Gamma-Ray Bursts with Record Energy (IMAGE) Deutsches Elektronen-Synchrotron DESY Caption Gamma-ray bursts can be triggered by the explosion of a super massive star, collapsing into a black hole. From the vicinity of the black hole, powerful jets shoot in opposite directions into space, accelerating electrically charged particles, which in turn interact with magnetic fields and radiation to produce gamma rays.
