WebDec 7, 2024 · Cambridge, Mass. – Gamma-ray bursts (GRBs) — the most energetic explosions in the universe — come in two varieties, long and short. Long GRBs, which last from two to hundreds of seconds, form when a massive star at least 10 times the mass of our Sun explodes as a supernova. Short GRBs, which last less than two seconds, occur … WebJan 3, 2024 · Gamma Ray Burst Observations.
