Summary:

- The Cassini spacecraft's observations of Saturn's moon Titan have revealed a potential six-mile-deep crust of solid methane on the moon's surface.
- This methane crust could significantly impact our understanding of Titan's geology and the processes that shape its surface, potentially rewriting planetary science.
- The discovery of this extensive methane crust suggests Titan's surface is more complex and dynamic than previously thought, with implications for the moon's potential habitability and the broader study of planetary bodies in our solar system.
