The explosion called GRB 221009a released photons with 18 energy teraelectron (an 18 followed by 12 zeros) – a record – and had an impact on long wave communications in the earth’s atmosphere.

This is the brightest flash of light ever observed by astronomers. It was emitted at a distance of 2.4 billion light years from the earth, and detected on Sunday October 9, especially by the Fermi Gamma-Ray Space Telescope of NASA, the SWIFT telescope. Astronomers discovered that it was a gamma start, one of the most violent explosions in the universe. This light eruption, called GRB 221009A (GBR is the acronym of Gamma Ray Burst, gamma start in English), was caused by the birth of a black hole and its residual light continues to be studied.

Scientists believe that these eruptions, which last several minutes, are provoked by the death of giant stars, more than thirty times the size of the sun, explained the AFP agency (AFP) the astrophysicist to agency Brendan O’Connor. The star explodes and becomes a supernova, before collapsing on itself and forming a black hole. Of the material then forms a disc around the black hole, is absorbed and rejected in the form of energy traveling at 99.99 % of the speed of light.

The flash has released photons with 18 energy teraelectron (an 18 followed by 12 zeros) – a record – and had an impact on long wave communications in the earth’s atmosphere. “This breaks records, both in the quantity of photons and in the energy of the photons that reach us,” said Brendan O’Connor, who made new observations of the phenomenon, Friday, thanks to the infrared instruments of the telescope From the Gemini South Observatory to Chile. “Something as brilliant, as close, is really an event that we only see once per century,” added the astrophysicist.
“The eruptions of gamma rays in general release in the space of a few seconds the same amount of energy that our sun has produced or will produce during its whole life – and this event is the eruption of gamma rays the more brilliant … “
Evoking an “adrenaline rise” when this kind of event occurs, Brendan O’Connor, who is affiliated with the University of Maryland and at George Washington University, will continue to scrutinize the sky during Next weeks in search of the distinctive signs of the supernovas to confirm their hypotheses on the origin of the flash.
