Saturn's rings have been mystifying experts and amateurs alike since Galileo first observed them in 1610. It wasn't until 1659 that Dutch astronomer Christiaan Huygens identified them as rings (Galileo thought they might have been "ears," or two moons). More than two hundred years would pass before NASA's Pioneer 11 probe gave us our first close-up view in 1979.

Saturn's rings were well-known by the time Pioneer reached the far-off planet, but the gas giant was hiding another feature that wasn't uncovered until Voyager returned at the beginning of the '80s — an enormous hexagonal storm, unlike anything seen on Earth. SPACE.com cites NASA figures in stating that the storm is 20,000 miles across, with winds rushing along at speeds up to 200 miles per hour!

Check out the epic footage below, and be sure to let us know: which do you think is more impressive — the rings or the storm? Join the conversation in the comments, and as always, remember to share it with your friends on Facebook!
