Titan: big, windy, and not at all solid
Let’s not beat around the bush here: Cassini just discovered that Titan — one of the moons of Saturn — is very likely to have an underground ocean. This is a major find, since one of the things we already know about Titan is that it’s littered with organic compounds. I think we all know what happens when you have organic compounds and liquid water in proximity to one another.
Though, as Phil Plait wisely cautions us, it’s too early to say anything with certainty. It’s always possible that it’s actually an ocean of mercury or some terrible thing like fluorine, or any number of equally non-life-supporting options. But it sure looks promising right now.
