How We Accidentally Discovered Gamma-Ray Bursts

Gamma-ray bursts (GRBs) are powerful explosions of gamma radiation from outside the Milky Way. Discovered accidentally during the Cold War by Vela satellites, GRBs have puzzled scientists for over 50 years. Initial detections in the 1960s and 70s revealed their mysterious nature, but it wasn't until the launch of BeppoSAX in 1996 that significant progress was made. BeppoSAX helped pinpoint GRB locations, confirming they originate far outside our galaxy. Despite advancements, the exact causes of GRBs remain unclear, with theories involving supernovas and merging neutron stars. GRBs are unpredictable due to their occurrence on cosmological time scales. However, understanding their interaction with Earth helps protect satellites and astronauts. The journey of GRB research continues, offering insights into the universe's habitability.
