Titan harbors about 2,000 cubic miles of liquid methane and ethane on its frigid surface. The hydrocarbons are contained in an area near Titan’s north pole that’s just 660,000 square miles in size, a region slightly larger than Alaska.
The lakes and seas on Saturn’s largest moon Titan hold massive amounts of liquid hydrocarbons — 40 times more than are found in Earth’s proven oil reserves, new observations by NASA’s Cassini spacecraft suggest.
Titan, which is about 1.5 times bigger than Earth’s moon, harbors about 2,000 cubic miles (9,000 cubic kilometers) of liquid methane and ethane on its frigid surface, researchers announced last week. The hydrocarbons are almost all contained in an area near Titan’s north pole that’s just 660,000 square miles (1.62 million kilometers) in size, a region slightly larger than Alaska.
The find indicates there is something favorable in the geology that restricts most liquid to Titan’s northern hemisphere, researchers said. The prime suspect is regional extension of the moon’s crust, a process that on Earth created fault lines with depressions and mountain ranges parallel to each other.
