Huge gamma-ray burst collection 'rivals 250-year-old Messier catalog'

Hundreds of gamma-ray bursts (GRBs) have been recorded as part of an enormous global effort so extensive it 'rivals the catalog of deep-sky objects created by Messier 250 years ago', astronomers say. GRBs are the most violent explosions in the Universe, releasing more energy than the Sun would in 10 billion years. They occur when either a massive star dies or two neutron stars merge.
