Gamma bursts were discovered in 1967 by the Vela satellites. Initially designed to monitor compliance with the Nuclear Test Ban Treaty, these satellites detected unexpected bursts of gamma radiation originating from space. Published in 1973, the discovery marked a significant milestone in astrophysics, prompting further research into these powerful cosmic events. Understanding gamma bursts has since provided valuable insights into the most energetic processes in the universe.
