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.

Atacama Desert View with Cerro Armazones
From left to right and above the horizon we can see in this panoramic view of Atacama desert, the Cerro Armazones mountain, illuminated by the sunset reddish color that is reflected in the land and high clouds, coming from the right edge of the image in the opposite direction, where it is located the Pacific Ocean. With an altitude of 3060 meters in the central part of Chiles Atacama Desert, some 130 kilometers south of the town of Antofagasta and about 20 kilometers from Cerro Paranal, home of ESOs Very Large Telescope. Cerro Armazones will be the baseline site for the planned 39-meter-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.

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.
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.

Profile of Antenna DV-21 from ALMA in the Twilight
After the sunset starts the nautical twilight and the sky assumes a beautiful pallete of blueish and orange colors, giving space to appearing the first stars of the some constelalltions. 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.

Stunning view of the Milky Way above ALMA along with the Moonset
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 connects this region to the main arm of Milky Way. Below at right, a faint white light called the Zodiacal Light is very well visible, 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. Above the horizon we also can see an orange glow coming from the moonset. 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.

Twilight Above the interferometer VLTI
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, is the telescope Kueyen, with a mirror of 8.2m diameter. Both, 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.

Silhouette of Noudar Church in a Starry Trail Background
Included in the great Alqueva Dark Sky Reserve – first site in the world to receive the “Starlight Tourism Destination” certification – Noudar Natural Park is located in a farm estate called Herdade da Coitadinha spreads across 1000 hectare, ‘over-the-hills’ between the winding rivers Ardila and Múrtega and lodged among hills and summits near the town of Barrancos (Alentejo, Portugal) and in the border with Spain. The road from the Park’s entrance to the Noudar Castle goes through an extensive holm oak grove (‘montado’) area, ending with a majestic view over the water lines. In Noudar, life presents itself in a state of wilderness and absolute purity.
The Castle of Noudar and the church of Nossa Senhora do Desterro is located between the Múrtega and the Ardila rivers which flow towards the West. Its construction was finished in 1307, during the reign of Don Dinis. The place was chosen because of its natural defenses, easy access and the closeness of a water spring of excellent quality – Fonte da Figueira, located roughly 250 meters to the East of the castle, under the hilltop known as Forca (“the Gallows”). Good and plentiful farming land and cattle grazing fields can also be found near the castle. This medieval fortress was very important for border defense against the kingdom of Castile during the early 14th Century.

Colorful Twilight in Roque de Los Muchachos
In this colorful twilight view captured after the sunset from the top of El Roque de Los Muchachos, home to one of the most extensive fleets of telescopes to be found anywhere in the world, we can see a startrail with an amazing view of planet Venus (the brightest trail at left), reflected in the “ocean of clouds” below the land. On earth, the bright trail was left by the lights of a car that was moving inside the observatory area, where is visible from left to right, the Telescopio Nazionale Galileo. TNG is a 3.6m alt-azimuth telescope with a Ritchey-Chretien optical configuration and a flat tertiary mirror feeding two opposite Nasmyth foci and represents the largest Italian optical/infrared telescope. On the right edge of the picture stands the Gran Telescope Canarias (GTC) with a 10,4 meters primary mirror reflecting telescope was designed to incorporate the most up-to-date technology and it is one of the most advanced telescopes in the world, actually, the largest one until now in the optical-infrared system

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.

A Road to Big Dipper
The Big Dipper (Ursa Major) lies in the “end” of the road to Roque de Los Muchachos, where a stargazer is enjoying the great sky of La Palma. The excellent quality of the sky for astronomy in the Canaries is determined and protected by Law. As a result, the observatories of the Instituto de Astrofísica de Canarias (IAC) are an “astronomy reserve” which has been available to the international community since 1979. I´ve used a diffuse filter in the camera lens, to increase and highlight the main stars of Ursa Major.

Venus and Saturn in Libra from Los Andenes
The Nautical Twilight seen from Los Andenes, near Roque de Los Muchahos, in La Palma, where we could see the strong light of planet Venus (the strongest light in the picture) inside the stellar asterism with a trapezium shape, that forms the Libra constellation. In the same imaginary line which conects Venus to the Zubenelgenubi star, we can find the planet Saturn, the third brightest object in the picture (at the right side of the image) almost with the same brightness of Antares, from Scorpius constellation, visible in the top of the picture as an orange star. Below the horizon, we found an ocean of clouds, located inside the Caldera. The rocky silhouette is part of Roque de Los Muchachos, where stands a huge complex with the some of the largest telescopes in the world.

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.

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.”

Comet PanSTARRS over Almada
After a few days of rain and clouds in the horizon, I can finally photograph the comet PanSTARRS in the portuguese sky. Actually, I was arrived from a weekend photo trip and was exausted, but the sky was totally clear, so, I found some “extra forces” to delay my sleep, and I´ve tried to find this view from my home window.
Near and below the comet there was two stars with a magnitude of +6.3. (HIP2734 / HIP 2832).The image was captured in the city of Almada, near Lisbon, Portugal.
