Titan’s Gigantic Sand Dunes

Titan has a large equatorial desert called the Shangri-la Land Sea, and it features a rather impressive network of sand dunes. These dunes extend across an area measuring over 3.9 million square miles (10 million square km), with some individual dunes reaching as tall as 330 feet (100 meters). Sand dunes on Earth are composed primarily of silicates, but Titan’s dunes are made from organic materials bombarded into existence by the Sun’s cosmic rays, according to recent research.
