Scientists have found that the tough shell of Saturn's largest moon Titan is stronger than previously thought and hints at an unusual interior.
The tough icy shell of Saturn's largest moon Titan is apparently far stronger than previously thought, researchers say.
These surprising new findings add to hints Titan possesses an extraordinarily bizarre interior, scientists added.
Past research suggested Titan has an ocean hidden under its outer icy shell 30 to 120 miles (50 to 200 kilometers) thick. Investigators aim to explore this underground ocean in the hopes of finding alien life on Titan, since virtually wherever there is water on Earth, there is life.

To learn more about Titan's icy shell, planetary scientist Doug Hemingway at the University of California, Santa Cruz, analyzed the Cassini probe's scans of Titan's gravity field. The strength of the gravitational pull any point on a surface exerts depends on the amount of mass underneath it. The stronger the pull, the more the mass.
