Zodiacal Light from Dark Sky® Vale do Tua
Captured from Ansiães Castle, in Tua Valley, territory of Dark Sky Vale do Tua, in the northern part of Portugal, the image shows the Zodiacal Light – a very faint diffuse light coming from the region where planet Venus was located in the eastern sky visible at dawn few minutes before the sunrise.The zodiacal light is a faint light beam that extends along the ecliptic plane, where are the constellations of the Zodiac. It is caused by the scattering of sunlight in cosmic dust particles that can be found scattered all over the Solar System. Following the faint shape which crossed almost the entire vertical panorama, we can see the Beehive cluster in the upper right corner.
PT: Captada dentro do Castelo de Ansiães, em Carrazeda de Ansiães, território do Dark Sky® Vale do Tua, no norte de Portugal, a imagem mostra a Luz Zodiacal – uma luz difusa muito ténue proveniente da região onde se localizava o planeta Vénus no céu oriental visível ao amanhecer, poucos minutos antes do nascer do sol. A luz zodiacal é um feixe de luz ténue que se estende ao longo do plano da eclíptica, onde estão as constelações do Zodíaco. É causada pela dispersão da luz solar em partículas de poeira cósmica que podem ser encontradas espalhadas por todo o Sistema Solar. Seguindo a forma ténue que cruza quase todo o panorama vertical, podemos ver o aglomerado de colmeia no canto superior direito.

Gengenschein, Airglow and Winter Milky Way above Zêzere River
Captured recently from Pampilhosa da Serra, in the heart of a new starlight destination created in center of Portugal, called Dark Sky Aldeias do Xisto, the image shows the winter arch of our Milky Way galaxy shining above the mountains of Pampilhosa, while in the top left a Gengenschein phenomenon is visible as the faint light behind the Beehive star cluster, located in the antisolar point, is the backscatter of sunlight by the interplanetary dust. In the left edge, bands of reddish airglow are visible above the curved arm of Zêzere river..
PT: Captada recentemente na Pampilhosa da Serra, no coração de um novo destino Starlight criado no centro de Portugal, chamado Dark Sky Aldeias do Xisto, a imagem revela o arco de inverno da nossa galáxia, a Via Láctea, brilhando sobre as montanhas da Pampilhosa, enquanto no canto superior esquerdo é visível o fenómeno Gengenschein. Trata-se de uma emissão de luz muito ténue perceptível atrás do aglomerado de estrelas da Colmeia, localizado no ponto anti-solar, é a retro dispersão da luz solar pela poeira interplanetária. Na margem esquerda, faixas de airglow avermelhado são visíveis acima do braço curvo do rio Zêzere.
A Strong Zodiacal Light and Winter Milky Way Shines above Pampilhosa da Serra
Captured recently from Pampilhosa da Serra at the end of twilight, in the heart of a new starlight destination created in center of Portugal, called Dark Sky Aldeias do Xisto, the image shows the strongest Zodiacal Light I´ve ever photographed – which could be even seen with naked eye – as a very very faint diffuse light coming from the region where planet Venus was located in the western sky. The zodiacal light is a faint light beam that extends along the ecliptic plane, where they are the constellations of the Zodiac. It is caused by the scattering of sunlight in cosmic dust particles that can be found scattered all over the Solar System. Following the faint shape which crossed almost the entire vertical panorama comprising 4 still images, and will end up on the Pleiades blueish star cluster. Above it, a beautiful winter Milky Way was arching and shining near the Zenith, featuring winter deep sky wonders like California nebula (on the top right of Pleiades) or the Heart and Soul reddish nebulosity in the right edge of the image. Below the deep sky pair, an oblong diffuse shape is also visible, belonging to our neighbour Galaxy of Andromeda. On the ground, between the mountain range of Pampilhosa, curving channels from the lake of Santa Luzia dam, are reflecting the strong light of Venus, as well as the less colorful hues from the end of nautical twilight.
PT: Captada recentemente na Pampilhosa da Serra ao final do crepúsculo, no coração de um novo destino Starlight criado no centro de Portugal, chamado Dark Sky Aldeias do Xisto, a imagem mostra a Luz Zodiacal mais forte que já tive oportunidade de fotografar até hoje e que podia ser vista a olho nu, como uma luz difusa muito fraca, proveniente da região ocidental do céu onde o planeta Vénus se encontrava. A luz Zodiacal é um feixe de luz fraca que se estende ao longo do plano da eclíptica, onde estão as constelações do zodíaco. É causada pela dispersão da luz solar nas partículas de poeira cósmica que se podem encontrar espalhadas um pouco por todo o Sistema Solar. Seguindo a emissão ténue que atravessa quase todo o panorama vertical, composto por 4 imagens estáticas, encontramos o aglomerado de estrelas jovens, quentes e azuladas, Pleaides (M45). Acima deste, uma bela Via Láctea de inverno arqueada brilhava perto Zénite, apresentando as maravilhas do céu profundo como a nebulosa da Califórnia (no centro superior, à direita das Pleiades) ou a nebulosidade avermelhada do Coração e da Alma, no extremo direita da imagem. Abaixo deste par de céu profundo, também é visível uma forma difusa oblonga, pertencente à nossa vizinha Galáxia de Andrómeda. Na paisagem, por entre a cordilheira de Pampilhosa, canais em curva pertencentes ao lago da barragem de Santa Luzia, reflectem a forte luz de Vénus, bem como os tons suvamente esbatidos do final do crepúsculo náutico.
Zodiacal Light and Winter Constellations above Pulo do Lobo
A night scene captured in Pulo do Lobo, Dark Sky® Alqueva Mértola, shows a view of the winter Milky Way full of deep sky objects shinning bright with a diffuse red/violet colors. From top right corner to the bottom, we can find California nebula and Pleiades, a bright blueish star cluster, while below is visible all the reddish emission coming from Orion, with Lambda Orionis, Barnard´s Loop, Horse Head and M42 nebulae surrounding the main brightest stars of Orion constellation. At the left side not far away from Orion, a violet emission is shinning from Rosette nebula. At left edge of the image and above the horizon is visible a faint white light that seems to point to Beehive star cluster, known as Zodiacal light, is the sunlight scattered by interplanetary dust. Most of this dust is orbiting the Sun in about the ecliptic plane.
Pulo do Lobo is the most dramatic stretch of Guadiana River, located about 18 kms north of Mértola, where the Guadiana river bed is reduced to a narrow strait a few meters wide, followed by a small waterfall with about 4m high. The margins on this site are tall and stony, and so tight that they have given rise to a legend that says that a wolf in hunting could transports them in a jump.
PT: Este cenário nocturno captado no Pulo do Lobo, na Reserva Dark Sky® Alqueva Mértola, mostra uma visão da Via Láctea de inverno repleta de objectos do céu profundo que se destacam com tonalidades difusas vermelho/violeta ao longo do caminho descrito pela nossa galáxia. Do topo direito em direcção ao horizonte, é possível ver a Nebulosa da Califórnia e à direita as Pleiades, um aglomerado estelar azul brilhante. Logo abaixo é visível toda a emissão avermelhada proveniente de Orion, com diversos objectos como Lambda Orionis, Barnard´s Loop, Horse Head e a nebulosa M42 circundando as principais estrelas brilhantes da constelação de Orion. No lado esquerdo, não longe de Orion, a nebulosa da Roseta é visível como uma emissão violeta brilhante. No extremo esquerdo da imagem e logo acima do horizonte, uma fraca emissão esbranquiçada que parece incidir na direcção do aglomerado estelar Beehive, é conhecida como a Luz Zodiacal. Trata-se da luz solar dispersa pela poeira interplanetária. A maior parte dessa poeira está orbitando o Sol em torno do plano eclíptico.
O Pulo do Lobo é o mais dramático trecho do rio Guadiana, situado a cerca de 18 kms a Norte de Mértola, onde o leito do rio Guadiana fica reduzido a um estreito rápido com poucos metros de largura, seguido de uma pequena queda de água com cerca de 4m de altura. As margens neste local apresentam-se altas e pedregosas, e tão apertadas que deram origem a uma lenda que afirma que um lobo em caça as transpõe em um salto.
A Strong Gegenschein Between the Winter Constellations
A night scene captured in Pulo do Lobo, Dark Sky® Alqueva Mértola, shows a path of light from the winter Milky Way full of bright stars like the ones that are composing the constellations of Orion. Above the horizon, Sirius is the brightest star that dominates the night, but due to the little presence of haze, stars like Pollux and Castor from Gemini constellation are also showing their beautiful natural colors. But between Procyon, Castor and Betelgeuse, near the Zenith spotted in the center of the image, is noticeable a rare and faint white light known as Gegenschein, that is a faint brightening of the night sky in the region of the antisolar point. like the zodiacal light, the gegenschein is sunlight scattered by interplanetary dust. Most of this dust is orbiting the Sun in about the ecliptic plane. It is distinguished from zodiacal light by its high angle of reflection of the incident sunlight on the dust particles.
PT: Uma cena nocturna captada no Pulo do Lobo, Dark Sky® Alqueva Mértola, mostra o ténue caminho de luz da Via Láctea invernal repleto de estrelas brilhantes como as que compõem as constelações de Orion. Acima do horizonte, Sirius é a estrela mais brilhante que domina a noite, mas devido à pequena presença de neblina, estrelas como Pollux e Castor da constelação de Gémeos também mostram suas lindas cores naturais. No entanto, entre Procyon, Castor e Betelgeuse, perto do Zénite, localizado no centro da imagem, é possível percepcionar uma luz branca rara e fraca, conhecida como Gegenschein, que é um leve brilho do céu noturno na região do ponto antissolar. Tal como a luz Zodiacal, a Gegenschein é a luz solar espalhada pelo poeira interplanetária. A maior parte desta poeira está orbitando o Sol em aproximadamente o plano da Eclíptica. Distingue-se da luz Zodiacal pelo seu alto ângulo de reflexão da luz solar incidente sobre as partículas de poeira.

Zodiacal light in the glacial valley of Glendalough
Zodiacal light and planet Venus in the forest of Glendalough. Meaning “Valley of two lakes”, is a glacial valley in County Wicklow, Ireland, renowned for an Early Medieval monastic settlement founded in the 6th century by St Kevin. It combines extensive monastic ruins with a stunning natural setting in the Wicklow Mountains. The beauty and tranquility of the lakes and glacial-carved valley no doubt appealed to St Kevin, a hermit monk, who founded the monastic site near the Lower Lake in the 6th Century. Most of the buildings that survive today date from the 10th through 12th centuries. Despite attacks by Vikings over the years, Glendalough thrived as one of Irelands great ecclesiastical foundations and schools of learning until the Normans destroyed the monastery in 1214 and the dioceses of Glendalough and Dublin were united. The settlement was destroyed by English forces in 1398. A reconstruction program was started in 1878 and today the valley boasts a visitor centre, wooded trails, walkways and rock climbing. The monastic ruins include a round tower, seven churches, a gateway into the settlement with a Sanctuary Stone, two High Crosses, the priest’s house, a graveyard, Reeferts Church, St. Kevin’s Bed (Cave) and St. Kevin’s Cell (hermitage hut). More about.
PT: Luz zodiacal e o planeta Vénus na floresta de Glendalough. Com o significado “Vale dos dois lagos”, é um vale glacial no condado de Wicklow, na Irlanda, conhecida por uma povoação monástica medieval precoce fundada no século 6 pelo St Kevin. Combina extensas ruínas monásticas com um cenário natural deslumbrante nas montanhas de Wicklow. A beleza e tranquilidade dos lagos e do vale glacial esculpido, sem dúvida, chamaram a atenção do monge eremita St Kevin . A maioria dos edifícios que sobreviveram até aos dias de hoje datam do século 12. Apesar dos ataques de Vikings ao longo dos anos, Glendalough prosperou como uma das grandes fundações eclesiásticas irlandesas e escolas de aprendizagem até que os normandos destruiram o mosteiro em 1214 e as dioceses de Glendalough e Dublin foram unidos. A liquidação foi destruída por forças inglesas em 1398. Um programa de reconstrução foi iniciado em 1878 e hoje o vale dispõe de um centro de visitantes, trilhas arborizadas, calçadas e escalada. As ruínas monásticas incluem uma torre redonda, sete igrejas, uma porta de entrada para a povoação com um Santuário de pedra, duas cruzes celtas altas, casa do padre e um cemitério.

The Arc of Milky Way in the Twilight with the Moon and Zodiacal Light above VLT
The entire Arc of Milky Way full of gas and dust can be seen in this panoramic lovely view from the southern sky, captured in the end of nautical twilight, above the Very Large Telescope platform. At left of the small tower, above the horizon, the bright object visible is not a star itself, but the great globular cluster Omega Centauri. Closer to left in the beginning of Milky Way arc, are spotted the bright stars of Alpha and Beta Centauri. In the middle of the image, the strong light of crescent moon is shining above the Antu telescope, the first one. Above the moon, we can see the planet Saturn, the orange star Antares from Scorpius constellation, and the dark streaks that are part of Rho Ophiuchi cloud complex, which connects this region to the main arm of Milky Way with more then 200º from side to side. In the background of this same region, a faint white light is visible, called the Zodiacal Light. In the foreground at right, we can see the Yepun telescope, reflecting a silver color coming from the moon reflection on its metallic surface. In the extremely right edge of the image, the Andromeda galaxy is even visible as an elongated diffuse dot.
The Very Large Telescope (VLT) is a telescope operated by the ESO – European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. The VLT is the world’s most advanced optical instrument, consisting of four Unit Telescopes with main mirrors of 8.2m diameter, which are generally used separately but can be used together to achieve very high angular resolution. The four separate optical telescopes are known as Antu, Kueyen, Melipal and Yepun, which are all words for astronomical objects in the Mapuche language, with optical elements that can combine them into an astronomical interferometer (VLTI), which is used to resolve small objects. The interferometer is complemented by four movable Auxiliary Telescopes (ATs) of 1.8 m aperture. The 8.2m diameter Unit Telescopes can also be used individually. With one such telescope, images of celestial objects as faint as magnitude 30 can be obtained in a one-hour exposure. This corresponds to seeing objects that are four billion (four thousand million) times fainter than what can be seen with the unaided eye. The telescopes can work together, to form a giant ‘interferometer’, the ESO Very Large Telescope Interferometer, allowing astronomers to see details up to 25 times finer than with the individual telescopes. The light beams are combined in the VLTI using a complex system of mirrors in underground tunnels where the light paths must be kept equal to distances less than 1/1000 mm over a hundred metres. With this kind of precision the VLTI can reconstruct images with an angular resolution of milliarcseconds, equivalent to distinguishing the two headlights of a car at the distance of the Moon.

Reddish Airglow Bands on ALMA sky
In the background, we can see the arm of Milky Way full of gas and dust with the Zodiacal Light crossing the sky. In the upper left part of the image, is also visible a reddish airglow bands. In the foreground, is also visible one antenna (DV-21) of 12 meters in diameter, pointing to some place of the cold Universe. This are the first tests to experiment the largest configuration that ALMA can support, with antennas spreaded over distances up to 16 km. The array thus simulates a giant, single telescope much larger than any that could actually be built. In fact, ALMA has a maximum resolution which is even better than that achieved, at visible wavelengths, by the Hubble Space Telescope.
The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of radio telescopes in the Atacama desert of northern Chile. Since a high and dry site is crucial to millimeter wavelength operations, the array has been constructed on the Chajnantor plateau at 5,000 meters altitude, near Llano de Chajnantor Observatory and Atacama Pathfinder Experiment. Consisting of 66 12-meter (39 ft), and 7-meter (23 ft) diameter radio telescopes observing at millimeter and submillimeter wavelengths, ALMA is expected to provide insight on star birth during the early universe and detailed imaging of local star and planet formation. ALMA is a single telescope of revolutionary design, composed initially of 66 high-precision antennas, and operating at wavelengths of 0.32 to 3.6 mm. Its main 12-metre array has fifty antennas, 12 metres in diameter, acting together as a single telescope — an interferometer. An additional compact array of four 12-metre and twelve 7-metre antennas complements this. The 66 ALMA antennas can be arranged in different configurations, where the maximum distance between antennas can vary from 150 metres to 16 kilometres, which will give ALMA a powerful variable “zoom”. It will be able to probe the Universe at millimetre and submillimetre wavelengths with unprecedented sensitivity and resolution, with a vision up to ten times sharper than the Hubble Space Telescope, and complementing images made with the VLT Interferometer. Light at these wavelengths comes from vast cold clouds in interstellar space, at temperatures only a few tens of degrees above absolute zero, and from some of the earliest and most distant galaxies in the Universe. Astronomers can use it to study the chemical and physical conditions in molecular clouds — the dense regions of gas and dust where new stars are being born. Often these regions of the Universe are dark and obscured in visible light, but they shine brightly in the millimetre and submillimetre part of the spectrum. ALMA is the most powerful telescope for observing the cool Universe — molecular gas and dust.
ALMA will study the building blocks of stars, planetary systems, galaxies and life itself. By providing scientists with detailed images of stars and planets being born in gas clouds near our Solar System, and detecting distant galaxies forming at the edge of the observable Universe, which we see as they were roughly ten billion years ago, it lets astronomers address some of the deepest questions of our cosmic origins.

AllSky of VLT Yepun
In the background of this fish-eye fulldome picture, at the left side of Yepun VLT Telescope, we can see the Large and Small Magellanic Clouds, while in center right of the image, the Zodiacal Light is coming up above the Milky Way that is lying behind the horizon.
The Very Large Telescope (VLT) is a telescope operated by the ESO – European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. The VLT is the world’s most advanced optical instrument, consisting of four Unit Telescopes with main mirrors of 8.2m diameter, which are generally used separately but can be used together to achieve very high angular resolution. The four separate optical telescopes are known as Antu, Kueyen, Melipal and Yepun, which are all words for astronomical objects in the Mapuche language, with optical elements that can combine them into an astronomical interferometer (VLTI), which is used to resolve small objects. The interferometer is complemented by four movable Auxiliary Telescopes (ATs) of 1.8 m aperture. The 8.2m diameter Unit Telescopes can also be used individually. With one such telescope, images of celestial objects as faint as magnitude 30 can be obtained in a one-hour exposure. This corresponds to seeing objects that are four billion (four thousand million) times fainter than what can be seen with the unaided eye. The telescopes can work together, to form a giant ‘interferometer’, the ESO Very Large Telescope Interferometer, allowing astronomers to see details up to 25 times finer than with the individual telescopes. The light beams are combined in the VLTI using a complex system of mirrors in underground tunnels where the light paths must be kept equal to distances less than 1/1000 mm over a hundred metres. With this kind of precision the VLTI can reconstruct images with an angular resolution of milliarcseconds, equivalent to distinguishing the two headlights of a car at the distance of the Moon.

Fulldome View of Reddish Airglow Bands and Milky Way on ALMA
In the background, we can see in this fish-eye fulldome view, the arm of Milky Way full of gas and dust with the Zodiacal Light crossing the sky. In the upper left part of the image, is also visible a reddish airglow bands. In the foreground, is also visible one antenna (DV-21) of 12 meters in diameter, pointing to some place of the cold Universe. This are the first tests to experiment the largest configuration that ALMA can support, with antennas spread over distances up to 16 km. The array thus simulates a giant, single telescope much larger than any that could actually be built. In fact, ALMA has a maximum resolution which is even better than that achieved, at visible wavelengths, by the Hubble Space Telescope.
The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of radio telescopes in the Atacama desert of northern Chile. Since a high and dry site is crucial to millimeter wavelength operations, the array has been constructed on the Chajnantor plateau at 5,000 meters altitude, near Llano de Chajnantor Observatory and Atacama Pathfinder Experiment. Consisting of 66 12-meter (39 ft), and 7-meter (23 ft) diameter radio telescopes observing at millimeter and submillimeter wavelengths, ALMA is expected to provide insight on star birth during the early universe and detailed imaging of local star and planet formation. ALMA is a single telescope of revolutionary design, composed initially of 66 high-precision antennas, and operating at wavelengths of 0.32 to 3.6 mm. Its main 12-metre array has fifty antennas, 12 metres in diameter, acting together as a single telescope — an interferometer. An additional compact array of four 12-metre and twelve 7-metre antennas complements this. The 66 ALMA antennas can be arranged in different configurations, where the maximum distance between antennas can vary from 150 metres to 16 kilometres, which will give ALMA a powerful variable “zoom”. It will be able to probe the Universe at millimetre and submillimetre wavelengths with unprecedented sensitivity and resolution, with a vision up to ten times sharper than the Hubble Space Telescope, and complementing images made with the VLT Interferometer. Light at these wavelengths comes from vast cold clouds in interstellar space, at temperatures only a few tens of degrees above absolute zero, and from some of the earliest and most distant galaxies in the Universe. Astronomers can use it to study the chemical and physical conditions in molecular clouds — the dense regions of gas and dust where new stars are being born. Often these regions of the Universe are dark and obscured in visible light, but they shine brightly in the millimetre and submillimetre part of the spectrum.

Gegenschein in a Fulldome view of Cerro Paranal
In the foreground, we can see the white Meteorological Tower of Paranal. The small dome contains a telescope dedicated to monitoring the atmospheric seeing conditions, known as a Differential Image Motion Monitor (DIMM.) In the sky at the upper left side of the this fish-eye (fulldome) picture, we can see the Gegenschein, that is a faint brightening of the night sky in the region of the antisolar point. like the zodiacal light, the gegenschein is sunlight scattered by interplanetary dust. Most of this dust is orbiting the Sun in about the ecliptic plane. It is distinguished from zodiacal light by its high angle of reflection of the incident sunlight on the dust particles. In the upper right side, is also visible the Large Magellanic Cloud (LMC) and above it, the Small Magellanic Cloud (SMC). Envolving the entire sky, we can see the presence of green airglow.

The light beams are combined in the VLTI using a complex system of mirrors in underground tunnels where the light paths must be kept equal to distances less than 1/1000 mm over a hundred metres. With this kind of precision the VLTI can reconstruct images with an angular resolution of milliarcseconds, equivalent to distinguishing the two headlights of a car at the distance of the Moon.

Milky Way Crossing the Sky of ALMA
Above the last antenna in the left center horizon, the bright object visible is not a star itself, but the great globular cluster Omega Centauri. Next to it, in the beginning of Milky Way arc, are spotted the bright stars of Alpha and Beta Centauri. Along his path we can enjoy the magnificent presence of our Galaxy full of gas and dust, star clusters and emission nebulae, as well as the orange star Antares from Scorpius constellation, and the dark streaks that are part of Rho Ophiuchi cloud complex, which connects this region to the main arm of Milky Way. Below right, we find planet Saturn and a faint white light called the Zodiacal Light, coming up as a backlight behind the antenna of ALMA (DV-21) with12 meters in diameter, is capturing the wavelengths from vast cold clouds in the interstellar space. This are the first tests to experiment the largest configuration that ALMA can support, with antennas spread over distances up to 16 km. The array thus simulates a giant, single telescope much larger than any that could actually be built. In fact, ALMA has a maximum resolution which is even better than that achieved, at visible wavelengths, by the Hubble Space Telescope.
The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical interferometer of radio telescopes in the Atacama desert of northern Chile. Since a high and dry site is crucial to millimeter wavelength operations, the array has been constructed on the Chajnantor plateau at 5,000 meters altitude, near Llano de Chajnantor Observatory and Atacama Pathfinder Experiment. Consisting of 66 12-meter (39 ft), and 7-meter (23 ft) diameter radio telescopes observing at millimeter and submillimeter wavelengths, ALMA is expected to provide insight on star birth during the early universe and detailed imaging of local star and planet formation. ALMA is a single telescope of revolutionary design, composed initially of 66 high-precision antennas, and operating at wavelengths of 0.32 to 3.6 mm. Its main 12-meter array has fifty antennas, 12 meters in diameter, acting together as a single telescope — an interferometer. An additional compact array of four 12-meter and twelve 7-metre antennas complements this. The 66 ALMA antennas can be arranged in different configurations, where the maximum distance between antennas can vary from 150 metres to 16 kilometres, which will give ALMA a powerful variable “zoom”. It will be able to probe the Universe at millimetre and submillimetre wavelengths with unprecedented sensitivity and resolution, with a vision up to ten times sharper than the Hubble Space Telescope, and complementing images made with the VLT Interferometer. Light at these wavelengths comes from vast cold clouds in interstellar space, at temperatures only a few tens of degrees above absolute zero, and from some of the earliest and most distant galaxies in the Universe. Astronomers can use it to study the chemical and physical conditions in molecular clouds — the dense regions of gas and dust where new stars are being born. Often these regions of the Universe are dark and obscured in visible light, but they shine brightly in the millimeter and submillimetre part of the spectrum.
ALMA is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA will study the building blocks of stars, planetary systems, galaxies and life itself. By providing scientists with detailed images of stars and planets being born in gas clouds near our Solar System, and detecting distant galaxies forming at the edge of the observable Universe, which we see as they were roughly ten billion years ago, it lets astronomers address some of the deepest questions of our cosmic origins.

Very Large Telescope Platform in the Twilight
Nautical twilight, above the Very Large Telescope platform. Near the horizon the bright moon is shining above the Antu telescope, the first one near the center. At his left, above the horizon are visible some of the Auxiliary Telescopes (ATs) of 1.8 m aperture. At the right side of Antu, the telescopes Kueyen, Melipal and Yepun, with mirrors of 8.2m diameter, are opening and preparing for a night of observations. This telescopes are generally used separately, but can be used together to achieve a very high angular resolution. Looking from outside, they are reflecting a silver color coming from the moon reflection on its metalic surface. In the ground, at the left side of the image, we can see part of the interferometer (VLTI) complex, where the movable Auxiliary Telescopes can be placed.
The Very Large Telescope (VLT) is a telescope operated by the ESO – European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. The 8.2m diameter Unit Telescopes can also be used individually. With one such telescope, images of celestial objects as faint as magnitude 30 can be obtained in a one-hour exposure. This corresponds to seeing objects that are four billion (four thousand million) times fainter than what can be seen with the unaided eye. The telescopes can work together, to form a giant ‘interferometer’, the ESO Very Large Telescope Interferometer, allowing astronomers to see details up to 25 times finer than with the individual telescopes.

Milky Way Arm Crossing Antu, Kueyen and Melipal Telescopes
Milky Way arm of gas and dust lying behind the Very Large Telesope Antu, Kueyen e Melipal, while it is capturing the light coming from space. At the right edge of the image, we can see the VLT Survey Telescope (VST), that is the latest telescope to be added to ESO’s Paranal Observatory in the Atacama Desert of northern Chile.
The Very Large Telescope (VLT) is a telescope operated by the ESO – European Southern Observatory on Cerro Paranal in the Atacama Desert of northern Chile. The VLT is the world’s most advanced optical instrument, consisting of four Unit Telescopes with main mirrors of 8.2m diameter, which are generally used separately but can be used together to achieve very high angular resolution. The four separate optical telescopes are known as Antu, Kueyen, Melipal and Yepun, which are all words for astronomical objects in the Mapuche language, with optical elements that can combine them into an astronomical interferometer (VLTI), which is used to resolve small objects. The interferometer is complemented by four movable Auxiliary Telescopes (ATs) of 1.8 m aperture. The 8.2m diameter Unit Telescopes can also be used individually.

Work in Progress in Very Large Telescope
In the upper left side of this fish-eye view, we can see the Gegenschein, that is a faint brightening of the night sky in the region of the antisolar point. In the center, the Yepun VLT Telescope is rotating with his astronomy work in progress, while the right side of the image shows the Large (LMC) and Small (SMC) Magellanic Clouds shining bright. A shy part of the Milky Way is also visible along with the right edge.

Stunning view of the Milky Way above Atacama Large Millimeter/submillimeter Array (ALMA)
In the background we can see the heart of our Galaxy full of gas and dust, star clusters and emission nebulae, as well as the orange star Antares from Scorpius constellation and the dark dust that conects this region to the main arm of Milky Way.

Magellanic Clouds, Zodiacal Light and Gegenschein on a VLT Panorama
In the left side of this – almost 360º- panoramic view, we can see Canopus star and the Large (LMC) and Small (SMC) Magellanic Clouds. Above the horizon, in the beginning of Milky Way arc, are yet visible the bright stars Alpha and Beta Centauri. At the center, lie down the galactic arm with the Zodiacal Light as a background of Antu telescope. Next to the last telescope is clearly visible the elongated diffuse light coming from Andromeda galaxy. In the upper part of the image and opposite direction of Magellanic Clouds, is shining a Gegenschein, that is a faint brightening of the night sky in the region of the antisolar point. Like the zodiacal light, the Gegenschein is sunlight scattered by interplanetary dust. Most of this dust is orbiting the Sun in about the ecliptic plane. It is distinguished from zodiacal light by its high angle of reflection of the incident sunlight on the dust particles. Below right and near the horizon, the Pleiades (M45) star cluster is visible next the tower silhouette.
