LA TIMES - Exploding giant star sent longest gamma-ray blast, astronomers say, Apr 17, 2013

Ultra-long gamma-ray burst
 "The most powerful stellar explosion since the big bang has been linked to a newly discovered class of ultra-long gamma ray burst, astronomers said Tuesday at the 2013 Huntsville Gamma-Ray Burst Symposium in Nashville, Tenn. "We really think we’ve found this new class of gamma-ray bursts and a natural explanation for creating them in a type of star collapse that we haven’t previously talked about," said Andrew Levan, an astronomer at the University of Warwick in Coventry, England, who led a study on the phenomena. Gamma-ray bursts are the brightest explosions in the universe, shooting out powerful blasts of high-energy light, and they typically signal the death of a massive star collapsing to form a black hole."
