Ever wonder how the heck Saturn got to have such enormous, perfectly flat rings? In this cool video from Universe Today's Fraser Cain, you'll discover that astronomers are wondering the same thing. In fact, it's a huge debate.

Scientists like Kevin Grazier, who worked on NASA's Cassini probe to Saturn, are stumped by the rings. Are they new or old? How do they remain in such a perfect shape, rather than plunging into Saturn's gravity well and burning up in the gas giant's atmosphere? Watch this terrific video to find out what the latest theories are.

Also watch just to see Cain standing in the beautiful, snowy wilds of an island off the coast of British Columbia.
