I think it would be fun to do some cool tidbits about each planet over the next couple of days since a lot of people seem to be following the current Mars mission that just started. Each day I'll post a few facts about a planet or two and it might stir up some fun intellectual discussions Plus I'll add a gorgeous photograph or two of each. Saturn: Saturn's rings are fairly young, and will likely erode away to the point of the other gas planets' rings. It's rings are a mere 65 feet thick. The day of the week Saturday is named after it. It's calm appearance is a methane haze that hide some of the most violent storms in the solar system. Saturn is the only other planet to have an earth-like hurricane in the meteorological sense; it's on it's south pole. The eye lets scientists see deep within saturn like a tunnel. There is a storm on its north pole that is a nearly geometrically perfect hexigon, and it never moves, it is just an excellent example of raw mathematics in execution. It's been visited five times by human-built spacecraft. The Cassini spacecraft is still in orbit around it, it sent a probe to land on one of it's moons: Titan. Check out a beautiful photograph of it's intricate rings and shadows with one of its many moons: It has intense auroras: It hosts the only moon in the solar system with an atmosphere. This moon (Titan) is also the only moon to ever be landed on besides our own, here is a picture from its surface. Titan is the size of the planet Mercury and it's surface is nearly identical to earth's minus the volcanism, this is because it has massive lakes of methane that shape it as much as water carves our own. One of the reasons that it was landed on was because it's nearly identical to a primordial earth, but in a frozen state. The reason that water is so important for life is because almost all of the chemical processes that are required for everything requires a bipolar liquid, which is rare, water is one of the only ways for this to happen, the other theoretical possibility for those processes is with liquid nitrogen instead, which appears present in Titans atmosphere. It has been shown that those ingredients + sunlight do produce amino acids. There is an outside chance that life exists there. One of Saturn's smaller moons, only 300km across has water geysers erupting from it. The tidal heating from its orbit around Saturn has the possibility of creating liquid water. These geysers feed one of Saturn's rings. By scientific standards it is the whitest object in the solar system, that is because it is covered in freshly fallen snow which hardens into ice.
