Question

Does life exist in Titan?

Answer 1

Titan is the second-largest moon in our solar system. Titan is bigger than Earth’s moon and larger than even the planet Mercury. Titan’s atmosphere is primarily nitrogen, plus a small amount of methane. It is the sole place in the solar system known to have an earth-like cycle of liquids raining from clouds, flowing across its surface, filling lakes and seas, and evaporating back into the sky (akin to Earth’s water cycle).

• It has been speculated that life could exist in the liquid methane and ethane that form rivers and lakes on Titan’s surface, just as organisms on Earth live in water.
• Titan is not a pleasant place for life. It is far too cold for liquid water to exist, and all known forms of life need liquid water.
