Detailed explanation-1: -Ligeia Mare, shown in here in data obtained by NASA’s Cassini spacecraft, is the second largest known body of liquid on Saturn’s moon Titan. It is filled with liquid hydrocarbons, such as ethane and methane, and is one of the many seas and lakes that bejewel Titan’s north polar region.

Detailed explanation-2: -Titan is an icy moon with a surface of rock-hard water ice, but Titan also likely has a liquid water ocean beneath its surface.

Detailed explanation-3: -Saturn’s largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere. Titan is the second largest moon in our solar system. Only Jupiter’s moon Ganymede is larger, by just 2 percent. Titan is bigger than Earth’s moon, and larger than even the planet Mercury.

Detailed explanation-4: -The Huygens probe detached from Cassini and parachuted through Titan’s atmosphere, landing on the surface on Jan. 14, 2005-the first landing of a probe in the outer solar system.

Detailed explanation-5: -Based on the observations, scientists announced “definitive evidence of lakes filled with methane on Saturn’s moon Titan” in January 2007. The Cassini–Huygens team concluded that the imaged features are almost certainly the long-sought hydrocarbon lakes, the first stable bodies of surface liquid found off Earth.
