Submission + - Cosmic explosion detonates in empty space

Six spacecraft around Earth and Mars detected a powerful volley of gamma rays lasting about a minute on 25 January 2007. Such explosions, called long gamma-ray bursts, are thought to be caused when massive stars explode and their cores collapse into black holes.

But follow-up observations by some of the world's most powerful telescopes failed to turn up any sign of a 'host' galaxy for the dying star. Spectral observations did show, however, that the burst, called GRB 070125, had exploded within a small pocket of dense gas.
