Gamma-ray bursts (GRBs) were first detected in the late 1960s by U.S. Vela satellites. These satellites were initially launched to monitor compliance with the Nuclear Test Ban Treaty and were equipped to detect gamma radiation spikes from nuclear explosions. Instead, they picked up mysterious gamma-ray bursts from deep space, leading to the discovery of GRBs as astronomical phenomena. These bursts are now known to be the universe's most energetic events, originating from colossal cosmic explosions or mergers of neutron stars.

FAQs & Answers

  1. What are gamma-ray bursts? Gamma-ray bursts (GRBs) are intense flashes of gamma radiation from cosmic explosions and are the most energetic events in the universe.
  2. How do Vela satellites detect gamma-ray bursts? Vela satellites were designed to monitor nuclear tests but unexpectedly detected gamma-ray radiation from space, leading to the discovery of GRBs.
  3. Why are gamma-ray bursts important to astronomy? GRBs provide insights into the universe's most powerful processes, including the formation of black holes and the behavior of neutron stars.
  4. What is the significance of the Nuclear Test Ban Treaty in this context? The Nuclear Test Ban Treaty initiated the launch of Vela satellites, which inadvertently led to the discovery of gamma-ray bursts as cosmic phenomena.
