Titan’s hydrocarbon lakes could contain structures called vesicles that strongly resemble cell membranes on Earth. A recent study coauthored by NASA shows that rainfall might provide the energy needed for these vesicles to form.

Could exotic lifeforms be brewing on Titan? Saturn’s largest moon is covered with the carbon-based building blocks of life and is the only place that we know of besides Earth with large lakes on its surface – made from super-chilled methane instead of water. In 2017, NASA discovered that Titan’s thick, hazy atmosphere contains acrylonitrile, a lipid-like molecule that could cluster together within the moon’s lakes to form vesicles. These hollow spheres strongly resemble cell membranes on Earth, but a follow-up study determined that vesicles would be unlikely to form on Titan without an additional source of energy, casting doubt on their emergence. Now, a recent study coauthored by NASA shows that the missing spark could come from rainfall.
