The Potential for Life in Titan's Methane Lakes
Quick fact
Cassini-Huygens discovered Titan's lakes at a chilly -179°C, where methane and ethane exist as liquids—making Titan the only place in our solar system with stable surface liquids besides Earth.
Why this is interesting
We usually look for life by following the water, but what if life thrives in liquid methane? On Saturn's moon Titan, lakes of methane and ethane spark one of the most tantalizing questions in astrobiology.
