Saturn's storms may be smaller than Jupiter's, and its core temperatures cooler, but its rings far surpass Jupiter's in size and splendor.
They're a quarter of a million kilometers wide, but only one and a half kilometers thick. They're made of water ice and ice-covered rock, and may be the remains of moons or asteroids smashed to pieces by Saturn's gravity.
Voyager flew by Saturn's large moon titan, whose nitrogen atmosphere is tinged reddish-brown with methane and what may be organic molecules... but for Voyager this smog obscured the ocean some think may lie below.
Voyager 2 used Saturn's gravity to slingshot it on to Uranus, a planet that's mostly water, ammonia and methane.
This planet's pole points to the Sun, which may be the result of some vast cosmic collision in the past.
