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.
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]
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.
Also based on oxygen-related measurements, the age of the galaxy is confirmed. [11] [12] GLASS-z12 derives its name from the GLASS survey that discovered it and its estimated photometric redshift of approximately z = 12.4 +0.1 −0.3. [1] GLASS-z12 was initially announced as GLASS-z13 because it was thought to have a higher redshift of z = 13.1.
The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant , or faint for the Hubble Space Telescope . [ 9 ]

Like our home galaxy, the newly discovered ceers-2112 is a barred spiral galaxy, and it’s now the most distant of its kind ever observed. The bar at the center of the structure is made of stars.
