You'll really be doing yourself a disservice if you don't go here and check out the incredible new high-rez shot of Saturn where you can see all of the cool details. Bad Astronomy runs down some of them:
"Cassini was high above Saturn to the north, looking “down” on the ringed world when it took these images. You can see the bizarre hexagonal north polar vortex, the six-sided jet stream flowing around Saturn. The subtle but beautiful bands mark the cloud tops of Saturn’s atmosphere. Unless I'm mistaken, the thin white line you see wrapping around the planet at mid-latitude is the remnant of a vast storm so huge it completely dwarfed our own home world of Earth. And if you look carefully (you can measure it!) you can see that Saturn is highly flattened, its equatorial diameter wider than through the poles."Click through for lots more. Incredible stuff.
