Hello,
excuse my extended absence on the blog. Today we will talk about Titan, a moon of Saturn. And 'the second satellite el of the solar system 'with a unique' atmosphere.
Titan is a world cold and dark, on the outskirts of our solar system, constantly covered by clouds. It is estimated that 90% of the sunlight is blocked from them. But clouds of what? This is ethane and methane, which in this cold moon behave like the 'water on Earth. On the surface, composed of ice 's water and rocks, there are rivers and lakes of methane / ethane. The temperatures on Titan are close to the triple point of methane, methane can exist where liquid, solid and gas. It is not water, but it is a liquid, and the extremophile bacteria could thrive even at -180 ° C. But if the surface is extraordinary, in the subsoil the planet could exist an ocean of liquid water that kept the pressure bodies where even more similar to terrestrial bacteria.
Titan might hold of the continents, ice sheets that move above the 'water.
