Some high energy astronomy bits

NASA’s Swift satellite has captured its 500th Gamma Ray Burst. The burst, which was discovered by an astrophysicist combing the data for signals too weak for the automatic signal to pick up, occurred in the constellation of Cassiopeia. The burst was a long sort, believed to be due to the death of a massive star 95% of the age of the universe ago. More detail, lots of videos and a run down of some of the most interesting GRBs found by Swift are all here in a page celebrating the discovery.

Not to be outdone, the Chandra X-ray Space Telescope has a new webpage up on neutron stars and supernova remnants – a question and answer session in which anyone can participate.
