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.
