Great find, Johnny! Your "other" galaxy is definitely a real spiral galaxy, and it is interacting with a smaller galaxy as well.

Re: APOD: Young Star Cluster NGC 346 (2023 Jan 13)
I wonder if the right core is in fact a red dwarf star at 10 ly distance from us moving fast between the two snapshots.
Does GAIA have it catalogued?

Your "other" galaxy (or galaxies) strengthens my belief that the first object is also a galaxy, in spite of its strange double nucleus. Note how similar the objects are in size, color and morphology. That is exactly what we would expect if these two are galaxies of a similar size, morphology and dust content (or lack thereof), and at a similar distance from us.johnnydeep wrote: ↑Sat Jan 14, 2023 8:51 pmYes, it's indubitably a pair of galaxies, unlike the debatable other "one".Ann wrote: ↑Sat Jan 14, 2023 6:21 pmjohnnydeep wrote: ↑Sat Jan 14, 2023 3:26 pm Hey, did anyone notice the OTHER galaxy that looks quite similar to the possibly double nucleated one being discussed above?

Re: APOD: Young Star Cluster NGC 346 (2023 Jan 13)
I wonder have these three stars formed from the same proto-disk and do they remain bound?
The middle one seems to move ↙ from HST to JWST by the way the fourth bright dot (only in JWST) must be a background galaxy

The galaxies look red in the HST image because they were (by far most strongly) detected by HST:s infrared filter.VictorBorun wrote: ↑Sun Jan 15, 2023 12:08 pmbut here HST portraits both cores as redAnn wrote: ↑Sun Jan 15, 2023 5:40 amYour "other" galaxy (or galaxies) strengthens my belief that the first object is also a galaxy, in spite of its strange double nucleus.
