Ligeia Mare is one of the many bodies of liquid in and around the north polar region of Saturn’s largest moon, Titan. The lake is liquid, but the liquid isn’t water, which would freeze at Saturn’s distance from the sun. The temperature at Titan’s surface is about -289 degrees Fahrenheit (-178 degrees Celsius). Instead, the liquid in this Titan lake is mainly methane and ethane as well as other liquid hydrocarbons.
The lake’s name comes from one of the beautiful and dangerous sirens in Greek mythology, Ligeia. The sirens were said to sing so sweetly that passing sailors would shipwreck on the rocky coast of their island.
Ligeia Mare is second in size only to another lake, Kraken Mare, on Titan. It measures approximately 260 miles by 217 miles (420 km by 350 km) and has a shoreline that’s longer than 1,240 miles (2,000 km)! A day at the beach, anyone?
