JWST reveals likely Type II supernova from when universe was only 2 billion years old
Filed by Dr. Kai Vega
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.
