GRB (Gamma-Ray Bursts)

Gamma-Ray Bursts (GRBs) are intense flashes of gamma rays—the most energetic form of light—lasting from seconds to minutes. They occur when massive stars exhaust their fuel and collapse into black holes or neutron stars, often following a supernova explosion. This process releases a focused jet of energy, illuminating the universe with a brief but extremely powerful burst of gamma rays. GRBs are critical for understanding extreme cosmic events, and their observations help scientists study the early universe, star formation, and the nature of black holes.
