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.
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).
F200DB-045 is a candidate high-redshift galaxy, with an estimated redshift of approximately z = 20.4, [2] [3] corresponding to 168 million years after the Big Bang. [4] If confirmed, it would be one of the earliest and most distant known galaxies observed.
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 ...
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.
[8] [9] Spectroscopic observations of GLASS-z12 by the Atacama Large Millimeter Array (ALMA) in August 2022 confirmed that the galaxy has a spectroscopic redshift of 12.117 ± 0.012, making it one of the earliest and most distant galaxies ever discovered, dating back to just 350 million years after the Big Bang, 13.6 billion years ago.
