US EditionThe James Webb Space Telescope Just Found the Oldest Supernova Ever Seen
The James Webb Space Telescope captured the most distant supernova ever, dating 13 billion years back, with a redshift of 7.3, a rare event observed by multiple international observatories.
- On July 1, the James Webb Space Telescope used its Near-Infrared Camera to detect light from the 13-billion-year-old supernova, marking the most distant supernova recorded at 730 million years after the Big Bang.
- SVOM triggered the alert on March 14, then Swift and ground telescopes moved quickly to locate and follow the burst, with the Nordic Optical Telescope detecting an afterglow 11 hours later.
- The Very Large Telescope confirmed a redshift of 7.3 for the afterglow, and researchers report the supernova's spectrum resembles modern explosions while Webb detected the host galaxy.
- Co-Author Andrew Levan's team secured Director's discretionary time on JWST and published results in December in Astronomy & Astrophysics, gaining additional Webb observing time for early-Universe GRBs.
- `We went in with open minds` co-author Nial Tanvir said, noting early stars had fewer heavy elements and researchers need more data to analyze the supernova's spectrum with future Webb observations.

The James Webb Space Telescope just found the oldest supernova ever seen
The James Webb Space Telescope detected the oldest supernova on record. It was seen accompanied by a gamma-ray burst, signaling the core collapse of a massive star and the probable birth of a black hole.
European scientists have managed to detect the oldest supernova ever, which occurred when the entire universe was only 730 million years old.
The light of the oldest supernova explosion ever observed, 13 billion years old and dating back just 730 million years after the Big Bang, was recorded by the James Webb Space Telescope… The James Webb Space Telescope detected the oldest supernova explosion in the Universe - ΙΝΑΦΤΕΜΟΠΟΡΙΚΙ
NASA’s Webb Identifies Earliest Supernova to Date, Shows Host Galaxy
NASA’s James Webb Space Telescope has observed a supernova that exploded when the universe was only 730 million years old — the earliest detection of its kind to date. Webb’s crisp near-infrared images also allowed astronomers to locate the supernova’s faint host galaxy. The telescope took these…
