May 31  A new stellar population in globulars
Globular cluster, enormous groupings of hundreds of thousands of stars, that preferentially populate the outer regions of our galaxy and many others, are amongst the most ancient structures in the >>>
May 27  Mission over for Spirit
It was supposed to remain operational for only 90 days, but instead it worked for over 6 years, producing a huge quantity of images and data that will be the subject of study for a long time to come. An >>>
May 26  A solitary super-star in the Tarantula
An enormous star, 150 times more massive than the Sun, has been discovered in the Large Magellanic Cloud, and it appears to be alone, with no other stars in its vicinity. This is very unusual, because >>>
May 25  Student finds some missing mass
By re-reducing data contained in the ROSAT All-Sky Survey, of an area including the 2 degree Field Galaxy Redshift Survey (2dFGRS), Jasmina Lazendic-Galloway, Amelia Fraser-McKelvie and Kevin Pimbblet >>>
May 24  V1, the star that enlarged the Universe
A collaboration between the Space Telescope Science Institute and the American Association of Variable Star Observers (AAVSO) has produced a series of observations of the variable star "V1", that >>>
May 23  The Jets of Centaurus A in high resolution
Using a network of 9 radio telescopes called TANAMI (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) a group of researchers, led by Cornelia Mueller (University of Erlangen >>>
May 19  A multitude of planets without stars
The existence of vagabond planets, that have lost the gravitational link with their host star after an interaction within the planetary system, now seems certain. What still remains very uncertain is how >>>
May 18  A new look at planet Gliese 581 d
The planetary system around the star Gliese 581, just 20 light years away, finds itself ever more at the centre of attention of astronomers in search of planets that could support life. In 2007 two planets >>>
May 17  The Anthropocene: really an epoch?
That a planet can conserve traces of long extinct life is clear from the presence of fossils on the Earth. Many have searched for evidence of some kind of fossil also on Mars, and in the future we hope to >>>
May 16  Green Bank Telescope looks for ET
The impressive list of planet candidates created by NASA's Kepler space telescope, 1235 to date, has given new impetus to the search for life in the Cosmos. Recently, the Allen Telescope Array (ATA), >>>
May 13  The crystalline surface of Haumea
Haumea is one of the four dwarf planets so far discovered beyond the orbit of Neptune; the others are Pluto, Eris and Makemake. There are other candidates, such as Quaoar, but it seems that this is too >>>
May 12  The first image of Vesta from Dawn
NASA's Dawn probe has started "setting its sights" for its forthcoming rendez-vous with Vesta (the second largest asteroid) set for 16th July 2011, when both objects will be 188 million km from the Earth. >>>
May 11  Unexpected isotopes in the solar wind
The first findings of NASA's Genesis probe have just been published in the "Proceedings of the National Academy of Sciences", and the results are surprising. The mission involved the launch of a probe >>>
May 10  2010 SO16, a relic of the Earth
Observations continue of an unusual, small asteroid, 2010 SO16, discovered by the infrared satellite WISE. Because of its large proper motion (left), the magnitude 20.7 object was immediately classed >>>
May 9  The most ancient mineral
Once again a new mineral has been discovered in a meteorite. The last example was "Wassonite", made up of sulphur and titanium, found in an Antarctic chondrite. The new mineral, called "Krotite" (in >>>
May 6  Comet Elenin: will it be spectacular?
Of all the comets that reach naked eye visibility, the most spectacular are the long period comets, coming from the remotest parts of our solar system, well beyond the orbit of the most distant planet. >>>
May 5  Gravity Probe B confirms Einstein
"Imagine the Earth as if it were immersed in honey. As the planet rotated on its axis and orbited the Sun, the honey around it would warp and swirl, and it's the same with space and time." This is how >>>
May 4  IceCube detects cosmic ray sources
As mentioned in a previous news article, the neutrino observatory IceCube, situated in the Amundsen-Scott South Pole Station, has been fully operational since last December and its results are being >>>
May 3  Hale-Bopp photographed at 30.7 AU!
Who doesn't remember that magnificent comet that lit up the skies during the first months of 1997, becoming one of the most spectacular of the last century? It was comet Hale-Bopp (C/1995 O1), and >>>
May 2  Crater chains on Mercury
Images of Mercury's surface continue to arrive from NASA's MESSENGER probe (MErcury Surface, Space ENvironment, GEochemistry, and Ranging), after reaching stable orbit about >>>
