Airs Tuesdays at 9pm/8c on HISTORY. They are breathtaking, lethal and a constant source of surprise. The stunning rings of Saturn have mesmerized countless scientists over the centuries.

Inside the rings is like a NASCAR race--with bumping, jostling and frequent collisions that can cause a massive spin-out.
