Scientists have found that Saturn’s largest moon Titan has small liquid lakes that run more than 100 metres deep, perched atop hills and filled with methane.

• Scientists suspect the lakes were formed when surrounding bedrock chemically dissolved and collapsed a process which occurs with a certain type of lake on Earth.
• The scientists also observed “phantom lakes” on Titan that during wintertime appeared to be wide but shallow.
• Evidence about Titan’s hydrological cycle, with liquid hydrocarbons raining down from clouds, flowing across its surface and evaporating back into the sky which is comparable to Earth’s water cycle.
• Scientists suspect Titan could potentially could harbour life possibly in the surface bodies of liquid hydrocarbons because of Titan’s complex chemistry and distinctive environments.

Titan is the most Earth-like body in the solar system. It has lakes, canyons, rivers, dune fields of organic sand particles about the same size as silica sand grains on Earth.
