Hubble Spots Distant Supernova in Gemini, Enhancing Cosmic Distance Studies

The NASA/ESA Hubble Space Telescope has captured a stunning image of SN 2022aajn, a Type Ia supernova in the constellation Gemini. Located 600 million light-years away, the explosion was first detected in November 2022. Type Ia supernovae serve as essential cosmic distance markers due to their predictable brightness. Hubble’s observations, part of a broader survey of 100 supernovae, use mult
