Description
The sudden, intense outburst and explosion of gamma ray in the depths of the universe is known as GRB (Gamma Ray Burst).This phenomenon was known for decades as one of mysterious astronomical phenomena. Today it has been known that some of these explosions are relevant with supernovae, and other related to magnetars(which is a type of neutron star with a very strong magnetic field).Discovery of these explosions dates back to the 1960s.At this time a number of military satellites that detected nuclear explosions by the United States of America were thrown into the atmosphere, instead of detecting nuclear explosions on the Earth found more powerful explosion on its back in the depths of the cosmos. By 1990 none of the sources of this radiation was discovered and the only thing scientists knew about them was that they originate from outer spaces of our atmosphere. GRBs are divided into three groups:long-gamma rays burst, short- gamma ray burst and a tiny subset.
