Big River on Titan

[Deano]

Rivers on Titan aren’t a new discovery.
Since NASA’s Cassini spacecraft dropped the tag-along ESA Huygens probe onto the haze-swathed moon in 2005, Titan has made surprising scientists its day job. Seasonal lakes grow and wane at the poles, while the largest dunes in the solar system gird the moon’s waist. There are river deltas, canyons, and even a sea as large as Lake Superior in North America.
These bodies are filled not by liquid water, but by liquid methane and ethane.
This particular river is more than 400 kilometers (250 miles) long. That’s about the length of the Thames in England, and less than 10 percent the length of the Nile. In terms of the ratio between a river’s length and the diameter of its parent body, the Titan river only rises to Rhine status: the alien river is about 8 percent of Titan’s diameter.
