View Full Version : Closest Gamma Ray Burst Ever Discovered

2005-Oct-23, 06:21 AM
SUMMARY: Gamma ray bursts (GRB) are the largest known explosions in the Universe; immensely powerful, quick to fade, but usually incredibly far away. Astronomers with the National Radio Astronomy Observatory got lucky, though, when they analyzed a recent GRB and discovered it was only 2.6 billion light-years away (most are usually 4 times more distant). What causes these bursts is a mystery, but the theories usually incorporate black holes in some catastrophic way - colliding into another black hole; wrapping a magnetic field like a spring, etc. This close burst didn't answer the mystery, but it did allow the astronomers to rule out one idea, that material from a GRB blasts out like "cannonballs".

The question which has been in my mind since I read about Gamma Ray, is that what are thier emanates in the space? explosion of massive star , born of baby blackhole, or galixies collision?

Hey, I did a presentation on GRB's on Friday. :) I drew pretty pictures of both processes.
