The JWST has identified a supernova from only 730 million years after the Big Bang, a record-breaking distance. This supernova is linked to a gamma-ray burst detected in March 2025. The discovery allows scientists to study individual stars in the very early universe. This finding surpasses the JWST's previous most distant supernova and offers insights into star formation during the universe's reionization era.
