NASA Scientist Discovered Mini Nile River on Saturn’s Moon Titan

Scientists from NASA spotted the longest extra-terrestrial river system ever on Saturn’s moon Titan which appears to be a miniature version of Earth’s Nile River.

 As per NASA Jet Propulsion Laboratory, the river valley on Titan stretches more than 400 kilometres from its headwaters to a large sea comparing it with the Nile River on Earth which stretches about 6700 kilometres.

The finding came into in light after NASA’s Cassini mission sent images which revealed for the first time a river system this vast and in such high resolution anywhere other than Earth.

Titan is the only body in the solar system apart from earth which is known to have vast seas and possess a cycle of liquids on its surface.

However, the other evident fact is that the thick Titan atmosphere is a frigid where water could not possibly flow. The liquids on Titan are therefore composed of hydrocarbons such as methane and ethane.

Images from Cassini’s visible-light cameras in late 2010 in Titan’s equatorial regions revealed the regions to be darkened due to recent rainfall. Cassini’s visual and infrared mapping spectrometer confirmed liquid ethane at a lake in Titan’s southern hemisphere known as Ontario Lacus in 2008.

The radar image taken on 26 September 2012 shows Titan’s north polar region, where the river valley flows into Kraken Mare, a sea that is, in terms of size, between the Caspian Sea and the Mediterranean Sea on Earth.
