In 2019, the NASA/ESA Hubble Space Telescope saw a supernova, nicknamed Supernova Requiem, in a distant galaxy named MRG-M0138. Now seven years later, the James Webb Space Telescope has detected another gravitationally lensed supernova within the same galaxy, marking the first-ever instance of two gravitationally lensed supernovae in a single galactic host.
