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).
It was discovered alongside another galaxy, GLASS-z10, comparable to GN-z11, also one of the oldest galaxies discovered. [10] Color composite of JWST-NIRCam images showing GLASS-z12 as a red dot among other galaxies
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.
The James Webb Space Telescope keeps finding galaxies that shouldn’t exist, a scientist has warned.. Six of the earliest and most massive galaxies that Nasa’s breakthrough telescope has seen ...
Two NASA telescopes discovered the oldest known black hole, which formed just 470 million years after the big bang created the universe.
JADES-GS-z14-0 is a high-redshift Lyman-Break galaxy in the constellation Fornax that was discovered in 2024 using NIRcam as part of the JWST Advanced Deep Extragalactic Survey (JADES) program. [1] [2] It has a redshift of 14.32, making it the most distant galaxy and astronomical object ever discovered.
