Barree spiral galaxy NGC 6872 in interaction with IC 4970 in the Peacock - Barred spiral interacting galaxy NGC 6872 in Pavo - The barree spiral galaxy NGC 6872 and lenticular IC 4970 are located about 300 million years away - light from Earth. NGC 6872 extends over nearly 750,000 years - light. Image obtained by the ANTU telescope of the VLT on March 29, 1999. View of the spectacular barred spiral galaxy NGC 6872 obtained with FORS1 at ANTU telescope (VLT) in the morning of March 29, 1999. It is of type SBB and is accompanied by a smaller, interacting galaxy, IC 4970 of type S0 (just above the centre). The bright object to the lower right of the galaxies is a star in the Milky Way whose image has been strongly overexposed and exhibits multiple optical reflections in the telescope and instrument. There are also many other, fainter and more distant galaxies of many different forms in the field. The upper left spiral arm of NGC 6872 is significantly disturbed and is populated by a pletho

Artist view of the planetary system around Gliese 581 - Planetary system around the red dwarf Gliese 581 - Artist view of the planetary system around the star Gliese 581. In the foreground, the exoplanet Gliese 581st. In the background, Gliese 581d (blueberry), in the center Gliese 581c and near the star, Gliese 581b. Gliese 581e (foreground) is only about twice the mass of our Earth. The Gliese 581 planetary system now has four known planets, with masses of about 1.9 (planet e, left in the foreground), 16 (planet b, nearest to the star), 5 (planet c, centre), and 7 Earth - masses (planet d, with the bluish colour). The planet furthest out, Gliese 581d, orbits its host star in 66.8 days, while Gliese 581 e completes its orbit in 3.15 days

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 42 metres in diameter. Construction of this European project could start in 2010, with a planned inauguration around 2017. Its main mirror will consist of 906 hexagonal mirrors assembled together, and its total surface will be equal to that of a football field. With a 42 - m diameter primary mirror, the present baseline, its total rotating mass is 5500 tons. The two platforms on each side of the structure hold large instruments. The telescope features a novel, innovative design, based on 5 mirrors. The primary 42 - m mirror is composed of 906 segments, each 1.45 m wide, while the secondary mirror is as large as 6 m in diameter. A tertiary mirror, 4.2 m in diameter, relays the light to the adaptive optics system, composed of two mirrors: a 2.5 - m mirror supported by 5000 or more actuators so as to be able to

Proxima du Centaur is located at a distance of 4.22 light years from the Sun but is invisible to the naked eye. Alpha Centauri A and B are a little further away, 4.36 light years from the Sun. These two stars are relatively similar to the Sun. Although Proxima of Centauri is distant from the Alpha couple of Centauri, its movement seems to link it to this system and is sometimes called Alpha Centauri C - This image of the sky around the bright star Alpha Centauri AB also shows the much fainter red dwarf star, Proxima Centauri, the closest star to the Solar System. The picture was created from pictures forming part of the Digitized Sky Survey 2. The blue halo around Alpha Centauri AB is an artifact of the photographic process, the star is really pale yellow in colour like the Sun. Proxima Centauri appears as a faint red star towards the lower-right of the picture

This artist's impression shows the exotic double object that consists of a tiny, but very heavy neutron star that spins 25 times each second, orbited every two and a half hours by a white dwarf star. The neutron star is a pulsar named PSR J0348+0432 that is giving off radio waves that can be picked up on Earth by radio telescopes. Although this unusual pair is very interesting in its own right, it is also a unique laboratory for testing the limits of physical theories. This system is radiating gravitational radiation, ripples in spacetime. Although these waves (shown as the grid in this picture) cannot be yet detected directly by astronomers on Earth they can be sensed indirectly by measuring the change in the orbit of

Detail of the horse's head nebula by the VLT - Horsehead Nebula, which is situated in the Orion molecular cloud complex. Its official name is Barnard 33 and it is a dust protrusion in the southern region of the dense dust cloud Lynds 1630, on the edge of the HII region IC 434. The distance to the region is about 1400 light - years (430 pc). This beautiful colour image was produced from three images obtained with the multi - mode FORS2 instrument at the second VLT Unit Telescope (KUEYEN) on February 1, 2000. Three predominant colours are seen in the image: red from the hydrogen (H - alpha) emission from the HII region; brown for the foreground obscuring dust; and blue - green for scattered starlight. The blue - green regions of the Horsehead Nebula correspond to regions not shadowed from the light from the stars in the H II region to the top of the picture and scatter stellar radiation towards the observer; these are thus 'mountains' of dust

At the second stage the particles have formed large clumps, roughly 100 kilometers across and, similar to the asteroid Lutetia. These bodies in turn formed the rocky planets including the Earth, shown in the third panel down.

Gamma Ray Burst - Artist view - Gamma Ray Burst - Artist view - Artist view of a gamma burst, a powerful and brief emission of gamma rays whose origin is linked either to the collision of two neutron stars or to the death of a hypermassive star. Gamma - ray bursts (GRBs) are powerful flashes of energetic gamma - rays lasting from less than a second to several minutes. They release a tremendous amount of energy in this short time making them the most powerful events in the Universe. They are thought to be mostly associated with the explosion of stars that collapse into black holes. In the explosion, two jets of very fast - moving material are ejected, as depicted in this artist's illustration. If a jet happens to be aimed at Earth, we see a brief but powerful gamma - ray burst

This artist's impression shows an event in the early history of the Solar System that may explain how the unusual asteroid Lutetia came to now be located in the main asteroid belt, between Mars and Jupiter. Lutetia is seen passing close to one of the very young rocky planets about four billion years ago and having its orbit drastically altered. Its unusual spectral properties indicate that Lutetia started life as a fragment of the material that was forming the inner planets but it is now found to be an interloper much further from the Sun

A gravitational arc is visible at the bottom of the image. This is the deformed image of a galaxy farther away behind the cluster. This cluster hosts one of the most prominent gravitational arcs known to date. The light of a very remote object is deformed by the foreground cluster. Abell 370, at the center of the photo, contains a large number of galaxies - most of them are ellipticals. The two brightest red galaxies slightly above the gravitational arc are the most massive in the cluster and give an important contribution to the lensing event. This gravitational arc - in combination with the cluster of galaxies - provides a natural laboratory to study the physics of gravity. The exact shape of the arc allows to estimate the mass of the cluster through the equations of general relativity

On images obtained at optical wavelengths, thick dust layers almost completely obscure the galaxy's centre. Until 1949, NGC 5128 was thought to be a strange object in the Milky Way, but it was then identified as a powerful radio galaxy and designated Centaurus A. The distance is about 10 - 13 million light - years (3 - 4 Mpc) and the apparent visual magnitude is about 8, or 5 times too faint to be seen with the unaided eye. There is strong evidence th

Planetary system around Trappist-1 - Artist's impressions of the TRAPPIST-1 planetary system: Artist's view of extrasolar planets around the red dwarf star TRAPPIST-1. At least seven exoplanets the size of the Earth are orbiting this star 40 light years ago in the constellation Aquarius. All could contain water. This artist's impression shows several of the planets orbiting the ultra-cool red dwarf star TRAPPIST-1. New observations, when combined with very sophisticated analysis, have now yielded good estimates of the densities of all seven of the Earth-sized planets and suggest that they are rich in volatile materials, probably water
