Sep 5, 2024 · Gamma-ray bursts (GRBs) are the biggest explosions in the cosmos emitting large amounts of the most energetic form of light, gamma rays. GRBs shine hundreds of times brighter than a typical supernova (the explosive death of a massive star) and are about a million trillion times brighter than the Sun; yet they are short-lived, lasting from a few milliseconds to several minutes.
