Titan is an intriguing world – in a way quite similar to Earth. In fact, it is the only moon of the Solar System with a substantial atmosphere and the only celestial body other than our planet where stable bodies of surface liquid are known to still exist.

In this unique methane cycle, the hydrocarbon molecules evaporate, condense into clouds and rain back onto the ground.
