Jul 29  Infalling gas in the heart of NGC 3115
Using the Chandra space telescope, astronomers at the University of Alabama led by Ka-Wah Wong have photographed and analysed, in unprecedented detail in the X-ray domain, the flux of gas falling >>>
Jul 28  Leo's Triplet as seen by the VST
A spectacular demonstration of the power of the new VLT Survey Telescope (VST), and its camera, OmegaCAM, has arrived from the European Southern Observatory. The proof is this extremely wide >>>
Jul 27  Ring galaxies: Auriga's Wheel
Amongst the most spectacular and rare galaxies known are the so-called "ring galaxies", the best known examples being the Cartwheel Galaxy, UGC 7069, and Hoag's object (large image >>>
Jul 26  A new planetary nebula for Kepler
Using the 2.1 metre telescope of the Kitt Peak National Observatory, the Australian researcher Orsola De Marco and her Ph.D. student Dimitri Douchin (Macquarie University, Sidney) have confirmed >>>
Jul 22  A dive into the stars of M31
It is becoming common nowadays to discover something new and interesting while searching through archival data from the world's great telescopes. The 4 images above were taken by the Hubble Space >>>
Jul 21  New satellite of Pluto discovered
During an observing campaign aimed at searching for possible rings around Pluto, a team of researchers led by Mark Showalter (SETI Institute, Mountain View, California) using the Wide Field Camera >>>
Jul 18  Brown dwarfs near the Sun
There is no doubt that Proxima Centauri, at a distance of 4.2 light years from the Sun, is the closest star. However, it is less certain which is the closest brown dwarf (though they are probably black or >>>
Jul 15  Ladies and Gentlemen... Vesta!
Finally we can see the real face of Vesta, asteroid number 4, discovered on 29th March 1807 by Olbers. It was photographed on 9th July by the Dawn probe, after a journey of almost four years that >>>
Jul 14  Two very close white dwarfs
Around 20 binary systems, made up of two white dwarfs that orbit very close to each other, have been discovered so far, but the latest, identified by a research team led by Warren Brown (Harvard >>>
Jul 13  Neptune, one orbit after its discovery
Yesterday, Neptune was in approximately the same point in its orbit as when it was officially discovered on 23rd September 1846. In other words, 1 Neptunian year (165 terrestrial years) have passed. To >>>
Jul 12  Chinese space station ready to go
Within a few months China will launch the first module of its own space station. This important new milestone reached by the Asian super-power, after the first manned orbital flight in 2003, the first lunar >>>
Jul 11  More anti-clockwise galaxies in the north?
The hypothesis that the Big Bang was a symmetric event with an initially uniform expansion that caused the whole Universe to be isotropic on large scales, has today been put into question by a >>>
Jul 8  Revealed: the origin of primordial dust
Thanks to observations made with the Herschel space telescope of the supernova 1987A, it seems that an explanation may have been found as to why very distant, and so very young, galaxies are found >>>
Jul 7  Hydrogen peroxide in the Rho Ophiuchi nebula
Useful as a disinfectant and an old way of bleaching your hair, hydrogen peroxide (H2O2) has now been found for the first time in interstellar space, within the nebula that surrounds the star Rho >>>
Jul 6  1 million observations for Hubble!
On 4th July, national holiday in the US, the Hubble Space Telescope reached an impressive milestone: 1 million science observations! The millionth observation was of the extrasolar planet HAT-P-7b, a >>>
Jul 5  To find aliens look for sulphur
Even though, among the many planetary systems known, we have not managed to find a planet that resembles the Earth very closely, there are already some fairly clear ideas about what we should look >>>
Jul 4  Martian rust covers traces of water
In recent years several small concentrations of carbonate minerals have been found on the surface of Mars. These minerals are of special interest because their formation is connected to the presence of >>>
Jul 1  The first galaxies: new evolutionary picture
The formation of new stars in primordial galaxies, and their subsequent growth, are not directly linked to the merger of smaller galaxies, as previously thought, and this process may not even be the main >>>
