WHL0137-LS, also known as Earendel, is a star cluster or a star located in the constellation of Cetus. Discovered in 2022 with the Hubble Space Telescope, it has a comoving distance of 28 billion light-years (8.6 billion parsecs), making it the most distant known star if it is a single object. The previous farthest known star, MACS J1149 Lensed Star 1, also known as Icarus, at a comoving distance of , was discovered by Hubble in 2018. However, further observations from the James Webb Space Telescope (JWST) in the 2020s revealed that Earendel is more likely a star cluster. Objects like Earendel

HD1 is a proposed high-redshift galaxy, which is considered (as of April 2022) to be one of the earliest and most distant known galaxies yet identified in the observable universe. The galaxy, with an estimated redshift of approximately z = 13.27, is seen as it was about 324 million years after the Big Bang, which was according to scientists around 13.787 billion years ago.

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 at the time, with a light-travel distance (lookback time) of 13.4 billion years. Because of the expansion of the universe, its present proper distance is approximately 33 billio
