James Webb Space Telescope has broken its own record and discovered the earliest supernova ever found - when the Universe was only 730 million years old
The NASA/ESA/CSA James Webb Space Telescope has confirmed the source of a super-bright flash of light known as a gamma-ray burst, generated by an exploding massive star when the Universe was only 730 million years old. For the first time for such a remote event, the telescope provided a detection of the supernova’s host galaxy. Webb’s quick-turnaround observations verified data taken by telescopes around the world that had been following the gamma-ray burst since its onset, which occurred in mid-March.
