Methane Rain

For Saturn’s largest moon, springtime means showers of methane. NASA’s Cassini spacecraft recently saw a “large, dark puddle appear in the wake of a storm cloud” near the deserts of Titan’s equatorial area.


On Titan, where temperatures drop to minus-297 degrees Fahrenheit, polar lakes are filled with methane instead of water. Cloud systems moving from south to north during the changing seasons drop the methane.
