GN-z11 is a high-redshift galaxy found in the constellation Ursa Major.It is among the farthest known galaxies from Earth ever discovered. [5] [6] The 2015 discovery was published in a 2016 paper headed by Pascal Oesch and Gabriel Brammer (Cosmic Dawn Center).
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.
[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.
While scientists have found similar “dead” galaxies before, it is the oldest by 500 million years. Scientists say the galaxy lived fast and died young, the Cambridge researchers who found it said.
These were the most remote objects discovered at the time. The pair of galaxies were found lensed by galaxy cluster CL1358+62 (z = 0.33). This was the first time since 1964 that something other than a quasar held the record for being the most distant object in the universe.

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 ...
Two powerful NASA telescopes have detected the oldest and most distant black hole ever found. ... the galaxy appeared in the same direction as a cluster of galaxies known as Abell 2744, which is ...
JADES-GS-z7-01-QU (also known as JADES-GS+53.15508-27.80178) [1] is a Lyman-break galaxy, first identified in 2010, [2] located in the constellation Fornax.It formed around 700 million years after the birth of the universe, after which it suddenly stopped creating new stars. [3]
