CEERS-93316
Possibly one of the oldest galaxies observed
From Wikipedia, the free encyclopedia
CEERS-93316 is a high-redshift galaxy with a spectroscopic redshift z=4.9. [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]

Discovery
The candidate high-redshift galaxy CEERS-93316 (RA:14:19:39.48 DEC:+52:56:34.92), in the Boötes constellation,[1][2] was discovered by the CEERS imaging observing program using the Near Infrared Camera of the James Webb Space Telescope (JWST) in July 2022.[1][6][7][8] CEERS stands for "Cosmic Evolution Early Release Science Survey", and is a deep- and wide-field sky survey program developed specifically for JWST image studies, and is conducted by the CEERS Collaboration.[7][8][9]
