Previous analyses of Titan's atmosphere have revealed the presence of methane and other hydrocarbons; these compounds could rain down on the surface (believed to be made of frozen water) and form lakes of liquid methane and ethane.

先前的分析显示，泰坦的大气含有甲烷和其他碳氢化合物，这些化合物很可能像下雨般落到泰坦地表（一般相信是由结冻的水所构成的），因而形成液态甲烷或乙烷的湖泊。
