Titan's Giant Methane Sea is Eerily Calm

Because of its Earth-like weather system, astronomers use Saturn's moon Titan as a model for studying the early history of Earth. A new revelation that the moon's second largest sea, Ligeia Mare, is eerily placid - perhaps as smooth as a mirror's surface - has led scientist to theorize that a lack of surface winds is responsible for the smoothness. The report offers new insights into the weather patterns on the distant moon.
