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.
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
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.

UNCOVER-z13 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST) [1] during NIRCam imaging for the JWST Ultradeep NIRSpec and NIRCam Observations before the Epoch of Reionization (UNCOVER) project [2] on November 14, 2023. UNCOVER-z13 is within Abell 2744 supercluster in the constellation Sculptor. [3]
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 ...
