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]
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.
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. [7] At 2023-03-07T15:44:09Z UT (Solar Orbiter onboard ...
The gamma-ray burst occurred two billion light-years away from Earth. Cosmic explosion that blinded space instruments ‘may be the brightest ever seen’ Skip to main content
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 ...
