Summary:
- Titan, Saturn's largest moon, was long believed to have a subsurface ocean, but new research suggests this may not be the case.
- The study found that Titan's interior is likely made up of a solid, icy shell with no liquid ocean beneath it, based on data from the Cassini spacecraft.
- This new understanding of Titan's internal structure could impact future plans for exploring the moon and searching for potential signs of life.
