GRB 221009A was an extraordinarily bright and very energetic gamma-ray burst (GRB) jointly discovered by the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope on October 9, 2022. The gamma-ray burst was ten minutes long, [1] but was detectable for more than ten hours following initial detection.
In December 2022, astronomers reported the observation of GRB 211211A for 51 seconds, ... Assuming the gamma-ray explosion to be spherical, ...
[1] [2] It is one of the most extreme gamma-ray bursts ever recorded, [3] and was the most energetic gamma-ray burst ever recorded, until GRB 221009A was recorded in 2022. The explosion had the energy of approximately 9000 type Ia supernovae if the emission was isotropically emitted, and the gas jets emitting the initial gamma rays moved at a ...
