It was so powerful that scientists could still observe the aftereffects of the explosion, dubbed GRB 221009A, hours after it was first detected.Scientists believe the explosion was caused when a star, roughly 2.4 billion light-years away in the Sagitta constellation, collapsed and went supernova before becoming a black hole. The star in question was likely many times larger than our Sun.
“The exceptionally long GRB 221009A is the brightest GRB ever recorded, and its afterglow is smashing all records at all wavelengths,” said Brendan O’Connor, a doctoral student at the University of Maryland and George Washington University in Washington, DC, in a statement. “Because this burst is so bright and also nearby, we think this is a once-in-a-century opportunity to address some of the most fundamental questions regarding these explosions, from theWhen the gamma rays and X-rays from GRB 221009A reached our solar system, they first set off detectors installed on space-based observatories, including NASA's Fermi Gamma-ray Space Telescope, the Neil Gehrels Swift Observatory, and the Wind spacecraft.
The burst also allowed two devices aboard the International Space Station — the Neutron star Interior Composition Explorer X-ray telescope and Japan’s Monitor of All-sky X-ray Image — to work together for the first time to observe GRB 221009A three hours after it was detected.
