Lights in the Dark

Saturn’s largest moon Titan has often been likened to a primordial Earth, with its thick atmosphere, changing weather patterns, and — most intriguing of all — vast amounts of liquid on its surface in the form of lakes, streams, and rivers. One big difference though: nearly ten times farther from the Sun than we are, temperatures on Titan are a chilly 290 degrees below zero (F) and so the liquid isn’t water, it’s methane… what’s called natural gas on Earth.

Still, methane does a good job replacing water in Titan’s own version of a hydrologic cycle. Methane rain falls to fill streams, carving gullies and canyons through the frozen landscape (where water is harder than rock) and eventually filling methane lakes and seas — some as large as our Great Lakes!
