Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.195—so far away that its light has been traveling for roughly 11.7 billion years. The study, published in The Astrophysical Journal on Aug. 13, offers a close-up look at how massive stars die in the young universe's primitive, metal-poor conditions.
