Titan (Titan) is the largest moon of Saturn. Astronomers revealed that Titan likely formed along with Saturn billions of years ago. Titan appears to have many similar characteristics to Earth. But it’s a very different place. The weather is very cold. Rain and oceans, on the other hand, are made of liquid hydrocarbons such as methane. Water, on the other hand, is frozen until it becomes ice. But on Titan there are sand dunes as well.
A vast sand dune field that covers more than one-eighth of Titan’s surface. These sand dunes are about 100 meters high, 1-2 kilometers wide at the base, and can stretch for hundreds of kilometers. It is thought to have formed naturally on the moon through erosion or condensation from hydrocarbons in the atmosphere. But a team of astronomers at the University of Colorado, USA, suspects that the sand that makes up the dunes is actually the same. It may have come from something outside of Earth, such as a comet. The team proposed the idea that the sand particles are made from tholins, a red substance found in space. They exist throughout the cooler regions of the solar system. which cool hydrocarbons in comets or the outer atmospheres of planets and moons When reacting with ultraviolet light from the sun It will create the complex compound tholin. Tolin formed in Titan’s dry atmosphere. It can be electrostatically coagulated to form small pellets of soot. It then falls to the moon’s surface, creating both dust and sand.
However, a future Titan exploration project using the Dragonfly, an eight-rotor drone that plans to reach the moon Titan in 2034, will fly to dozens of locations on its surface. Titan It may provide the true answer to whether Titan’s sand dunes are actually made from comet dust?
