Supernova 1998bw

Supernova 1998bw was a powerful stellar explosion observed in 1998, notable for its association with a gamma-ray burst, making it one of the first linked events of this kind. It resulted from a massive star collapsing into a black hole, releasing immense energy and ejecting material at speeds close to that of light. This explosion was unusually energetic—classified as a hypernova—and helped scientists understand the connection between such massive stellar deaths and high-energy cosmic phenomena. Its detailed study provided valuable insights into the life cycle of massive stars and the origins of some of the universe's most energetic events.
