Cassini spots mini Nile River on Saturn moon

Cassini's radar imaging of Titan has spotted evidence for a 400 km long river on Titan, with its mouth in a lake. Lakes and rivers on Titan are made of liquid methane/ethane, not water, which is frozen rock-like at Titan's temperatures. The riverbed-shaped structure is apparently full of liquid, not a dry empty riverbed, because it appears dark to the radar, indicating that it has a smooth surface.

I'm not sure why it's compared specifically to the Nile river.

The Nile river comparison is bizarre. At first I thought those two images were the Titan river and the Nile river, and I was like, "WOW those look exactly the same," but then I realized they were both the Nile XD Is it because the Titan river also flows "backwards?" similar lengths? Because they are both the longest rivers on their respective planets? Or just a random well-known river selection?

Either way, this is a really cool find! Way to go, Cassini!
