JADES-GS-z14-0: A New Farthest Object
Explanation: What if we could see back to the beginning of the universe? We could see galaxies forming. But what did galaxies look like back then? These questions took a step forward recently with the release of the analysis of a James Webb Space Telescope (JWST) image that included the most distant object yet discovered. Most galaxies formed at about 3 billion years after the Big Bang , but some formed earlier. Pictured in the inset box is JADES - GS-z14-0 , a faint smudge of a galaxy that formed only 300 million years after the universe started . In technical terms, this galaxy lies at the record redshift of z=14.32, and so existed when the universe was only one fiftieth of the its present age. Practically all of the objects in the featured photograph are galaxies.
