Astronomers have spotted what may be the most powerful explosion ever seen. The gamma ray burst, called GRB 221009A, was spotted on 9 October, and even its afterglow is brighter than most objects in the sky. is thought to occur when a massive star explodes in a supernova, leaving behind a black hole. The explosion creates an extraordinary jet of light which makes up the GRB itself, and then the supernova causes a dimmer afterglow.
This has made a splash among astronomers. “It seems like pretty much every telescope in the world is starting to look at it,” says Rastinejad. But to learn more about the supernova itself and its home galaxy, they will have to wait until the bright jet fades, which could take months. Once that occurs, we should have a better idea of why this GRB was so extraordinarily bright.More on these topics:
