Soaring Over Titan: Extraterrestrial Land of Lakes! Of the hundreds of moons in our solar system, Titan is the only one with a dense atmosphere and large liquid reservoirs on its surface, making it in some ways more like a terrestrial planet. Both Earth and Titan have nitrogen-dominated atmospheres -- over 95 percent nitrogen in Titan's case. However, unlike Earth, Titan has very little oxygen; the rest of the atmosphere is mostly methane and trace amounts of other gases, including ethane. And at the frigid temperatures found at Saturn's great distance from the sun, the methane and ethane can exist on the surface in liquid form.

This colorized movie from our Cassini mission takes viewers over the largest seas and lakes on Saturn's moon Titan. The movie is made from radar data received during multiple flyovers of Titan from 2004 to 2013.
