James Webb Space Telescope 'pushed to its limits' to see most distant galaxies ever
Prior to this discovery, made as part of the James Webb Space Telescope's (JWST's) Galactic Legacy Infrared Midplane Survey Extraordinaire (GLIMPSE) project, the most distant galaxy observed by the powerful space telescope was JADES-GS-z14-0. That one was seen as it was when the universe was around 280 million years old.
