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.

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.
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.

A large fire caused a series of smaller but powerful explosions that continued until 2 a.m. the next day. The explosions could be heard as far away as the Macedonian capital of Skopje, 170 km (110 mi) away.[1] There were 26 killed, 318 houses were destroyed completely, 200 buildings were seriously damaged, and 188 buildings were less seriously ...
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]
