Saturn's largest moon, Titan, has a thick atmosphere. Clouds. Complex organic molecules. NASA has called it "one of the most Earth-like worlds we have found to date." With one glaring exception. "It's awfully cold down there. It's about 94 degrees Kelvin. Which means that water would be a rock." Paulette Clancy, a chemical engineer at Cornell University. At temperatures that cold—minus 290 degrees Fahrenheit—one of the most basic biological structures, the cell membrane, can't exist. Because to form, the oily membranes depend on the presence of liquid water. That said, Titan does have plenty of liquid to go around—but it's liquid methane. So Clancy and her colleagues used computer models to determine whether any molecules on Titan might mimic the membrane-forming compounds here on Earth.
