Scientists have analyzed the brightest gamma-ray burst (GRB) ever detected, named the BOAT (Brightest Of All Time) and GRB 221009A, which was observed by NASA's Fermi and Swift satellites in October last year. The event is at least ten times brighter than any previously seen GRB. The data collected
Gamma-ray bursts, or GRBs, are the most powerful explosions in the universe, and this event, officially named GRB 221009A, is at least 10 times brighter than anything NASA’s Swift mission has seen before.
He continued: “By studying the evolution of this astonishingly bright GRB in great detail, we can learn a lot about the physics of a blast wave. “This was the first indication that this was an unusual event,” explains Dr. Kim Page, a member of the Swift team at the University of Leicester, “Swift simply doesn’t trigger on GRBs an hour old! In fact, at first, we thought this must be some other event, an explosion in our own galaxy, for example.”
Dr. Phil Evans added: “Even after 18 years of operation, Swift can still surprise us with something unexpected, awesome, and scientifically powerful, and it can still challenge us – those dust rings may look pretty but they gave us some headaches, they really complicated the data analysis! Even with those complications, though, this event gives us an opportunity to study a GRB in unprecedented detail.
