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.
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 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 ]
[3] Significantly, the redshift that was initially reported was photometric (z = 16.4) and would have made CEERS-93316 the earliest and most distant known galaxy observed. [ 1 ] [ 6 ] [ 7 ] [ 8 ] CEERS-93316 has a light-travel distance ( lookback time ) of 12.6 billion years, and, due to the expansion of the universe , a present proper distance ...
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.
