GRB 250314A Pull-out (NIRCam image)

The NASA/ESA/CSA James Webb Space Telescope identified the source of a super bright flash of light known as a gamma-ray burst: a supernova that exploded when the universe was only 730 million years old. Webb’s high-resolution near-infrared images also detected the supernova’s host galaxy. Its quick-turn observations verified data taken by other telescopes that followed bright emission from a gamma-ray burst that came onto the scene in mid-March.

[Image description: Webb image shows hundreds of galaxies of all shapes and sizes against the black background of space. Toward the center-left is a large white spiral galaxy that is almost face-on. To the right of this is a large box, which zooms in on an area at top right. Within the box is a faint red dot at the center, with the label GRB 250314A.]
