GRB 980425

GRB 980425 was a gamma-ray burst (GRB) that was detected on 25 April 1998 at 21:49 UTC. A gamma-ray burst is a highly luminous flash associated with an explosion in a distant galaxy and producing gamma rays, the most energetic form of electromagnetic radiation, and often followed by a longer-lived "afterglow" emitted at longer wavelengths (X-ray, ultraviolet, optical, infrared, and radio). GRB 980425 occurred at approximately the same time as SN 1998bw, providing the first evidence that gamma-ray bursts and supernovae are related.
