Some additional reports on this interesting, high redshift galaxy and the difficulty fitting into the BB model.

He emphasized that more similar observations would be needed to validate this hypothesis. However, astrophysicist Alfred Tiley noted in a Nature News & Views article accompanying this study, these findings are based off of a single galaxy. "The result provides valuable input for a present-day discussion about how galaxies form," according to a statement from the Max Planck Institute. Researchers suggest that the galaxy might have formed by a process known as "cold-mode accretion." They think that the gas falling in towards the galaxy's center was actually cold so, because the gas didn't need time to cool down as it approached the galactic center, the disk was able to more rapidly condense. doi: 10.3847/1538-4365/acaaa9.An ALMA radio telescope image of the Wolfe Disk, seen when the universe was only ten percent of its current age.

If confirmed, the galaxy may have existed in its star formation phase in the early universe, when it would have been composed mostly of dust as well as young and massive population III stars. Spectroscopy could also determine the chemical composition, size and temperature of the galaxy. Only a photometric redshift has been determined for F200DB-045 follow-up spectroscopic measurements will be required to confirm the redshift (see spectroscopic redshift). This data included a nearby galaxy cluster SMACS J0723.3–7327, a massive cluster known as a possible "cosmic telescope" in amplifying background galaxies, including the F200DB-045 background galaxy. The candidate high-redshift galaxy F200DB-045 was discovered within the data from the Early Release Observations (ERO) that was obtained using the Near Infrared Camera of the James Webb Space Telescope (JWST) in July 2022. Nonetheless, the redshift value of the galaxy presented by the procedure in one study may differ from the values presented in other studies using different procedures. If confirmed, it would be one of the earliest and most distant known galaxies observed.į200DB-045 would have a light-travel distance ( lookback time) of 13.7 billion years, and, due to the expansion of the universe, a present proper distance of 36.1 billion light-years. Possibly one of the oldest galaxies observed F200DB-045į200DB-045 is a candidate high-redshift galaxy, with an estimated redshift of approximately z = 20.4, corresponding to 168 million years after the Big Bang.
