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.
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.
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.

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).
The newly discovered galaxy, named JADES-GS-z7-01-QU, existed about 700 million years after the big bang, until something made star formation suddenly stop.
Astronomers detected the black hole in a galaxy called UHZ1. At first glance, the galaxy appeared in the same direction as a cluster of galaxies known as Abell 2744, which is located about 3.5 ...
The James Webb Space Telescope has four key goals: to search for light from the first stars and galaxies that formed in the universe after the Big Bang; to study galaxy formation and evolution; to understand star formation and planet formation; to study planetary systems and the origins of life [160]
