astronomyCassini 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.
