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.
NASA's Webb Telescope Finds Record-Breaking Oldest Supernova Ever Recorded
A faint, ancient flash of light detected by the James Webb Space Telescope (JWST) has broken the record for the most distant stellar explosion ever recorded, revealing a massive star’s demise when the cosmos was just a child. Astronomers confirmed the event occurred approximately 13 billion years ago (versus the Big Bang at 13.8 billion years
