“To our surprise, our model worked remarkably well and the observed supernova seems to match really well the death of stars that we see regularly.”

The James Webb Space Telescope identified the most distant supernova ever observed, an explosion that occurred when the universe was only 730 million years old. Initially detected as a gamma-ray burst in March 2025, infrared observations confirmed it 110 days later. The surprising finding: this ancient stellar death looks nearly identical to supernovae in the nearby universe, suggesting early stars died much the same way as modern ones.
