SN 1998bw

SN 1998bw is a supernova—a massive star explosion—discovered in 1998. It is notable because it coincided with the gamma-ray burst GRB 980425, linking certain supernovae to these intense cosmic energy releases. SN 1998bw was unusually energetic and bright, indicating a particularly powerful explosion likely involving a collapsing massive star forming a black hole. This event helped scientists understand the connection between the death of massive stars and gamma-ray bursts, contributing to our knowledge of stellar evolution and high-energy astrophysical phenomena.
