JWST Discovers Most Distant Galaxy, Redefining Cosmic History

The James Webb Space Telescope has identified JADES-GS-z14-0, a galaxy dating back 285 million years after the Big Bang, setting a new record for the farthest galaxy observed.

JADES-GS-z14-0 is the most distant galaxy ever confirmed, located 285 million years post-Big Bang.
The discovery was made using JWST's NIRCam and NIRSpec instruments as part of the JADES program.
This galaxy is unexpectedly bright and spans about 1,700 light-years, challenging existing theories.
Spectroscopic analysis was crucial in distinguishing JADES-GS-z14-0 from a closer galaxy along the same sightline.
The finding extends our understanding of the early universe by 40%, showcasing JWST's unprecedented capabilities.
