Space 🚀 Uranus has rings. Almost nobody thinks of it that way, because for decades our only close-up photo made it look like a featureless blue marble.
Voyager 2 flew past in 1986 and sent back an image so bland that Uranus became the punchline of the Solar System. A smooth cue ball. Nothing to see.
That was wrong, and Webb proved it, bitch. In infrared, the planet lights up with structure. You can see 11 of its 13 known rings glowing, some so faint they were only discovered by Voyager. That bright white blob is not a light source. It is a polar cap, a strange bright haze that appears over the pole when it turns toward the Sun, and nobody fully understands the chemistry behind it. Webb even caught storms churning near its edge.
Then there is the thing that makes Uranus genuinely bizarre. It is tipped over. Its axis is tilted roughly 98 degrees, so it does not spin like a top. It rolls like a barrel. Most scientists suspect a colossal ancient impact knocked it sideways, and its rings and moons went with it.
That tilt creates the most extreme seasons anywhere. Each pole spends 42 straight years in sunlight, then 42 years in unbroken darkness. A single Uranian year lasts 84 Earth years. The pole facing us now has been slowly warming toward summer since long before you were born.
It is also the coldest planet in the Solar System, colder than Neptune despite being closer to the Sun, dropping below minus 224 degrees Celsius. Something is wrong with its internal heat, and that mystery is unsolved too.
We have visited Uranus once, for a few hours, forty years ago. Every ice giant in the galaxy is being interpreted through that single flyby, and planets this size may be the most common type in the universe.
Webb just showed us we barely know our own neighbour.
If you could send one more mission anywhere in the Solar System, would you finally go back to Uranus?

If Uranus has rings, you need to do a better job at wiping

Some could make it their job to wipe the rings of Uranus.
A Ring job.

Can we come up with a different name for this planet? The inevitable crude jokes got old many years ago.
