The fading afterglow of GRB 190114C and its home galaxy were imaged by the Hubble Space Telescope in February and again in March. The difference between the images reveals a faint, short-lived glow (centre of the green circle) located about 800 light-years from the galaxy’s core. Credit: NASA, ESA, and V. Acciari et al. 2019
