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.
