The methane-filled lakes on Saturn’s moon Titan are explosion craters, model predicts

Science
Sept. 9 (UPI) -- According to a new model developed by planetary scientists in Italy and the United States, many of the methane-filled lakes on Titan were likely formed after explosions of warming nitrogen left dozens of empty craters dotting the surface of Saturn's largest moon. Outside of Earth, Titan is the only planetary body in the solar system known to host stable liquid on its surface. While Earth hosts bodies of water, Titan's lakes are filled with liquid methane and ethane. On Earth, methane and ethane typically exist in gas form, but subzero temperatures on Titan allow the hydrocarbons to exist in liquid form. Previous models suggested Titan's lakes were formed over thousands of years as the liquid methane and ethane precipitated by Titan's clouds dissolving the moon's bedrock ...
