The new findings, published April 15 in Nature Astronomy, are the first confirmation of just how deep some of Titan's lakes are (more than 300 feet, or 100 meters) and of their composition. They provide new information about the way liquid methane rains on, evaporates from and seeps into Titan - the only planetary body in our solar system other than Earth known to have stable liquid on its surface.
On the eastern side of Titan, there are big seas with low elevation, canyons and islands. On the western side: small lakes. And the new measurements show the lakes perched atop big hills and plateaus. The new radar measurements confirm earlier findings that the lakes are far above sea level, but they conjure a new image of landforms - like mesas or buttes - sticking hundreds of feet above the surrounding landscape, with deep liquid lakes on top.
Titan is the second coolest planet in the system. Go Team Dragonfly.
