Have you ever thought about surfing on an alien world? We can now expand the search for the perfect wave from Earth to the rest of the Solar System, and beyond. Scientists have developed a new model for simulating waves on other planets. Titan is one of the 274 confirmed moons of Saturn to date, and the only object in the solar system (besides Earth) known to have liquid lakes and seas on its surface. The featured video shows a simulation of waves on Earth (right) and on Titan (left), under the same conditions (the scale marker is in meters). A light breeze would create taller, slower-moving waves on Titan than on Earth, because the lakes there are filled with light liquid hydrocarbons, and because of Titan's low gravity and higher atmospheric pressure. In a couple of years, NASA expects to launch the Dragonfly mission, which will travel for 6 years and send a rotorcraft to explore Titan and study its microbial habitability.
