Agreed! In the SMACS 0723 image, there is a red spiral galaxy near the top right which is effectively not present in the HST image because it was redshifted out of the spectrum. This implies it's one of the galaxies receding the fastest from us in the image right? And therefore also among the oldest and farthest away?

The reddest objects in the JWST are frequently not even present in the Hubble image, as they were redshifted into a band of light Hubble couldn't even detect. That's my favorite part about this image - those galaxies we can now see which were previously redshifted beyond our capacity to detect. They're the oldest, and receding from us the fastest.
