CEERS-93316 is a high-redshift galaxy with a spectroscopic redshift z=4.9. [1] 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.[2][3][4][5]

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 of 25.7 billion light-years.[6]

Discovery

The candidate high-redshift galaxy CEERS-93316 (RA:14:19:39.48 DEC:+52:56:34.92), in the Boötes constellation,[2][7] was discovered by the CEERS imaging observing program using the Near Infrared Camera of the James Webb Space Telescope (JWST) in July 2022.[2][3][4][5] 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.[4][5][8]
