Space.com reported, "These two galaxies, magnified by a gravitational lens, have properties that support the basic picture of galaxy formation as described in the Big Bang theory...Wang and her team were able to identify the lensed images of two high-redshift galaxies. One, designated UNCOVER-z13 ("z" is shorthand for "redshift"), has a redshift of 13.079, confirming it to be the second most distant galaxy known...The other galaxy recently discovered, UNCOVER-z12, has a redshift of 12.393, placing it in fourth place in the all-time list of most distant galaxies. We see this realm as it was just 350 million years after the Big Bang...What marks the two UNCOVER galaxies out as different is their appearance. Other galaxies seen at similarly high redshifts seem to be point-like, indicating they are very small — just a few hundreds of light years across. The UNCOVER galaxies, on the other hand, have structure. "Previously discovered galaxies at these distances … appear as a dot in our images," Wang said in a statement. "But one of ours appears elongated, almost like a peanut, and the other looks like a fluffy ball." These galaxies are also bigger, with UNCOVER-z12 sporting an edge-on disk about 2,000 light years across, which is six times larger than other galaxies seen in this era…Although the dichotomy in galaxy properties, even at this early stage in the universe, is eye-opening, both of the newfound realms have general characteristics that are strongly supportive of the Big Bang model…"
My observation, cosmology calculators (example,
https://lambda.gsfc.nasa.gov/toolbox/calculators.html, and
https://www.kempner.net/cosmic.php) show the angular size distance. It does appear that problems exist for the BB cosmology concerning high redshift galaxy sizes and the one arcsecond map size to redshift number as well as comoving radial distances where space expands much faster than c velocity today. At the comoving radial distances, the large red shift galaxies cannot be observed and measured, thus any cosmic evolution using those distances is not verifiable. JWST does not see the pristine, primordial gas clouds said to exist in the early universe created during BBN, only metal poor but no metal free gas clouds and no Population III stars confirmed.
