A New River found on Titan

Titan is the largest moon of Saturn, and recently the Cassini Spacecraft has found what ‘could be the longest river system seen beyond Earth’

The River valley on Titan is more than 400km from its ‘headwaters’ to a big sea, which is believed to be made up of mainly ethane and methane.

Rivers were found on Titan a while ago, when the Cassini dropped a spacecraft onto Titan. In fact, (quoted from Sky and Telescope) “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.”

However, this discovery still surprised scientists as it is a lot larger than expected. In fact, this new river is over 250 miles long, which is around the same length of the Thames.
