    The Webb telescope used gravitational lensing to observe small faint
    galaxies over 13 billion light years away. The claim is that the first galaxies to form were smaller and would be too faint to see, but a
    naturral gravitational lens lines up with a galaxy that might have
    formed around 800 million years after the Big Bang.

    The small "galaxy" may only contain 3,300 solar masses, so it is more
    like what we would call a star cluster. I recall that the star cluster
    that contained SN1987 had around 3,000 stars in it, and it was a group
    of stars on the edge of our Milky Way galaxy.

    Supposedly there are some parts of the universe that are so far away and accelerating away from us due to the expansion of the universe that
    their light will never reach us, so we can't observe that far back into
    the creation of the universe.
