The Rains in the Plains
NASA’s Cassini spacecraft has captured evidence of large weather systems on Titan. In 2010, astronomers noticed that the parts of the surface had darkened after the passing of rain clouds, suggesting that the areas had become wet after rainstorms.
Much like Earth, Titan has seasonal changes as well as of longer-term climate cycles, which may take place over tens or hundreds of thousands of years. Researchers are now creating models of interactions between Titan’s surface, liquid, and atmosphere in order to better understand these processes.
