Titanomachia

Titan (and Mimas - the Death Star moon)! Second biggest moon in the Solar System, and maybe first in our hearts (tough choices). It is one of two moons with an atmosphere, and a very thick one at that. Nitrogen based, like Earth's. However, Earth has no views like this:

An excellent art piece as well. For reference, Titan is bigger than Mercury, and far more interesting, though that's an opinion I suppose. What Titan tells us - and all the other cool moons, but especially Titan - is that moons can be quite diverse, and that large planets can have quite many of them, acting like mini "solar" systems. Saturn to date has a confirmed 62 moons, with more likely to come. More art:

I can't tell you all their names correctly, except Titan at center, occulted. Each moon can exert a gravitational influence on the other moons, and I'm sure one day we'll discover a moon with a moon. It will be cool. For now, appreciate Titan:

More false color. "False color" means scientists have assigned colors to the image based on the data at hand. It's accurate for what it is, but also subjective to a degree, though also close enough. For the record, just about any cool color space shot you've seen is false color to some degree. Here's the real deal:

More lakes! The fishin' ain't so good though, one assumes. As the liquid on Titan is methane, and the mountains and valleys and boulders and rocks are ice. Wicked hard ice - the temp on the surface is around -200 degrees Celsius. Cold as heck. It is truly an alien world, but oh so familiar:

Titan seas, with islands. One day our robot children will vacation on the shores of Methane Sea.

Rivers of methane emptying into methane seas. It's like Earth, but will never be like Earth. Titan is highly inhospitable to us, and so it will be left to the robots. Check out this amazing pic:

The surface of Titan, as seen by Huygens - a probe shot from Cassini during its early years. Another feather in the cap of this amazing science mission. Those are little pebbles of ice. Rounded from some type of erosion, be it liquid or wind. Titan has all the weather we have on Earth, except it's methane raining down from the orange clouds. So cool.

Is there life? Seems hard to imagine, but every year we find life on Earth in the strangest of places - super heated volcanic vents at the bottom of the ocean; 6 miles below ground deep in the bedrock; way, way high in the sky, floating bacteria living forever in the clouds. Life is everywhere on Earth, and it seems it has always been so - evidence of life now goes back to just a few hundred million years after the creation of Earth as we know it - which is not the original Earth, not by many iterations.

Perhaps some form of life similar to life on Earth exists on Titan. Or perhaps a life unlike life on Earth exists on Titan. Or, more likely, life does not exist on Titan, at least not on the surface. It is possible Titan has a vast underground ocean of warm liquid water, and imagine what kind of sealife might evolve there. Gnarly stuff, like everything in the ocean. One day we'll find out - we need to send out the bots in our name.
