CEERS-93316
- ≈25.7 billion ly (7.9 billion pc)
(present proper distance)[4] - ≈12.6 billion ly (3.9 billion pc)
(light-travel distance)[4]
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]
