Spectroscopic observations by JWST's NIRSpec instrument in October 2022 confirmed the galaxy's redshift of z = 13.2 to a high accuracy, establishing it as the oldest and most distant spectroscopically-confirmed galaxy at the time, with a light-travel distance (lookback time) of 13.4 billion years.
The James Webb Space Telescope (JWST) is an international 21st-century space observatory that was launched on 25 December 2021. [1] [2] It is intended to be the premier observatory of the 2020s, combining the largest mirror yet on a near-infrared space telescope with a suite of technologically advanced instruments from around the world.

Also based on oxygen-related measurements, the age of the galaxy is confirmed. [11] [12] GLASS-z12 derives its name from the GLASS survey that discovered it and its estimated photometric redshift of approximately z = 12.4 +0.1 −0.3. [1] GLASS-z12 was initially announced as GLASS-z13 because it was thought to have a higher redshift of z = 13.1.
2022 – James Webb Space Telescope (JWST) releases the Webb's First Deep Field. 2022 – JWST detects CEERS-93316, a candidate high-redshift galaxy, with an estimated redshift of approximately z = 16.7, corresponding to 235.8 million years [44] after the Big Bang. [45] If confirmed, it is one of the earliest and most distant known galaxies ...
Scientists said on Wednesday that Webb has spotted a galaxy where star formation had already ceased by roughly 13.1 billion years ago, 700 million years after the Big Bang event that gave rise to ...
The James Webb Space Telescope has revealed a galaxy far, far away, from back when our universe was an infant. This Could Be the Oldest Galaxy We’ve Ever Laid Eyes On, Thanks to Webb Skip to ...
Since the beginning of the James Webb Space Telescope's (JWST) science operations in June 2022, numerous distant galaxies far beyond what could be seen by the Hubble Space Telescope (z = 11) have been discovered thanks to the JWST's capability of seeing far into the infrared.
Ceers-2112 formed soon after the big bang created the universe (which is estimated to be 13.8 billion years old), and the galaxy’s distinct structure was already in place 2.1 billion years later.
