Cerro Armazones - Cerro Armazones in the Atacama desert. This 3060-metre mountain in Chile will host the giant telescope E - ELT (European Extremely Large Telescope). The construction of this 42-metre telescope is expected to start at the end of 2010 and will be inaugurated around 2018. Its main mirror will consist of 906 hexagonal mirrors assembled together, and its total surface will be equal to that of a football field. View of Cerro Armazones in the Chilean desert, near Eso's Paranal Observatory, site of the Very Large Telescope (VLT). Cerro Armazones was chosen as the site for the planned European Extremely Large Telescope (E - ELT), which, with its 42 - metre diameter mirror, will be the world's biggest eye on the sky

Telescope E - ELT - Artist's view - European Extremely Large Telescope - Artwork - Artist's view of the E - ELT (European Extremely Large Telescope), a telescope project measuring 40 metres in diameter. Its main mirror will consist of 906 hexagonal mirrors assembled together, and its total surface will be equal to that of a football field. A new architectural concept drawing of Eso's planned European Extremely Large Telescope (E - ELT) shows the telescope at work, with its dome open and its record - setting 40 - metre - class primary mirror pointed to the sky. In this illustration, clouds float over the valley overlooked by the E - Elt's summit. The comparatively tiny pickup truck parked at the base of the E - ELT helps to give a sense of the scale of this massive telescope. The E - ELT dome will be similar in size to a football stadium, with a diameter at its base of over 100 m and a height of over 80 m.

NGC 6814 has an extremely bright nucleus, a telltale sign that the galaxy is a Seyfert galaxy. These galaxies have very active centres that can emit strong bursts of radiation. The luminous heart of NGC 6814 is a highly variable source of X-ray radiation, causing scientists to suspect that it hosts a supermassive black hole with a mass about 18 million times that of the Sun. As NGC 6814 is a very active galaxy, many regions of ionised gas are studded along its spiral arms. In these large clouds of gas, a burst of star formation has recently taken place, forging the brilliant blue stars that are visible scattered throughout the galaxy

The measurements obtained by the Hubble telescope showed that this star, Pismis 24 - 1, was actually a double star and that its mass was actually only about 100 solar masses. The small open star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 in Scorpius, about 8,000 light - years away from Earth. Some of the stars in this cluster are extremely massive and emit intense ultraviolet radiation. The brightest object in the picture is designated Pismis 24 - 1. It was once thought to weigh as much as 200 to 300 solar masses. This would not only have m

Nebula NGC 604 in the galaxy M33 - NGC 604 star forming nebula - NGC 604, is a very large star-forming region located in the galaxy M33 of the Triangle. This image is a composite of X-ray images (blue) obtained by the Chandra Space Telescope and visible (green and red) by the Hubble Space Telescope. The study of very hot gas observed in X-ray allows us to better understand the star formation activity within this nebula. NGC 604, is one of the largest known seething cauldrons of star birth in a nearby galaxy. NGC 604 is similar to familiar star - birth regions in our Milky Way galaxy, such as the Orion Nebula, but it is vastly larger in extent and contains many more recently formed stars. This monstrous star - birth region contains more than 200 brilliant blue stars within a cloud of glowing gases some 1,300 light - years across, nearly 100 times the size of the Orion Nebula. The bright stars in NGC 604 are extremely young having formed a mere 3 million years ago. The most massive stars

Planet Ross 128 b, with its red dwarf parent star in the background. This planet, which lies only 11 light-years from Earth, was found by a team using Eso's unique planet-hunting HARPS instrument. The new world is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life. Ross 128 b will be a prime target for Eso's Extremely Large Telescope, which will be able to search for biomarkers in the planet's atmosphere

Nebula IC 2220 in the Carene - The IC 2220, nebula, deep image - This nebula is illuminated by a large red star, the star HD 65670. Image obtained by Siding Spring's 3.9m telescope. Many stars lose a substantial part of their mass as they age. The more massive the star, the greater the fraction of their substance is lost. Much material is ejected by intense stellar winds driven from the surface of extremely hot stars and the mass loss is often only detectable in the stellar spectrum. In cooler stars temperatures may be low enough for elements or simple compounds to form solid grains in the star's outer atmosphere. This is seen as dust, and sometimes there is enough to reflect the light of the star within. As is often the case with stellar outflows, the IC 2220 reflection nebula is bipolar, hinting at conditions near the surface of the central star

This remarkable spiral galaxy seen almost edge - on, and the spiral structure is chaotic and difficult to discern. In part this is because the galaxy is itself extremely dusty, and it is seen through dust in the Milky Way.

The dust in NGC 4945 absorbs most of the visible light, especially the blue light from the numerous bright stars known present within the galaxy. This energy is re - radiated at infrared wavelengths, which penetrate dust more readily, which is why the galaxy is found to be unusually bright in the infrared

Light echo of supernova 1987A - July 1989 - The light echo of supernova 1987A - July 1989 - Image obtained with Siding Spring's 3.9m telescope. Supernova 1987A appeared in the constellation Doradus on February 23, 1987. When supernova 1987A was seen to explode in the Large Magellanic Cloud, the Milky Way's nearest companion galaxy, the brilliant flash of light from the self - destructing star had taken about 170,000 years to arrive. Some light was deflected by two sheets of dust near the supernova, and is seen after the star has faded away because it covers a longer path to reach us. The dust responsible for the rings seen here lies in two distinct sheets, about 470 and 1300 light years from the supernova. The colour picture, made by subtracting images on plates taken before and after the supernova, is an accurate reproduction of the colour of the extremely faint light echo, which in turn reflects the yellow colour of the supernova when it was at its brightest, in May 1987.

Barree spiral galaxy NGC 1097 - NGC 1097, a barred spiral galaxy and elliptical companion - Located at a distance of about 45 million years - light in the constellation of the Furnneau, NGC 1097 is subject to intense star formation and is an active nucleus galaxy with a supermassive black hole in its heart. At the top right of the image, a special elliptical satellite galaxy, NGC 1097A, probably interacted with NGC 1097 in the past. Image obtained by Siding Spring's 3.9m telescope. NGC 1097 is a fine, barred spiral galaxy seen from a distance of about 50 million light years. The galaxy is unusual in several respects. It is a fairly strong radio source and is also bright at far infrared wavelenghts, indicating the presence of warm dust. The galaxy is also interacting woth a small elliptical galaxy, seen in the upper right (NW) corner of the picture.

Nebula of the Lagoon (M8) in Sagittarius - The Hourglass Nebula in M8, NGC 6523 - View of the Nebula of the Lagoon (M8/NGC 6523). Located in Sagittarius, at a distance of 5800 years - light, it is visible to the naked eye in good conditions. It is a star-forming region illuminated by several large O-type stars that belong to the open cluster NGC 6530 visible on the left of the image. The brightest part of the nebula is called the hourglass nebula whose gases are excited mainly by two massive supergeant stars Herschel 36 and 9 Sagittarii. At the heart of the Lagoon Nebula in Sagittarius lies the diminutive Hourglass Nebula. This extremely bright object is associated with the blue star alongside it, named Herschel 36 after its discoverer. Herschel described M8 as 'A noble nebula' and 'a fine and complicated nebula', but he was clearly intrigued by the Hourglass which he compared to the nucleus of the Andromeda nebula, M31 as 'decidedly not stellar'. The tiny bright nebula that captures H

Nebuleuse N44 in the Great Magellan Cloud - This photo shows the southern part of the spectacular N44 region in the Large Magellanic Cloud. The green colour indicates areas that are particularly hot. The field measures 27.5 x 26.5 arcmin2., North is up and East is left. The two best known satellite galaxies of the Milky Way, the Magellanic Clouds, are located in the southern sky at a distance of about 170,000 light - years. They host many giant nebular complexes with very hot and luminous stars whose intense ultraviolet radiation causes the surrounding interstellar gas to glow. The intricate and colourful nebulae are produced by ionised gas that shines as electrons and positively charged atomic nuclei recombine, emitting a cascade of photons at well defined wavelengths. Such nebulae are called “” H II regions””, signifying ionised hydrogen, i.e. hydrogen atoms that have lost one electron (protons). Their spectra are characterized by emission lines whose relative intensities carry usefu

Supernova Sn 2004dj in the galaxy NGC 2403 - The explosion of a massive star blazes with the light of 200 million Suns in this NASA Hubble Space Telescope image. The supernova is so bright in this image that it easily could be mistaken for a foreground star in our Milky Way Galaxy. And yet, this supernova, called SN 2004dj, resides far beyond our galaxy. Its home is in the outskirts of NGC 2403, a galaxy located 11 million light - years from Earth. Although the supernova is far from Earth, it is the closest stellar explosion discovered in more than a decade. The star that became SN 2004dj may have been about 15 times as massive as the Sun, and only about 14 million years old. (Massive stars live much shorter lives than the Sun; they have more fuel to “” burn”” through nuclear fusion, but they use it up at a disproportionately faster rate.) The large number of massive stars in NGC 2403 leads to a high supernova rate. Two other supernovae have been seen in this galaxy during the past hal

Planetary nebula M57 (NGC 6720) in Lyra - M57 (NGC 6720) planetary nebula in Lyra - The planetary nebula of Lyra (M57) is located about 2000 years - light from Earth. With a magnitude of 9.0, this nebula is easily observed with a small telescope. A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its matter. Composite image obtained by different telescopes. The Ring Nebula, M57, is the most famous example of a planetary nebula. Located about 2,000 light years away, it has an apparent diameter of 1 arc minute and a real diameter of about one light year. At magnitude 9.0 its high surface brightness makes it an easy object, even from the city and even with small telescopes. Planetary nebula are shells of gas shed by stars late in their life cycles after using up all of their nuclear fuel. The star then ejects a significant portion of its mass in a gaseous shell, which is illuminated by its extremely
