Gamma Ray Burst from Nowhere!

The current theory holds that that gamma ray bursts like GRB 070125 are given off by super-jumbo-sized stars that run out of fuel and violently collapse to form black holes, explains Neil Gehrels, principal investigator of NASA’s Swift telescope.

Such huge stars can only be created in very gas and dust-rich parts of galaxies where lots of other stars are also being born. So it makes no sense to find such a star living and dying in the empty space between galaxies.

Yet another space nasty to worry about. If it doesn’t come from a star we can see, then the possibility exists that we can be zapped from one that is either a star we cannot see, or not a star at all. More at Discovery.com
