The NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 revealed the infrared afterglow (circled) of gamma-ray burst 221009A and its host galaxy, seen nearly edge-on as a sliver of light extending to upper right from the burst. This animation flips between images taken on 8 November and 4 December 4 2022, one and two months after the eruption. Given its brightness, the burst’s afterglow may remain detectable by telescopes for several years. Each picture combines three near-infrared images taken at wavelengths from 1 to 1.5 microns and is 34 arcseconds across.
