The explosion had the energy of approximately 9000 type Ia supernovae if the emission was isotropically emitted, and the gas jets emitting the initial gamma rays moved at a minimum velocity of approximately 299,792,158 m/s (99.9999% the speed of light), making this blast one of the most extreme recorded.

Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars. This radiation is emitted across the electromagnetic spectrum almost uniformly, from X-rays to the far ...
Gamma-ray bursts are thought to be highly focused explosions, with most of the explosion energy collimated into a narrow jet. [ 94 ] [ 95 ] The jets of gamma-ray bursts are ultrarelativistic , and are the most relativistic jets in the universe.
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 ...
GRB 221009A came from the constellation of Sagitta and occurred an estimated 1.9 billion years ago, [14] however its source is now 2.4 billion light-years away from Earth due to the expansion of the universe during the time-of-flight to Earth. [15]
Now new research claims to have shown that the explosion is in fact a nearly perfect sphere, and is completely symmetrical. Scientists have pursued a number of possible explanations – such as ...
Most luminous SMSS J215728.21-360215.1: Absolute magnitude of −32.36 Highest absolute magnitude discovered thus far. Most powerful quasar radio source 3C 273: Also the most powerful radio source in the sky Most powerful SMSS J215728.21-360215.1: Most variable quasar radio source QSO J1819+3845 (Q1817+387) Also the most variable extrasolar ...
The solar system might have been hit by the brightest explosion ever seen, scientists have said. The pulse of intense radiation began its life in a cosmic explosion two billion light years away ...
