Saturn’s moon Titan is the only other object in the solar system known to have liquid on its surface. However, with temperatures as low as -179°C, these lakes are definitely not filled with water.

Titan’s hydrocarbon lakes are poorly understood, but a NASA-supported project hopes to gain a better understanding of their properties by replicating the surface of Titan in a lab. The research could also yield clues about the chemistry that led to the origin of life on Earth.
