NASA’s Cassini-Huygens spacecraft gathered radar knowledge revealing that the small liquid lakes in Titan’s northern hemisphere are surprisingly deep, set atop hills and full of methane, throughout its last flyby of Saturn’s largest moon in 2017. These lakes are greater than 300 toes and supply new details about the best way liquid methane rains on, evaporates from and seeps into Titan, the one different planetary physique in our photo voltaic system identified to have steady liquid on its floor. Titan’s hydrologic cycle is analogous Earth’s, however fairly than water evaporating from seas, forming clouds and rain, Saturn’s moon does all of it with methane / ethane.
