The JADES-Gs-z14-0 and JADES-Gs-z14-1 galaxies as seen by the James Webb Space Telescope, also zoomed in the insets

An article still in its peer-reviewed phase available in preview on the ArXiv server reports the identification of the primordial galaxies JADES-GS-z14-0 and JADES-GS-z14-1, which might be the most distant galaxies discovered so far. A team of researchers used observations conducted with the James Webb Space Telescope as part of the JWST Advanced Deep Extragalactic Survey (JADES) program to identify hundreds of candidate galaxies dating back to the first 650 million years of universe life. If the estimates made are confirmed, we see JADES-GS-z14-0 as it was about 290 million years after the Big Bang and therefore it would be the oldest known.
