The Brightest Explosion Ever Seen

by SpaceRef EditorMarch 30, 2023July 15, 2024
The Hubble Space Telescope’s Wide Field Camera 3 revealed the infrared afterglow (circled) of the BOAT GRB and its host galaxy, seen nearly edge-on as a sliver of light extending to the burst's upper right. This composite incorporates images taken on Nov. 8 and Dec. 4, 2022, one and two months after the eruption. Given its brightness, the burst’s afterglow may remain detectable by telescopes for several years. The picture combines three near-infrared images taken each day at wavelengths from 1 to 1.5 microns.
