Longest extraterrestrial River discovered on Saturn’s moon Titan

Images from NASA’s Cassini mission have revealed the existence of the longest extraterrestrial river system ever – on Saturn’s moon Titan – and it looks like a small version of Nile River on Earth.

The river valley on Titan is more than 400 kilometres which flows into Kraken Mare, a sea that is, in terms of size, between the Caspian Sea and the Mediterranean Sea on Earth.

Titan possesses vast seas and it is only other body in the solar system, apart from Earth, to possess a cycle of liquids on its surface. But it has a frigid atmosphere which doesn’t allow liquid water to flow. It is for this reason the liquids on Titan are composed of hydrocarbons such as methane and ethane.
