James Webb Telescope Discovers Oldest Galaxy Ever Observed

JADES-GS-z14-0, formed 290 million years post-Big Bang, is both ancient and exceptionally luminous, challenging existing astronomical theories.

The James Webb Space Telescope identified JADES-GS-z14-0, the oldest-known galaxy, formed 290 million years after the Big Bang.
This galaxy is unexpectedly luminous, indicating it is several hundred million times the mass of the Sun.
Researchers used Webb's Near-Infrared Spectrograph (NIRSpec) to confirm the galaxy's age and redshift of 14.32.
The discovery challenges existing models of galaxy formation in the early universe due to its brightness and size.
Webb's advanced capabilities continue to reveal unprecedented details about the early universe and distant exoplanets.
