Gamma ray flash still ongoing

This artist's image provided by the
University of Warwick  shows a
star being distorted by its close
passage  to a supermassive
black hole at the  center of a galaxy.

  A monster black hole devoured a Sun-like star, producing a long-lasting gamma ray flash.  The star was likely destroyed because it wandered too close to its galaxy’s central black hole, located in the constellation Draco 4 billion light years away.  Earth just happened to get in the way of this stream of gamma rays produced 4 billon years ago.  That 'flash' lasted for months and is still going on now. Gamma ray bursts usually flare up and end in a matter of seconds or milliseconds.
