Watching Saturn and Earth from afar, space alien astronomers would note that Earth whips around the Sun nearly 30 times for every one orbit Saturn completes. That's because Earth is 10 times closer to the Sun than Saturn, and hence caught in the Sun's tighter gravitational grasp. Every time Earth "laps" sluggish Saturn, like two NASCAR racers, astronomers aim Hubble at the glamorous world to get a close-up look. Like Earth, Saturn is tilted on its axis and so goes through seasons. In this snapshot it is summer in the northern hemisphere. Hubble's crisp view shows multiple banded cloud activity warmed increasingly by direct sunlight. The spectacular ring system remains as mysterious as it is gorgeous. Astronomers still debate intensely if the rings are a relatively new decoration to the gas giant planet, or if they're as old as the solar system itself.
