Gamma-ray bursts (GRBs) are short-lived, intense bursts of gamma-ray radiation originating from distant regions of the universe. These events are among the most energetic and luminous phenomena observed in the cosmos. GRBs can last from milliseconds to several minutes and are classified into two types: long and short bursts, based on their duration. They are believed to arise from cataclysmic events, possibly the collapse of massive stars into black holes or the merging of neutron stars. While the exact mechanisms behind GRBs remain a subject of ongoing research, their detection provides crucial insights into the early universe, high-energy astrophysics, and the formation of black holes. They serve as cosmic beacons, offering glimpses into extreme cosmic events billions of light-years away.
