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]
[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.
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 since becoming operational in 2022 has uncovered numerous surprises about what things were like in the universe's early stages. Scientists said on Wednesday that ...
[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 ...
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 ...
Data captured via energetic X-rays by the Chandra X-ray Observatory and James Webb Space Telescope has helped astronomers spot the signature of a growing black hole within the early universe just ...
