 Space & Cosmology Icy moon's ocean could support lifeThursday, 25 June 2009
Saturn's icy moon Enceladus harbours a salty ocean under the surface, astronomers have discovered, making it a favourable place for alien life.  Moon probe enters lunar orbitWednesday, 24 June 2009
A space probe that will provide new information about the Moon ahead of future manned missions has entered lunar orbit, four days after launch.  Moon blanket could protect lunar colonyMonday, 22 June 2009
The first astronauts to return to the Moon could be shielded from cosmic and solar radiation with a flexible covering designed by university students.  Kilometre-high waves flow in Saturn's ringsTuesday, 16 June 2009
Cassini has uncovered towering vertical structures in Saturn's seemingly flat rings that are due to the gravitational effects of a small moon.  Dark gamma-ray bursts hidden by space dustMonday, 15 June 2009
Gamma-ray bursts, the universe's most brilliant flashes of light, have revealed areas of star formation previously hidden to astronomers.  Black holes are bigger than we thoughtThursday, 11 June 2009
Supermassive black holes are two or three times more massive than astronomers thought, say supercomputer simulations that add a missing ingredient.  Earth-Mars collision possible, says studyThursday, 11 June 2009
A force known as orbital chaos may cause our Solar System to go haywire, leading to possible collision between Earth and either Venus or Mars.  Megamasers to unravel dark energy mysteryWednesday, 10 June 2009
Accurate measurements of ‘megamasers’ – powerful natural amplifiers of radio waves – will extend the cosmic distance scale and help astronomers understand the nature of dark energy.  Shrinking supergiant puzzles astronomersWednesday, 10 June 2009
A 15-year, continuous observation of the red supergiant Betelgeuse has found that the star, one of the largest known, is shrinking – but astronomers don’t understand why.  One-fifth of us have lost sight of Milky WayTuesday, 9 June 2009
Light pollution has caused one-fifth of the world's population – mostly in Europe and the U.S. – to lose their ability to see the Milky Way in the night sky.  First supernovae blew early galaxies apartWednesday, 3 June 2009
The universe's first stars blew small galaxies apart when they exploded, effectively quashing all nearby star formation, say Japanese astrophysicists.  Space headache: a new health complaint for astronautsWednesday, 3 June 2009
Astronauts who have no history of bad headaches can be prone to disabling attacks while in space, a phenomenon that suggests a new medical condition, say neurologists.  Massive supernova is nearest in five yearsThursday, 28 May 2009
European radio astronomers have discovered the hidden explosion of a massive star, in the nearby galaxy M82.  ESA takes us closer than ever to a black holeThursday, 28 May 2009
Using the XMM-Newton space observatory, astronomers have probed closer than ever to a supermassive black hole lying deep at the core of a distant galaxy.  Hypersonic scramjet passes another test flightSaturday, 23 May 2009
Next-generation aircraft with the potential to dramatically reduce inter-continental travel times are now one step closer after the successful hypersonic flight trials conducted by Australian and U.S. scientists.
