JADES-GS-z14-0: A New Farthest Object
Model: gpt-4.1
Prompt version: 1.0
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 its present age.
Practically all of the objects in the featured photograph are galaxies.
