Beams from brightest gamma ray burst ever seen were pointed directly at Earth

Gamma-ray bursts are so powerful they could vaporize the Earth from 200 light-years away. Gamma-ray bursts are thought to occur when a massive star runs out of nuclear fuel and its core collapses. Now, NASA has announced that on 9 October 2022, satellites detected an extremely bright gamma-ray signal that suddenly exploded from the constellation of Sagitta; it lasted hundreds of seconds.
