GLAST Science Operations Underway – Now, About That Name…
After a 60-day checkout period, science operations have begun in earnest for GLAST, the Gamma ray Large Area Space Telescope, which is now surveying the gamma-ray sky. Launched on June 11, 2008, the GLAST spacecraft has been undergoing calibrations of the two instruments on board, the LAT (Large Area Telescope) and the GBM (GLAST [...]

Astronomers Discover a Supernova/Gamma Ray Burst Hybrid
Just when we thought we were beginning to understand what supernovae and gamma ray bursts were all about. Astronomers have just uncovered the true nature of what they thought was a regular supernova observed in January. At the time, it looked like a supernova emitting a 5-minute long burst of X-rays. But these X-rays were [...]

See that Record Breaking Gamma Ray Burst Go! (Video)
No sooner had NASA's Swift X-Ray Telescope caught the afterglow of the record-breaking Gamma Ray Burst (GRB) on Wednesday (March 19th), the worlds telescopes swung toward the constellation of Boötes to watch the afterglow of this massive explosion. One instrument in a Chile observatory was observing in Swift's field of view at the time of [...]

Biggest Ever Cosmic Explosion Observed 7.5 Billion Light Years Away
A record-breaking gamma ray burst was observed yesterday (March 19th) by NASA's Swift satellite. After red-shift observations were analysed, astronomers realized they were looking at an explosion half-way across the Universe, some 7.5 billion light years away. This means that the burst occurred 7.5 billion years ago, when the Universe was only half the age [...]

Looking Down the Barrel of A Gamma Ray Burst
A team of astronomers from the University of Sydney in Australia have been keeping an eye on a binary star system called Wolf-Rayet 104, located in the constellation Sagittarius. Wolf-Rayet stars are hot, gargantuan, older stars that are losing their masses, and astronomers consider these stars as ticking bombs: they could go supernova [...]

A Powerful Blast From the Distant Past
As sure as the Sun rises, you can expect that astronomers are going to beat their records. Today, we can wave goodbye to the record for the most distant short-duration gamma ray burst. Astronomers working with NASA have announced a newly discovered explosion that occurred 7.4 billion light years away. That's nearly double the distance [...]
