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.

Mar 28, 2023 · GRB 221009A has been referred to as the brightest of all time (BOAT). We investigate the veracity of this statement by comparing it with a half century of prompt gamma-ray burst observations. This burst is the brightest ever detected by …

Jul 25, 2024 · In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA’s Fermi Gamma-ray Space Telescope reveals a feature never seen before.

Jun 8, 2023 · Scientists may finally know what made the largest explosion in the universe ever seen by humankind so powerful. Astronomers have discovered that the brightest gamma-ray burst (GRB) ever...

Mar 28, 2023 · Radiation from the explosion — a gamma-ray burst (GRB) known as GRB 221009A — swept over Earth on Oct. 9, 2022. It saturated gamma-ray detectors on multiple space telescopes, earning the...

Oct 28, 2022 · The brightest gamma-ray burst ever recorded recently lit up a distant galaxy — and astronomers have nicknamed it the BOAT, for Brightest of All Time.

Nov 23, 2023 · We argue that the broad-band observations of the brightest-of-all-time (BOAT) GRB 221009A reveal a physical picture involving two jet components: a narrow ($\sim 0.6$ degree half opening angle) pencil-beam jet that has a Poynting-flux-dominated jet composition, and a broader matter-dominated jet with an angular structure.

Apr 12, 2024 · Astronomers have discovered that the BOAT, the most powerful gamma-ray burst ever detected, came from the supernova death of a massive star 2.4 million light-years away.
