Reddish Airglow in a Fulldome view of Very Large Telescope
In this fish-eye fulldome picture, we can see a partial cloudy sky, that can promote sometimes the appearance of a beautiful show. Specially, if we have a night of Moonlight that can illuminate and show a strange game of ghostly shapes in the clouds. In the background a starry sky with a shy Milky Way is showing a strong presence of reddish airglow in the opposite direction of the Very Large Telescope.
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.

Cerro Armazones, the home for the European Extremely Large Telescope (E-ELT)
Above the horizon we can see Cerro Armazones mountain iluminated by the sunset redish color that is reflected in the land and high clouds . With an altitude of 3060 metres in the central part of Chiles Atacama Desert, some 130 kilometres south of the town of Antofagasta and about 20 kilometres from Cerro Paranal, home of ESOs Very Large Telescope. Cerro Armazone will be the baseline site for the planned 39-metre-class European Extremely Large Telescope (E-ELT), with a planned construction period of about a decade. The telescope’s “eye” will be almost half the length of a soccer pitch in diameter and will gather 15 times more light than the largest optical telescopes operating today. The telescope has an innovative five-mirror design that includes advanced adaptive optics to correct for the turbulent atmosphere, giving exceptional image quality. The main mirror will be made up from almost 800 hexagonal segments.

Belt of Venus above the DIMM tower in 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 background is strongly visible the Earth’s shadow, the shadow that the Earth itself casts on its atmosphere. This shadow is visible in the opposite half of the sky to the sunset or sunrise, and is seen right above the horizon as a dark blue band. Immediately above, a pink band that is visible above the dark blue of the Earth’s shadow is called “Belt of Venus”, and is caused by backscattering of refracted sunlight due to fine dust particles high in the atmosphere.

Twilight and Sun Pillar in Cerro Paranal
After the sunset, in the beginning of twilight, a partial cloudy sky can promote an impressive combination of beautiful colors. Sometimes, we can see a phenomenon called Sun Pillar. A sun pillar is a vertical shaft of light extending upward from the sun. This great moment was captured in Cerro Paranal, where stands the VLT Telescope.

VLT Residencia with Orion, Sirus, Canopus and Magellanic Clouds
In the left side of the sky we can see the Orion constellation with the orientation inverted for being seen from the Southern Hemisphere, close to the right, we can find the brightest star of the entire celestial sphere and Northen Hemisphere, Sirius. Moving further up, in the center of the image, is located the Canopus star, the brightest star of Southern Hemisphere. Next to it, is well spoted the Large and Small Magellanic Clouds, a duo of irregular dwarf galaxies, which are members of the Local Group and are orbiting the Milky Way galaxy. In the ground, we can see the white dome of Residencia where astronomers from ESO that are working daily on VLT complex are hosted. In the background we also can see a tone of green and reddish faint light, coming from the airglow phenomenon.

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.

Enjoying Venus corona above the Giant´s Causeway – Northen Ireland
In the image we can see a Skygazer enjoying the planet venus with a visible corona phenomenon between the Giant’s Causeway, near Bushmills, in northeast coast of Northen Ireland. Is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption, 60 million years ago. It was declared a World Heritage Site byUNESCO in 1986. Near the top edge of the image we can see the Pleiades star cluster.
Corona, is produced by the diffraction of light from either the Sun, the Moon or some bright planets by individual small water droplets and sometimes tiny ice crystals of a cloud.

Airglow and Milky Way from Pico do Arieiro
The strong airglow can be seen above the horizon in this panoramic view captured in the top of Madeira island, in Pico do Arieiro, at about 1810 meters high. Above the green pale light shines the Milky Way between the passing clouds. At the right top of the mountain, above the white/yellow dome – a military radar – shines the well known winter constellation of Orion and a further high to the left, stands the open cluster Pleiades (M45).

In this wide view we can see a blueish white aureole around planet Jupiter, seems to the larger aureoles that occur around the Sun and Moon due to the presence of ice crystals in the atmosphere. Beside the intentional overexposed disc of planet Jupiter, and also involved inside the aureole circular shape, are also visible the well known four Galilean moons: Ganymede, Io, Callisto and Europa – observed for the first time 400 years ago by Galileu Galilei – only part of the 67 confirmed moons that are orbiting the biggest planet of our solar system. In the moment of the capture, Jupiter was about 22º above the horizon in the Gemini constellation, with an apparent diameter of +0º 00´38.8″ at a distance of 5.075644 AU with a magnitude of -1.81. Below is the annotated version with the identification of each Jupiter moons.

Clouds and Fog in Caldera de Taburiente
Captured in a height of 2,200 meters from the sea level we can see the clouds and Fog near the border of Caldera de Taburiente – a very large volcanic crater with about 10 km across. Above the horizon the sun sets behind the silhouette mountains of Roque de Los Muchachos, where stands a huge complex with the some of the largest telescopes in the world. The picture was taken in Pico de La Cruz, La Palma, Canary Island.

A dreaming view from Heavens
A panoramic view from Roque de Los Muchachos on the Canary island of La Palma, where stands a huge complex with 15 telescopes, some of the largest telescopes in the world – many of them visible in the background – from 19 nations, that are using the best night sky in Europe to explore the cosmos.
In the foreground – both edges of the image – stands the MAGIC telescope I and II (Major Atmospheric Gamma-ray Imaging Cherenkov Telescopes). MAGIC-II is located at a distance of 85 m from the first MAGIC telescope (at right). The stereo operation of both telescopes has increased the sensitivity of the observatory by a factor of ~3. MAGIC-II (at left) is a copy of the original MAGIC-I but it has a more homogeneous camera with more pixels, and a refurbished readout. In 2012, in a major upgrading operation mostly concerning MAGIC-I, the two telescopes were made technically identical. MAGIC is not only huge (it was the largest telescope mirror in the world, with 17 meters in diameter, before the construction of H.E.S.S.) but also pioneers a number of technical developments that had never been applied to Cherenkov telescopes before. The mirror is extremely light and can be moved to any position in the sky in less than thirty seconds. It is made up of 270 individual mirror panels that can be independently focussed using an active mirror control system equipped with lasers.
Between the both giant Cherenkov Telescopes, stands the mountain top of the Roque de los Muchachos, where is placed from right to left, telescopes like Gran Telescopio Canarias (GTC), with a 10,4 meters primary mirror reflecting telescope (first silhouette), Telescopio Nazionale Galileo (TNG), that is a 3.6m alt-azimuth telescope with a Ritchey-Chretien optical configuration, Nordic Optical Telescope (NOT) a modern 2.6-m optical/IR telescope, Dutch Open Telescope (DOT) an innovative optical telescope with a primary mirror of 45 cm diameter, for high-resolution imaging of the solar atmosphere, Swedish 1-m Solar Telescope (SST) is the largest solar telescope in Europe and number one in the world when it comes to high spatial resolution, and finally the great William Herschel Telescope (WHT), the largest optical telescope of its kind in Europe, with a primary mirror of 4.2 meters in diameter, is one of the most scientifically productive telescopes in the world.
Between the William Herschel Telescope and the MAGIC (at left) the sky shows the Pleiades star cluster M45, and a bit above, semi hidden behind the antenna we can find the deep sky object California nebula NGC1499. From left to right edge, the sky shows the presence of a strong green airglow of oxygen atoms (90-100 km high), and shining in the center image as an orange bands – normally from oxygen atoms at 150-300km high where the atmosphere is so sparse and collisions so infrequent that the atoms have time to radiate ‘forbidden’ light. Finally, against the MAGIC I (in the right corner of the picture), lies our own Galaxy, the Milky Way.

Observatories, Earth Shadow and Belt of Venus
In this picture captured few minutes after the sunset from Roque de Los Muchachos, in La Palma Canary Island, we can see the Earth shadow, a dark blue band that rises upwards from the horizon. The band is the shadow of the Earth on the atmosphere. Immediately above, where the evening air is still lit, glows a pink band called the anti-twilight arch, or “Belt of Venus”. On Earth, stands part of a huge complex with 15 telescopes, some of the largest telescopes in the world. From left to right, the grey dome open is the shelter for the Nordic Optical Telescope (NOT) a modern 2.6-m optical/IR telescope, next, the small white house is the home for Automatic Transit Circle (ATC), an old meridian circle built by Grubb-Parsons in 1950 but completely refurbished and automatized in the 70’s of the past century by the Copenhagen University Observatory (CUO). It main task is to observe evenly bodies at their transit across the meridian. At his right, the big white dome belongs to the great William Herschel Telescope (WHT), the largest optical telescope of its kind in Europe, with a primary mirror of 4.2 meters in diameter, is one of the most scientifically productive telescopes in the world. Next, the small shape in the background near the first white tower is from Liverpool Telescope, a 2 meter diameter optical astronomical telescope, constructed especially for robotic use. The telescope is especially to study variable astronomical phenomena. Now, the first white Tower is from Dutch Open Telescope (DOT) an innovative optical telescope with a primary mirror of 45 cm diameter, for high-resolution imaging of the solar atmosphere. Next far, the silver small dome is from Mercator Telescope, a 1.2 m quasi-robotic telescope which scientific niche is focussed on monitoring variable celestial phenomena with a large range in typical time-scales (pulsating stars, gravitational lenses, Gamma Ray Bursts, active Galactic Nuclei), immediately adjacent to the next tower (just in the picture) we can see the Swedish 1-m Solar Telescope (SST), the largest solar telescope in Europe and number one in the world when it comes to high spatial resolution. The last white domes belongs to Isaac Newton Telescope (INT) with a 2.54-meter primary mirror and the Jacobus Kapteyn Telescope (JKT) with a parabolic primary mirror of 1.0 m diameter.

Zodiacal Light, Milky Way and William Herschel Telescope
In this mosaic of 25 images, we can see the rocky silhouette between Los Andenes and Roque de Los Muchachos, where is the home to one of the most extensive fleets of telescopes to be found anywhere in the world, and where 15 telescopes from 19 nations are using the best night sky in Europe to explore the cosmos. The William Herschel Telescope (WHT) is one of them, with a primary mirror of diameter 4.2 meters, the telescope can be seen below right in the picture, with is dome opened, seems to pointing to the triangle formed in the middle of the picture by the smooth band of Zodiacal light (at left) which is crossing the Milky Way smooth region (at right), below the Orion constellation. These smooth bands are also important to let us find objects, like M44 above the rocks, and following the zodical light we find the planet Jupiter, the brightest star in the image. In the middle of Milky Way band, we can find the Rosette nebula. The Moon is shining in Cancer constellation, behind the rocks and below right to the star cluster M44 (NGC2632), so creating a blueish glow – more strong and evident – in the left half part of the picture.

Air Glow, Milky Way and the Great Lake Alqueva
This serene view, captured on the great lake Alqueva, near the “Ermida de São Pedro” in Mourão, one of the regions belonging to the Dark Sky Alqueva Reserve, we find several scientifically interesting things. In the center of the picture we can see the natural colors of the most central region of the Milky Way, located near the Scorpio and Sagittarius constellation, where is it possible to recognize many deep sky objects like the Lagoon Nebula (M8) and the Trifid Nebula (M20). In the image was also possible to register a strong presence of Air Glow (Atmospheric Chemiluminescence) , the further thing I have seen similar to an Aurora, which crossed ahead the region of scorpion, with yellow light, by emissions from sodium atoms in a layer at 92 km. Above it, we could see the green light from oxygen atoms in a layer 90-100 km high. This emission layer is clearly visible from earth orbit.
Reflected in the peaceful lake and due to the polarization effect of water, we could clearly see the entire constellation of Scorpius with the real color of each star naturally saturated, due to this polarization and blurred effect, caused by the slowly movement of water during the long exposure. The orange color of the Red Supergiant Antares could be easily distinguished from the blue color of the Subgiant star, Shaula, in the end of tail.

This serene view, captured on the great lake Alqueva, near the “Ermida de São Pedro” in Mourão, one of the regions belonging to the Dark Sky Alqueva Reserve, we find several scientifically interesting things. In the left top corner of the image, we could find the Cassiopeia constellation and below the double cluster NGC 884 and 869. Almost in the center image, is clearly visible the great Andromeda Galaxy M31, in Andromeda constellation, the neighbor of Pegasus. Above the Alqueva Lake, is visible the strong presence of Air Glow (Atmospheric Chemiluminescence) , the further thing I have seen similar to an Aurora, with yellow light, by emissions from sodium atoms in a layer at 92 km.

Big Dipper, Air Glow and Gravity Waves in Mourão Dark Sky
In this picture captured in the great lake Alqueva, near the “Ermida de São Pedro” in Mourão, one of the regions belonging to the Dark Sky Alqueva Reserve, we cloud see the strong presence of Air Glow (Atmospheric Chemiluminescence) involving the Big Dipper constellation (Ursa Major) with the green light from oxygen atoms in a layer 90-100 km high. This emission layer is clearly visible from earth orbit. In the image, is also visible the gravity waves effect. “These waves (internal gravity or buoyancy waves) abound in the stable density layering of the upper atmosphere. Their effects are visibly manifest in the curls of the stratosphere’s nacreous clouds, in the moving skein-like and billow patterns of the mesosphere’s noctilucent clouds and in the slowly shifting bands of the thermosphere’s airglow, as we could see in this picture and in the annotated version of this same image.

Alqueva Lake, a natural “Star Seismograph”
This startrail captured in a region of the sky facing south and where is present part of the Milky Way, thus causing a nuance of shades that blend background with well-marked trails of stars in the sky. These tracks, reflected in the lake as if they were “written” by a needle of a seismograph, also due to the effect of polarization, a characteristic effect of the water, allows accentuating the true color of the stars … well reported at the bottom of the image. The hottest stars are blue. The most blue pronounced reflection is caused by the Shaula star, which lies at the tip tail of the Scorpion, as we were able to confirm this “with the natural seismograph” better known as “Great Lake Alqueva” and part of Dark Sky Reserve.

Gas and Dust Up to the Zenith
A view of the Milky Way in a vertical dizzying mosaic up to the Zenith. As a photographer and book author, I’d say: maybe an image in a “tab book format” where we can still see the yellowish effect of ariglow and the area of cloudiness (gas and dust) that make up the Milky Way, with several emission nebulae visible in the image (in violet tone). The picture was taken in a region of the Hermitage of San Pedro, in Mourão. The brightest stars have left his trademark on the calm water, which mirrored again, the beauty of the universe!

Crepuscular Rays in Tomina
Image captured near Convento da Tomina region, a area inside the great Contenda homestead, near Moura and Barrancos, Portugal. In the sky we could see the dramatic effect of the phenomenon known as “Crepuscular rays, in atmospheric optics, are rays of sunlight that appear to radiate from the point in the sky where the sun is located. These rays, which stream through gaps in clouds (particularly stratocumulus) or between other objects, are columns of sunlit air separated by darker cloud-shadowed regions. Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight, and their apparent convergence is a perspective effect (similar, for example, to the way that parallel railway lines seem to converge at a point in the distance).”
“The name comes from their frequent occurrences during crepuscular hours (those around dawn and dusk), when the contrasts between light and dark are the most obvious. Crepuscular comes from the Latin word “crepusculum”, meaning twilight.”

The Blue Sirius
In this picture captured from the walls of Monsaraz Castle, we can see the entire Canis Major constellation, the star cluster M41, and the brightest star in the celestial sphere, with -1.46 mag. In this image Sirius is shown with unusual strong sparkles, not only produced by a photo star filter attached in the front lens of the camera, but also due to the strong dew which increase the diffusion and saturation effect, showing so, the true blue color of this star, for being at a hot temperature of 25,200K.

The Moon was not alone
This image was captured in the land of Juromenha, near Alandroal, one of the regions covered by the Alqueva´s Dark Sky Reserve (www.alquevadarksky.com), distinguished as the Worlds First Star Light Tourism Destination.However, during the two nights that I was shooting, I had the great presence of the moon to light up the landscape, creating many different blue sky tones and showing less stars than we usually see, with naked eye. The moon, let me capture the beauty of the place with incredible romantic views in a scenery full of quiet, peace and plenitude. Lakes, horses and millenar olive trees, is just an example of what we could find there…

Lagoa das Sete Cidades at Night – Azores
Lagoa das Sete Cidade (English: Lake of the Seven Cities) is a twin-lake situated in the crater of a massive crater on the Portuguese archipelago of the Azores. It consists of two ecologically-different small-lakes connected by a narrow passage (and crossed by a bridge), located inside a dormant volcano on the western third of the island of São Miguel. The Lagoa das Sete Cidades part of a natural landscape of communitarian interest: it is the largest body of water in the region and one of the most important freshwater resources in the archipelago.

This place have a peculiar weather and we could see in this image taken at a deep night with a long exposure, a strange cloud formation that is around the volcano crater as well as all the light pollution reflected in the clouds, from the small village that exists in the center of the crater. The air planes normally avoid to fly above it.
