![]() Together, they prove the burst was 70 times brighter than any yet seen.īurns and other scientists presented new findings about the BOAT at the High Energy Astrophysics Division meeting of the American Astronomical Society in Waikoloa, Hawaii. They then compared the results with those from the Russian team working on Konus data and Chinese teams analyzing observations from the GECAM-C detector on their SATech-01 satellite and instruments on their Insight-HXMT observatory. scientists were able to reconstruct this information from the Fermi data. The burst was so bright it effectively blinded most gamma-ray instruments in space, which means they could not directly record the real intensity of the emission. NASA’s Goddard Space Flight Center and Adam Goldstein (USRA) Their answer: once in every 10,000 years. He led an analysis of some 7,000 GRBs – mostly detected by NASA’s Fermi Gamma-ray Space Telescope and the Russian Konus instrument on NASA’s Wind spacecraft – to establish how frequently events this bright may occur. ![]() “GRB 221009A was likely the brightest burst at X-ray and gamma-ray energies to occur since human civilization began,” said Eric Burns, an assistant professor of physics and astronomy at Louisiana State University in Baton Rouge. After combing through all of this data, astronomers can now characterize just how bright it was and better understand its scientific impact. The burst triggered detectors on numerous spacecraft, and observatories around the globe followed up. The closer to head-on we view one of these jets, the brighter it appears.ĭownload high-resolution video and images from NASA’s Scientific Visualization Studio.Ĭredit: NASA’s Goddard Space Flight Center They then plow into material surrounding the doomed star and produce a multiwavelength afterglow that gradually fades away. These jets pierce through the star, emitting X-rays and gamma rays (magenta) as they stream into space. The black hole then drives jets of particles that drill all the way through the collapsing star at nearly the speed of light. Astronomers think most occur when the core of a massive star runs out of nuclear fuel, collapses under its own weight, and forms a black hole, as illustrated in this animation. ![]() Gamma-ray bursts are the most luminous explosions in the cosmos. ![]()
