NASA’s Webb telescope detects the earliest known supernova from 730 million years after the Big Bang
NASA’s Webb Telescope detects the earliest known supernova, GRB 250314A, 730 million years after the Big Bang, capturing its host galaxy and providing unprecedented early-universe observations.
The Cassiopeia A supernova remnant reveals that massive exploding stars can forge far more of life's essential ingredients ...
