Titan's lakes, by the way, aren't your usual bodies of water — instead, they're filled with liquid methane and ethane.

顺带一提，泰坦湖泊里的液体并不是通常意义上的水，而是液态的甲烷和乙烷。

Even though Titan lacks sunlight, NASA's Huygens probe detected what looked like liquid methane on the mini planet's surface in 2005.

虽然泰坦上缺少阳光，NASA的惠更斯号探测器于2005年在这颗微型星球表面探测到一些类似液态甲烷的物质。

The ice remains covered up even as liquid methane and ethane flow all over Titan's surface and fill up lakes and seas much as liquid water does on Earth.

也许它的冰冷表面覆盖着液态甲烷和液态乙烷，它们会积聚成湖泊甚至大海，就像地球上由水形成的江河湖海一样。

Apart from burning more smoothly, and inflicting lower stresses on delicate satellites, liquid methane costs only 1% as much as liquid hydrogen.

According to a new computer model, liquid methane in contact with a partially hydrogen-terminated diamond surface at extremely high pressures and temperatures spontaneously forms longer hydrocarbons, and hence the material of crude oil could be formed deep in the earth.

This prompted suggestions in the 1980s that Titan could be entirely covered by a liquid-methane ocean.
