Uranus and neptune (and jupiter!) have small rings. Not anywhere near Saturn and quite hard to visualize (unless you're a giant space telescope shooting in IR, apparently.)
It is now hypothesized that Earth once had rings too.
Saturn itself appears extremely dark at this infrared wavelength observed by the telescope, as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright, leading to the unusual appearance of Saturn in the Webb image.
It's crazy to think of how far that is away on a human scale yet on a cosmological scale it's basically our next door neighbor.
More like in the same room with its face against you. This is 380 ly away and the observable universe is 93 billion ly across. If the observable universe was the diameter of the earth, this image comes from 52 mm away.

I always love Cosmological frames of reference.

When I look at this I could imagine a large brow ridge in the top right corner and a darker area below where an eye should be, then 2 red hands clapping in front of the left side of the face. Clearly there is a god going around making stars, we can see them in this photo.

Ya, well, I see the Care Bears, so it could be them too.
Webb Detects Water Vapor in Rocky Planet-forming Zone
Water, water, everywhere – not in drops, but as steam. Scientists using NASA’s James Webb Space Telescope have discovered that thirsty planets in the PDS 70 system have access to a reservoir of water. Importantly, the water vapor was found within 100 million miles of the star – the region where terrestrial planets like Earth may be forming. (The Earth orbits 93 million miles from our Sun.)
PDS 70 is cooler than our Sun, and is estimated to be 5.4 million years old. It is home to two known gas giant planets, at least one of which is still accreting material and growing. This is the first detection of water in the terrestrial region of a disk already known to host two or more protoplanets.
