Well, generally the most important thing we learned is how diverse the bodies of the solar system are. Each one is unique and that's because they've had a different history, different evolution. Jupiter, with it's great red spot is just the largest of dozens of giant hurricane-like storm systems. And two of Jupiter's moons, Io, has a 100 times more volcanic activity than Earth. Europa has an ice crust probably on the liquid water ocean. On to Saturn, we've found Saturn's rings are riddled with wakes from moons, which are orbiting inside the rings and outside the rings. And there is a moon there called Enceladus, which is the whitest, brightest object in the solar system and has a very fresh surface. And there's the moon Titan, which has an atmosphere in which liquid natural gas rains on the surface.
