Explore the discovery history of cosmic gamma-ray bursts, from 1960s Vela satellites to modern understanding of their origins.
0 views
Cosmic gamma-ray bursts (GRBs) were first detected in the late 1960s by the Vela satellites, designed to monitor compliance with the nuclear test ban treaty. These bursts are brief but intense flashes of gamma radiation, representing some of the most energetic events in the universe. Further research in the 1990s using space observatories has helped understand their origins, often linked to supernovae or the merging of neutron stars.
