New pics of an old explosion NASA has released a striking new image of explosive neighbouring star Eta Carinae. The star is huge: somewhere between 100 and 150 times the size of our own sun. It is also consuming its fuel at a truly astonishing rate.â¦

News from the galactic centre Astronomers using ESA's Integral gamma-ray observatory have spotted a massive eruption of gamma rays in the galactic centre. The researchers say the characteristics of the flare indicate that it could be an extremely rare star-black hole binary system, exhibiting behaviour that might only be seen once or twice in a decade.â¦

Chandra X-Ray Observatory -- Astronomers have used an X-ray image to make the first detailed study of the behavior of high-energy particles around a fast moving pulsar.     The image, from NASA's Chandra X-ray Observatory, shows the shock wave created as a pulsar plows supersonically through interstellar space...
