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.

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.

Twilight With a New Large Configuration of Antennas in ALMA
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.

Testing ALMA Band Receiver in Laboratory
This picture shows an electronic engineer while is photographing the components in one of the Band receivers cartridges built for the Atacama Large Millimeter/submillimeter Array (ALMA), one of the most sensitive and expensive parts of the Antennas. Extremely weak signals from space are collected by the ALMA antennas and focussed onto the receivers, which transform the faint radiation into an electrical signal. Before its construction is even completed, the new ALMA (Atacama Large Millimeter/submillimeter Array) telescope has embarked on an upgrade that will help astronomers investigate the earliest galaxies and search for water in other planetary systems, designing and building of an additional set of receivers with state-of-the-art performance, which will enable the telescope to access a portion of the spectrum of light that it cannot currently study. ALMA observes the Universe in radio waves: light which is invisible to our eyes. The weak glow coming from space is collected by the ALMA antennas and focused onto the receivers that transform the feeble radiation into an electrical signal. ALMA has 10 receiver bands to cover a wide range of observing frequency. For more effective reception of different bands of frequency, dedicated receivers have been developed for each band. The new receivers will be able to detect electromagnetic radiation with wavelengths between about 1.4 and 1.8 millimeters, one of the ranges of the spectrum to which Earth’s atmosphere is partially transparent, which allows the light to reach the ALMA antennas. These wavelengths correspond to radio frequencies between 163 and 211 Gigahertz. ALMA has reached a major milestone by extending its vision fully into the realm of the submillimetre, the wavelengths of cosmic light that hold intriguing information about the cold, dark, and distant Universe.
