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
