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.

The chronology of the universe describes the history and future of the universe according to Big Bang cosmology.. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
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]
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 ...

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 ...
This includes the most distant spectroscopically confirmed supernova at a redshift of 3.6, indicating its explosion occurred when the universe was merely 1.8 billion years old. These findings [42] offer crucial insights into the early universe's stellar evolution and the frequency of supernovae during its formative years.
