James Webb spots supernova from dawn of the universe
Original: James Webb telescope discovers a supernova just 1.1 billion years after the Big Bang
Astronomers using the James Webb Space Telescope have identified a supernova that exploded just 1.1 billion years after the Big Bang, making it one of the earliest stellar explosions ever observed. The detection offers a rare glimpse into the deaths of the first generations of massive stars and could shed light on how the early universe produced its first heavy elements.
Why now: The extreme age of the explosion pushes the boundary of what telescopes can observe about the early universe.
