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.
GRB 080319B was a gamma-ray burst (GRB) detected by the Swift satellite at 06:12 UTC on March 19, 2008. The burst set a new record for the farthest object that was observable with the naked eye: [2] it had a peak visual apparent magnitude of 5.7 and remained visible to human eyes for approximately 30 seconds. [3]
It is the most energetic gamma-ray burst ever recorded. It has been deemed to be the "B.O.A.T.", or Brightest Of All Time. It had the highest fluence and peak flux ever identified, by a large margin. [14] It also holds the record for highest energy burst recorded if released isotropically, beating GRB 080916C. [14]
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.

Astronomers have spotted a record-breaking gamma ray burst, the most energetic type of electromagnetic explosion in the universe. ‘Most powerful explosion ever’ detected by telescopes Skip to ...
The total energy of typical gamma-ray bursts has been estimated at 3 × 10 44 J, – which is larger than the total energy (10 44 J) of ordinary supernovae (type Ia, Ibc, II), [103] with gamma-ray bursts also being more powerful than the typical supernova. [104] Very bright supernovae have been observed to accompany several of the nearest GRBs ...
At 15:44:06 UT on 7 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230307A . [6] at the same time, the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor light curve shows a roughly fast rise and exponential decay (FRED) shape with a possible precursor, with a total duration of ~100 sec.
