Do not let yourself be fooled. The spiral galaxy ESO 580-49 may seem completely calm, but in reality there are hints of explosive activity.
In October 2011, scientists recorded a powerful burst of high-energy gamma rays (gamma-ray burst) from the ESO 580-49 segment. Researchers believe that this galaxy, 185 million light-years distant from us, is a source of gamma radiation.
Such flashes are considered the brightest events in space and can exceed the entire universal gamma-ray output by a few seconds. The reason for their formation in the galaxy (named GRB 111005A) is still unknown. There is an assumption that this is a new explosion event, which has no characteristics yet.
