WebThanks to its extremely wide detection region in the MeV energy range, Insight-HXMT made an unambiguous measurement of GRB 221009A for its precursor and early afterglow, according to Zhang Shuangnan, the project’s principal investigator. Web29 mrt. 2024 · The event, dubbed GRB 221009A, was detected on Oct 9 last year, and it came from the constellation of Sagitta at a distance of around 2.4 billion light-years from Earth. Despite the distance, the burst was so bright that it temporarily blinded several space instruments and disturbed Earth's atmosphere.
