Saturn’s Mysterious Moons, as well as other phenomenal data about our gas giants and what’s in their orbits, all gathered from Voyager 1, Voyager 2 and Cassini. This video is eighteen-plus minutes of seriously fascinating information.
The two Voyagers sent back tens of thousands of images… of planetary realms more diverse than anyone had imagined. These long-distance marathon flyers – both now headed out towards interstellar space – made discoveries about the planetary chemistry that make these gas giants appear to us as gigantic works of abstract art.
The Voyagers disclosed new details about their magnetic fields, atmospheres, ring systems, and even the nature of their inner cores. Voyager turned up some surprising new mysteries too: a huge dark spot — a storm in fact – on Neptune. They found that Uranus is tipped 90 degrees to one side. That Saturn is less dense than water; if you had a bathtub big enough, Saturn would float!
And that you’d need the mass of three Saturns to make just one Jupiter! But what really knocked the scientists’ socks off were the moons that orbit these gas giants. All of them have been pummeled over the millennia by wayward asteroids and comets.
But a few appear to also be sculpted by forces below their icy surfaces…
