Hubble is the result of a major screw up by Perkin Elmer.
They ground the primary mirror to the wrong figure because they got the millimeter-inch thingie wrong. Only cost a few hundred million dollars.
There’s been some dynamic atmospheres coming out of Uranus for a long time now.
Especially after tacos and beers night!!
Still waiting on your facts. Here’s mine. When it was first launched, it couldn’t see shit. They put another lens on it and it can see objects that no ground telescope can see 100 billiion light years away. Yeah I buy it.
“OK, so no referrals to the violent collision that knocked Uranus off its axis?”
Uranus has not been knocked off its axis. Uranal warming is causing the polar ice cap to slide further down the planets surface as it melts. We need to take drastic action before it reaches the bottom of Uranus.

That's not a fact, it's a falsehood. Even before the corrector was installed, Hubble was returning better images than terrestrial telescopes. Just not as much better as they should have been.
You're in a position to learn on this forum if you'll let yourself.
Stuff inside this solar system is way to close to focus clearly.
Because of the camera angle. Sorry, couldn’t find a diagram for Uranus, but this shows Venus and Mercury, you’ll get the idea:

You might want to look up the term “focal length”. The moon is too close.
The argument you are using smells suspiciously like flat earth garbage.
So if that’s the case, and it can see nearer objects like Jupiter clearly, why can’t it see objects a bit further away like Neptune but can clearly see objects at light years distant?
not buying the whole “oh its bigger (or closer) so that’s why it clearer” argument.
Neptune gets much, much less light from the sun than Jupiter, due to the inverse square law - approximately 3% of the brightness of the sun at Jupiter, and the light is dimmed about 30 times more coming back to Earth, for a total effect of Neptune appearing 1000 times dimmer than Jupiter when viewed from Earth (not even counting the smaller size of Neptune.
The Hubble can attempt to compensate by making a longer exposure, but that will cause blurring due to Neptune’s rotation.
It is no surprise that Neptune appears nearly featureless in photos from Hubble.
Remember when they first put it up? It couldn’t see at all.
True, Uranus was a bit boring, but not the moons, especially Miranda.
