The gamma-ray burst was ten minutes long, [1] but was detectable for more than ten hours following initial detection. [2] [3] Despite being around 2.4 billion light-years away, it was powerful enough to affect Earth's atmosphere, having the strongest effect ever recorded by a gamma-ray burst on the planet.
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 ...
GRB 080916C is a gamma-ray burst (GRB) that was recorded on September 16, 2008, in the Carina constellation and detected by NASA's Fermi Gamma-ray Space Telescope. The burst lasted for 23 minutes (1400 s). [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 ...
Dozens of telescopes all over the world are pointing at a patch of sky that gave rise to the most powerful gamma-ray burst ever seen, hoping to shed more light on processes that birth black holes.
The brightest gamma ray burst ever detected recently reached Earth. It’s 70 times longer than any other burst we’ve spotted.
Either a long-duration burst in which the presence of a bright supernova is ruled out, or a short-duration burst with extremely long-lasting gamma-ray emission. GRB 080319B: z = 0.937: Swift: The most (optically) luminous event of any nature observed in the universe to date. By far the brightest optical afterglow of any gamma-ray burst. GRB 080916C
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]
GRB 200522A is believed to have been formed when two neutron stars collided and exploded, creating an extremely large and bright short-ray gamma burst.The brightness of the emission was 10 times that of predicted, and was around 10,000 times more powerful than the sun in its entire 10 billion year lifetime.
