Later images may be the result of more recent advances in image processing filters applied.
I'm sure the scientists are adjusting the flow to get the most striking results.
As always you can go back and pull the raw data and check the tags to see how the image collection and processing changed.

Because JWST "sees" using different wavelengths, it images dust differently. Dust that can be seen in the Hubble photo may be too small to be seen by the longer wavelength used by JWST.
If you put them side by side, you will see patches of dust that are not there in the newer photos.

Once again, the speed of light is a constant to all observers. That makes it a terrible yardstick, because different observers see different things.
As an earth based human I see the big bang coming from all directions because it was 14 billion years ago in every direction! I know the mass of the universe is contained within that still expanding sphere.
I also know that every other observer (who uses light) from their planet will also see a perfect sphere around their own planet. This is a fundamental flaw in light years as a yardstick.
Calculations for other observers may show other things but in the universe I see, two galaxies in opposite directions from earth can be at most twice the age of the universe apart. Note: that number is climbing at 2*C.
And the part that hurts my brain is that each of those two ultimate polar opposite galaxies will also see the CMB as a sphere around them.

But the photons from the big bang boundary have been traveling at the speed of light for 14 billion years and are arriving here today. The CMB comes from a perfect sphere around us, visible in every direction, with all the matter in the universe inside that sphere. We see the entire sphere of CMB and yet fools talk about the unobservable parts of the universe.

But the CMB photons are from the big bang itself. And they have been traveling ~14billion years.
If your yardstick changes size you can make any numbers you want come out.

Nothing CAN go faster than light. Take a yardstick, put a hinge at one end and a piece of paper on the table at the other end. Calculate the angular velocity as you slam it to the table. Measure the thickness of paper. Identify the intersection of top of paper (horizontal) and bottom of yardstick (hinged at far end) and derive the velocity of the intersection point at max angular velocity. You will find that for thin enough paper, that point, though not a physical object, is moving faster than C.
So Nothing, can go faster than light.

The universe is expanding at the speed of light on all sides. We can see the CMB in every direction and the source is receding at C!
To reach the edge of the universe is impossible because that edge is already moving at the fastest speed possible.

Be sure to check recent work! Last year a report on stomach contents of animals killed by the initial event and blast wave revealed what season of the year it happened in.
65 million years ago, a rock fell out of the sky
And turned dinosaurs into birds & mice into men

In a two body universe, objects starting far apart will either collide or fall into an oval orbit retaining the original distance as the major axis.
For a planet to capture a wandering moon, as your question might mean, it takes help. If the original vectors are helpful, and the time sequence imposes the right acceleration, the moon wandering past can be permanently captured. Orbit might not be circular at first, but yes, it is possible.
