Astronomers observe brightest flash of light ever seen, from an event that occurred 2.4 billion light years from Earth and was likely triggered by the formation of a black hole
Picture provided by NASA on October 14, 2022, shows Swift’s X-Ray Telescope capturing the afterglow of GRB 221009A about an hour after it was first detected.
The burst of gamma-rays -- the most intense form of electromagnetic radiation -- was first detected by orbiting telescopes on October 9, and its afterglow is still being watched by scientists across the world. The star explodes in a supernova, collapses into a black hole, then matter forms in a disk around the black hole, falls inside, and is spewed out in a jet of energy that travels at 99.99 percent the speed of light.
