  1. GRB 221009A
    • According to 5 sources
    When scientists detected the gamma-ray burst known as GRB 221009A on Oct. 9, 2022, they dubbed it the brightest of all time, or BOAT. Most gamma-ray bursts occur when the core of a star more massive than our Sun collapses, becoming a black hole.
    The brightest burst ever seen, known as GRB 221009A, was first detected on Oct. 9, 2022 by gamma-ray and X-ray telescopes. The likely supernova that caused the burst was 2.4 billion light-years away from Earth.
    In October 2022, an international team of researchers, including Northwestern University astrophysicists, observed the brightest gamma-ray burst (GRB) ever recorded, GRB 221009A.

    Gamma-ray bursts are energetic explosions that go off when a massive star dies and leaves behind a black hole or neutron star ( SN: 11/20/19; SN: 8/2/21 ). The collapse sets off jets of gamma rays zipping away from the poles of the former star. If those jets happen to be pointed right at Earth, astronomers can see them as a gamma-ray burst.
    In early October 2022 a wave of high-energy radiation swept over Earth from a gamma-ray burst, one of the most singularly catastrophic and violent events the cosmos has to offer. Astronomers quickly determined its distance and found it was the closest such burst ever seen: a mere two billion light-years from Earth.
    It’s also possible that an entirely different mechanism launches the very brightest jets into space. The most energetic kind of explosion in the universe, a gamma-ray burst can be spotted billions of light-years away. GRB 221009A was so luminous it effectively blinded most gamma-ray instruments in space when it was detected Oct. 9, 2022.
