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.
Illustration of a short gamma-ray burst caused by a collapsing star. [160] No gamma-ray bursts from within our own galaxy, the Milky Way, have been observed, [161] and the question of whether one has ever occurred remains unresolved. In light of evolving understanding of gamma-ray bursts and their progenitors, the scientific literature records ...
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.

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 brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.
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]
