NASA | Propileno em Titã

Synopsis: With a thick atmosphere, clouds, rain and a cycle of giant lakes, Saturn's largest moon Titan is surprisingly Earthlike place. But, unlike the Earth, the moon's surface is too cold for liquid water - instead, clouds, rain, and lakes Titan consist of liquid hydrocarbons such as methane and ethane (which exist as gases on earth).
