JADES-GS-z13-0 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST) during NIRCam imaging for the JWST Advanced Deep Extragalactic Survey (JADES) on 29 September 2022. 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 known as of 2023, with a light-travel distance (lookback time) of 13.4 billion years.[4][3] Due to the expansion of the universe, its present proper distance is 33.6 billion light-years.[2]

JADES-GS-z13-0 is located in the Great Observatories Origins Deep Survey – South (GOODS-S) field in the constellation Fornax, which includes the Hubble Ultra Deep Field.[1][5]

A paper in April 2023 suggests that JADES-GS-z13-0 isn't in fact a galaxy, but a dark star with a mass of around a million times that of the Sun.[6]
