Seti.org Article ("Uranus Has a Dark Spot"):
During the past decade, many bright spots have been seen on Uranus, in both red and near-infrared filters. But this is the first dark spot ever seen on the planet.
Thanks to Digg user "chris9902" for providing the following joke:
Farnsworth: Go ahead, try it. You'll find that every heavenly body has its own particular scent. Here, I'll point it at Jupiter.
Fry: Smells like strawberries.
Farnsworth: Exactly! And now Saturn.
Fry: Pine needles. Oh, man, this is great! Hey, as long as you don't make me smell Uranus! (Laughs nerdily)
Leela: I don't get it.
Farnsworth: I'm sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all.
Fry: Oh. What's it called now?
Farnsworth: Urectum.
