mostra uma visão de perto da cauda brilhante e coma esverdeado do Cometa 21P/Giacobini-Zinner, separado apenas por aproximadamente 1º do mais brilhante e colorido enxame aberto da Auriga, M37 (visível à direita), com uma aparente magnitude de 6,2, encontra-se a uma distância de 4.511 anos-luz do nosso Sistema Solar. Em 10 de setembro de 2018, o cometa Giacobini-Zinner encontrava-se perto de seu periélio, fazendo a sua máxima aproximação à Terra em 72 anos, ficando apenas a uma distância de 58 milhões de km de nosso planeta, brilhava como uma estrela de 7ª magnitude. Este cometa periódico é o corpo parente conhecido da próxima chuva de meteoros Dracónidas, uma chuva de meteoros que normalmente tem o seu pico no dia 8 de Outubro. As “Explosões de Dracónidas” tendem a ocorrer em anos que coincidem com a proximidade do cometa ao sol. No entanto, os cientistas não esperam uma explosão este ano, apesar da passagem do cometa por perto da Terra. A imagem e o Time Lapse, foram ambos captados no Observatório da Cumeada, sede oficial da Reserva Dark Sky® Alqueva.
Below, a short Time Lapse sequence of 3h captured on 14th September, shows the motion of the comet against the starry sky of Dark Sky Alqueva Reserve, Portugal.

NGC 1977 – A Running Man in Space
Popularly known as the Running Man Nebula and usually called NGC 1977, it actually comprises three NGC nebulae, NGC 1973, NGC 1975, and NGC 1977, forming a complex of blue reflection nebulae mixed with red emission nebulosity divided by dark lanes. Found just half a degree north of the bright stellar nursery better known as the Orion Nebula M42, these reflection nebulae are also associated with Orion’s giant molecular cloud, lying at a distance of about 1,500 light-years away, are dominated by a blue color of interstellar dust reflecting the light from hot young stars. The brightest nebulosity, later listed as NGC 1977, was discovered by William Herschel in 1786. Looking carefully to the center of the image (inside blue area), where dark regions laced with faint red emission from hydrogen atoms suggest to many, the shape of a running man.
PT: Popularmente designada como a nebulosa Running Man e geralmente reconhecida no seu todo como NGC 1977, na verdade compreende três nebulosas NGC diferentes, catalogadas como NGC 1973, NGC 1975 e NGC 1977, formando um complexo de nebulosas de reflexão azuis, divididas por faixas escuras de poeira densa que se misturam com uma nebulosidade de emissão vermelha. Encontrando-se apenas meio grau a norte de berço estelar brilhante, mais conhecido como Nebulosa de Orion M42, essas nebulosas de reflexão também estão associadas à gigante nuvem molecular de Orion, situada a uma distância de cerca de 1.500 anos-luz, são essencialmente compostas por uma tonalidade azulada proveniente da poeira inter-estelar que reflecte a luz de estrelas quentes e jovens. A nebulosidade mais brilhante, mais tarde catalogada como NGC 1977, foi descoberta por William Herschel em 1786. Olhando cuidadosamente para o centro da imagem, onde regiões escuras com fraca emissão vermelha de átomos de hidrogénio sugerem a muitos, a forma de um homem correndo.

Rho Ophiuchi – A Colourful Cloud in Space
Featuring the bright orange star Antares from Scorpius constellation, Rho Ophiuchi Cloud Complex is one of the most colourful nebulas in space and the closest star-forming regions to the Solar System, at an estimated distance of 460 light years.These interstellar clouds of gas and dust contain both red emission nebulas and blue reflection nebulas. The dark brown regions are caused by dust grains, born in young stellar atmospheres, which effectively block light emitted behind them. From the lower left corner, many dark absorption nebulas extends from the central band of our Milky Way Galaxy. Connecting the Pipe Nebula to the colourful region near bright star Antares, is a dark cloud known as “Dark River”, it can be identified as the brown dust lane connected to Antares, and spans about 100 light years. Since the Dark River dust lane lies only about 500 light years away, it only appears as a bridge to the much more distant Galactic Center, that actually lies about 25,000 light years farther away. The distant globular cluster M4 is just seen at the right of the red supergiant star Antares, one of the brighter stars in the night sky, though it lies far behind the colourful cloud complex, at a distance of some 7,000 light-years.
PT: Nesta imagem é possível ver a brilhante estrela alaranjada Antares da constelação do Escorpião, no meio do complexo de Rho Ophiuchi, um dos complexos nebulosos mais coloridos do espaço e uma das regiões de formações de estrelas mais próximas ao sistema solar, localizado a uma distância estimada de 460 anos-luz, estas nuvens inter-estelares de gás e poeiras contêm nebulosas de emissão (vermelhas) e nebulosas de reflexão (azul). As regiões a castanho escuro são causadas por grãos de poeira, nascidos em atmosferas estelares jovens, que efetivamente bloqueiam a luz emitida por trás delas. No canto inferior esquerdo, muitas nebulosas de absorção escura se estendem da banda central de nossa Galáxia, a Via Láctea, conectando a “Pipe Nebula” à região colorida perto da estrela brilhante Antares. Esta nebulosa escura é conhecida como “Dark River”, pode ser identificada como a banda de poeira castanha escura que está conectada à região de Antares e que se estende por 100 anos-luz de distância. O aglomerado globular M4 pode ser visto à direita da estrela super gigante vermelha Antares, uma das estrelas mais brilhantes do céu noturno, este aglomerado está no entanto bem atrás do complexo colorido, a uma distância de cerca de 7.000 anos-luz.

Heart Nebula, When the Universe Falls in Love
The beautiful Heart Nebula also known as IC 1805, is an emission nebula that have the shape of a human heart showing glowing ionized hydrogen gas and darker dust lanes. Lying at about 7500 light years away from Earth, is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. The very brightest part of this nebula (the knot at the right edge) is separately classified as NGC 896, because it was the first part of this nebula to be discovered. The nebula’s intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula’s center. This open cluster of stars known as Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun’s mass.
PT: A bela Nebulosa do Coração também conhecida como IC 1805, é uma nebulosa de emissão que tem a forma de um coração humano, revelando o brilho do hidrogénio ionizado e faixas de poeira mais escuras. Situada a cerca de 7500 anos-luz da Terra, está localizada no Braço de Perseus da nossa Galáxia, mais precisamente na constelação Cassiopeia. A parte mais brilhante desta nebulosa (o nó na borda direita) é classificado separadamente como NGC 896, porque foi a primeira parte desta nebulosa a ser descoberta. A intensa emissão vermelha da nebulosa e a sua configuração são impulsionadas pela radiação que emana de um pequeno grupo de estrelas perto do centro da nebulosa. Este conjunto aberto de estrelas conhecido como Melotte 15, contém algumas estrelas brilhantes com quase 50 vezes a massa do nosso Sol, e muitas mais estrelas fracas que são apenas uma fração da massa do nosso Sol.

The Trifid Nebula Between a Colorful Ocean of Stars
The Trifid Nebula (M20 and NGC 6514) lies 5200 light-years away and is an H II region located in the constellation of Sagittarius. It was discovered by Charles Messier on June 5, 1764. Its name means ‘divided into three lobes’. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula which forms the three prominent dust lanes, also knwon as Barnard 85. The Trifid is only 300,000 years old and is a star forming region in the Scutum spiral arm of the Milky Way. A hot young star in the center illuminates the nebula. The most massive star that has formed in this region is HD 164492A, an O7.5III star with a mass more than 20 times the mass of the Sun. This star is surrounded by a cluster of approximately 3100 young stars.
PT: A Nebulosa Trífida (M20 e NGC 6514) fica a 5200 anos-luz de distância e é uma região H II, ou seja, composta de gás e poeira estelar onde recentemente se começaram a formar novas estrelas, e está localizada na constelação de Sagitário. Foi descoberta por Charles Messier em 5 de junho de 1764. Seu nome significa “dividido em três lóbulos”. O objeto é uma combinação incomum de um aglomerado aberto de estrelas; Uma nebulosa de emissão (parte inferior vermelha), uma nebulosa de reflexão (parte superior azul) e uma nebulosa escura que forma as três faixas proeminentes de poeiras escuras, catalogada como Barnard 85 (B85) por Edward Barnard. A Trífida tem apenas 300.000 anos de idade e está localizada na região Scutum no braço espiral da Via Láctea. Uma estrela jovem e quente no centro ilumina a nebulosa. A estrela mais maciça que se formou nesta região é HD 164492A, uma estrela O7.5III com uma massa de mais de 20 vezes superior à do sol. Esta estrela está cercada por um conjunto de aproximadamente 3100 jovens estrelas.

The Dusty Shiny Heart of Orion
The Orion Nebula (M42) is a diffuse and large nebula complex situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion, is one of the brightest and beautiful nebulae also visible to naked eye in the night sky. M42 is located at a distance of about 1350 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. This nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.
The brightest central part of the nebula is called Huygenian region, and the Fish’s Mouth is the dark nebulosity that separates M43 from the bright part. Outside the edges of M42 we can find the “Wings” of Orion. The core of the nebula contains a very young open cluster, known as the Trapezium due to the asterism of its primary four stars. Two of these can be resolved into their component binary systems on nights with good seeing, giving a total of six stars. The stars of the Trapezium, along with many other stars, are still in their early years.
Observers have long noted a distinctive greenish tint to the nebula, in addition to regions of red and of blue-violet. The red hue is a result of the Hα recombination line radiation at a wavelength of 656.3 nm. This red emission glows from the light of hydrogen gas excited by energetic newly-formed hot and young stars in the core of the nebula. The blue-violet coloration is the reflected radiation from the massive O-class stars in the heart of the nebula. This complex contains dark nebulae, emission nebulae, reflection nebulae, and H II regions.
NGC 1977 is a reflection nebula 1/2 degree northeast of the Orion Nebula. This NGC nebula also includes NGC1973 and NGC1975, divided as a complex of blue reflection nebulae mixed with dark lanes and a red emission nebulosity. It is also called The Running Man Nebula and Sharpless Catalog 279. More about
PT: A Nebulosa de Orion (M42) é um grande complexo nebuloso difuso situado na Via Láctea, a sul do Cinturão de Orion na constelação de Orion, sendo também uma das mais brilhantes e fascinantes nebulosas visíveis a olho nu no céu noturno. M42 está localizado a uma distância de cerca de 1350 anos-luz e é a região mais próxima da Terra na formação de estrelas maciças. A nebulosa M42 está estimada em 24 anos-luz de diâmetro. Tem uma massa de cerca de 2000 vezes a massa do Sol. O estudo desta nebulosa já permitiu revelar muito sobre o processo de como as estrelas e os sistemas planetários são formados por nuvens de gás e poeira em colapso. Os astrónomos observaram directamente discos protoplanetários, anãs castanhas, movimentos intensos e turbulentos de gás e os efeitos foto-ionizantes de estrelas maciças próximas, na nebulosa.
A parte central mais brilhante da nebulosa é chamada região de Huygenian, e a “Fish’s Mouth” é a nebulosidade escura que separa M43 da parte mais brilhante da M42. Fora dos limites da M42 encontramos as “Asas” de Orion. O núcleo da nebulosa contém um aglomerado aberto muito jovem, conhecido como o Trapézio devido ao asterismo de suas quatro estrelas primárias. Duas destas podem ser resolvidas nos seus sistemas binários, em noites com boa visibilidade e estabilidade atmosférica, totalizando a soma de seis estrelas. As estrelas do Trapézio, conjuntamente com muitas outras estrelas, estão ainda nos seus primeiros anos de vida.
Além de regiões de tonalidade vermelha e azul-violeta, tem-se observado desde há muito tempo um matiz esverdeado distinto nalgumas regiões da nebulosa. A tonalidade vermelha é explicada pela emissão de uma combinação de linhas de radiação do hidrogênio, Hα, com um comprimento de onda de 656,3 nanómetros. A cor azul-violeta é o reflexo da radiação das estrelas de tipo espectral O (muito luminosas e de cores azuladas) sobre o centro da nebulosa. Este complexo contém nebulosas escuras, nebulosas de emissão, nebulosas de reflexão e regiões H II.
NGC 1977 é uma nebulosa de reflexão 1/2 grau a nordeste (à esquerda na imagem) da Nebulosa de Orion. Esta nebulosa NGC inclui também a NGC1973 e NGC1975, dividindo-se assim como um complexo de nebulosas de reflexão azuis, misturadas com nebulosas escuras e uma nebulosidade de emissão vermelha. É também chamado de “The Running Man Nebula”.

The Dust of Pleiades Star Cluster and a Faint Spiral Galaxy
The Pleiades, or Seven Sisters (Messier 45 or M45), is an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The cluster contains 1,000 stars, of which more than a dozen can be seen with the unaided eye. The celestial entity has several meanings in different cultures and traditions.
The blue nebulosity that surrounds the cluster is a reflection nebula. The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years, and are located 391 light-years away according to measurements made by the Hipparcos satellite. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.
In the same field of view and less obvious than the brightest hot stars from Pleiades, near the star Electra, can be seen a very faint spiral galaxy UGC 2838 (PGC13696) with a magnitude of 17.8, is beyond the limit of our human capacity to distinguish faint objects and is in the limit detection of many small optical instruments. The named members of the Pleiades and their magnitudes are: Pleione – 5.2 | Atlas – 3.8 | Alcyone – 3.0 | Merope – 4.3 | Electra – 3.8 | Celaeno – 5.4 | Taygeta – 4.4 | Maia – 4.0 | Sterope – 5.9
PT: As Plêiades, ou Sete Irmãs (Messier 45 ou M45), é um aglomerado de estrelas aberto contendo estrelas de meia-idade, tipo B quentes, localizadas na constelação do Touro. Está entre os aglomerados de estrelas mais próximos da Terra e é o aglomerado mais óbvio a olho nu no céu noturno. Este cluster, contém cerca de 1000 estrelas das quais mais de uma dúzia podem ser vistas a o olho nu para um observador experiente e com boa acuidade visual. Este objecto celeste tem vários significados em diferentes culturas e tradições.
A nebulosidade azul que circunda o cluster é uma nebulosa de reflexão. O cluster é dominado por estrelas azuis quentes e extremamente luminosas que se formaram nos últimos 100 milhões de anos e estão localizadas a 391 anos-luz de distância da Terra de acordo com as medições feitas pelo satélite Hipparcos. Pensava-se inicialmente que a poeira que forma uma tênue nebulosidade de reflexão em torno das estrelas mais brilhantes teria sido consequência da formação do aglomerado, mas agora é conhecida por ser uma nuvem de poeira Interstelar não relacionada, pela qual as estrelas estão a atravessar atualmente. As simulações de computador mostraram que as Plêiades provavelmente foram formadas a partir de uma configuração compacta que se assemelhava à Nebulosa de Orion. Os astrónomos estimam que o cluster irá sobreviver por cerca de mais 250 milhões de anos, após o que se dispersará devido às interações gravitacionais com sua vizinhança galáctica.
No mesmo campo de visão e menos óbvio que as estrelas quentes mais brilhantes de Pleiades, perto da estrela Electra, pode ser vista uma galáxia espiral muito fraca UGC 2838 (PGC13696) com uma magnitude de 17,8 está além do limite de detecção da nossa capacidade humana para distinguir objetos fracos e no limite de detecção de muitos instrumentos ópticos mais pequenos.
As principais estrelas das Plêiades e suas magnitudes aparentes são: Pleione – 5.2 | Atlas – 3,8 | Alcyone – 3.0 | Merope – 4.3 | Electra – 3.8 | Celaeno – 5.4 | Taygeta – 4.4 | Maia – 4.0 | Sterope – 5,9

Rosette Nebula, When a Flower Gives Birth in Space
The Rosette Nebula is a large complex of bright emission and dark nebulae, located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster in the center, NGC 2244, is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s matter. Scientists conclude that the central cluster formed first, followed by expansion of the nebula, which triggered the formation of the neighboring clusters, including NGC 2237. The cluster and nebula lie at a distance of some 5,000 light-years from Earth and the center hole measure roughly 50 light years in diameter. Stellar winds from these hot young stars has cleared out the cavity in the center of the nebula. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the redish color of an hydrogen-alpha emission. The mass of the nebula is estimated to be around 10,000 solar masses.
A survey of the nebula with the Chandra X-ray Observatory has revealed the presence of numerous new-born stars inside optical Rosette Nebula and studded within a dense molecular cloud. Altogether, approximately 2500 young stars lie in this star-forming complex,The X-rays reveal hundreds of young stars clustered in the center of the image and additional fainter clusters on either side. The study of the cluster provides the first probe of the low-mass stars in this satellite cluster. The presence of several X-ray emitting stars around the pillars and the detection of an outflow — commonly associated with very young stars — originating from a dark area of the optical image indicates that star formation is continuing in NGC 2237.
The dark nebulae are part of a complex of Bok globules inside the Rosette Nebula. Bok Globules are dense opaque clouds of gas and dust, some of which are condensing under gravitational attraction to form stars and planets. Bok globules were first seen and observed by astronomer Bart Bok in the 1940s.
PT: A Nebulosa da Roseta é um grande complexo de emissão brilhante e de nebulosas escuras, localizado perto de uma extremidade de uma nuvem molecular gigante na região de Monoceros, na Via Láctea. O aglomerado aberto ao centro, NGC 2244, está intimamente associado à nebulosidade tendo as estrelas do aglomerado sido formadas a partir da matéria da nebulosa. Os cientistas concluem que o aglomerado central se formou primeiro, seguido pela expansão da nebulosa, o que desencadeou a formação dos aglomerados vizinhos, incluindo o NGC 2237. O aglomerado e a nebulosa ficam a uma distância de cerca de 5.000 anos-luz da Terra e a medida da cavidade central é de cerca de 50 anos-luz de diâmetro. Os ventos estelares destas estrelas jovens e quentes apagaram a cavidade no centro da nebulosa. A radiação das estrelas jovens excita os átomos na nebulosa, fazendo com que eles emitam radiação produzindo a cor avermelhada, uma emissão de hidrogénio-alfa. A massa da nebulosa está estimada em cerca de 10.000 massas solares.
Um estudo recente da nebulosa com o Observatório Chandra de raios-X, revelou a presença de numerosas estrelas recém-nascidas dentro da nebulosa óptica Rosette e studded dentro de uma nuvem molecular densa. Ao todo, aproximadamente 2500 estrelas novas encontram-se neste complexo de formação de estrelas, os raios X revelam centenas de estrelas novas agrupadas no centro da imagem e em uns conjuntos mais pequenos de cada lado. As nebulosas escuras são parte de um complexo de “Bok Globules” dentro da Nebulosa Roseta. Bok Globules são densas nuvens opacas de gás e poeira, algumas das quais estão a condensar-se sob atração gravitacional para formar estrelas e planetas. Os “glóbulos de Bok” foram vistos pela primeira vez e observados pelo astrónomo Bart Bok na década de 1940.
