The Latest From NASA: James Webb Captures an Explosion That Surprised Scientists

The James Webb Space Telescope just caught a supernova from 12.6 billion years ago, only days after the star exploded. It was hotter and brighter than the nearby supernovae astronomers compared it to. In this video, we explain what Webb found, why scientists are surprised, and what it could tell us about the first stars in the early universe. In this video, you'll learn: What a supernova is, explained in plain English How redshift and infrared light let Webb see back in time How Webb found the new explosion, AT 2026abck, with a "spot the difference" survey The three leading explanations for why it is so hot Why the finding is still unproven and what the missing spectrum could reveal How this fits with NASA's other recent Webb discoveries, including the record seven-hour gamma-ray burst, the dusty star in NGC 1637, and the farthest fast radio burst Note: The AT 2026abck finding comes from a research preprint posted on arXiv on September 29, 2026. It has not been peer reviewed, and it is not a NASA press release. The other discoveries covered come from NASA releases. Sources: NASA Science, arXiv (Zhuang et al., 2026), Daily Galaxy.
