CEERS-93316

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]

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.^[4]

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]
