ANSWER: Titan
Nasa's Cassini spacecraft, orbiting Saturn and its moons since 2004, has confirmed that a huge sea on Saturn's moon Titan is composed mostly of pure liquid methane.
- The sea, called Ligeia Mare, has a surface area of about 126,000 sq. kms.
- Cassini also found that the seabed may be covered in a sludge of carbon- and nitrogen-rich material, and its shores may be surrounded by wetlands.
