 Space & Cosmology Vast stars fed biggest black holesThursday, 5 November 2009
Stars more than one million times as massive as the Sun may be more stable than astronomers thought, and have created seeds that grew into the largest supermassive black holes.  Astronomers see universe's cosmic skeletonWednesday, 4 November 2009
Astronomers in Chile and Japan have for the first time seen part of the "cosmic web" of galaxies that permeates the known universe in a gigantic assembly some seven billion light-years from Earth.  New probe to help predict extreme weatherTuesday, 3 November 2009
A water tracking satellite launched by the European Space Agency is designed to help give faster predictions of floods and other extreme weather incidents caused by climate change.  Gamma-ray burst is the most distant object ever observedFriday, 30 October 2009
It took 13 billion years to reach Earth, but astronomers have seen the light of an exploding mega-star that is the most distant object ever detected, two studies report.  Wireless tech wins Prime Minister's PrizeWednesday, 28 October 2009
