Scientists monitor the largest explosion in space that swept the Earth
In a thrilling incident, astronomers have detected the most powerful space explosion ever. A gamma-ray burst, called GRB221009A, was detected on October 9, and even its afterglow is brighter than most objects in space.
According to science newscientist, this type of gamma ray burst (GRB) is believed to occur when a massive star explodes in a supernova, leaving behind a black hole, where the explosion creates an unusual jet of light that makes up the GRB itself. Hence the supernova causes a faint glow.
This type of GRB appears bright in part because it is about 2.4 billion light-years from Earth, making it one of the closest and brightest GRBs ever observed.
"If we look at all the gamma-ray bursts that have been detected, these are separate bursts...informally, we'd call it BOAT, the brightest of all," said Gillian Rastingad of Northwestern University in Illinois. She and her colleagues calculated that the GRB from This brightness is expected to occur only once every thousand years or so.
It is not known exactly how powerful this explosion was, despite the fact that many telescopes around the world looked at it, but because it was so bright that it saturated the detectors of gamma ray telescopes, all it was seen were completely white pixels without any specific detail, according to the One of Rastingad's colleagues, Andrew Levan of Radboud University in the Netherlands, said.
“If you have gamma ray eyes, you will go blind,” Levan explained, with current estimates putting the GRB energy between 10^54 and 10^55 ergs, he says. About 10^51 ergs.
Navy radio transmitters have recorded a strange turbulence in the upper atmosphere, which appears to be caused by the strong light from the GRB hitting it, and detectors looking for high-energy photons "particles of light" have also seen unusual particles with much higher energies than anything. Produced in the Large Hadron Collider.
“It seems pretty much every telescope in the world is starting to look at the explosion,” Rastingad said, but to learn more about the supernova itself and its parent galaxy, those interested will have to wait for the bright jet to fade, which could take months. To have a better idea of why the GRB is so unusually bright, scientists say.
