Flooded canyons found

NASA has said its Cassini spacecraft has found deep, steep-sided canyons on Saturn’s largest moon Titan that are flooded with liquid hydrocarbons. “Finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of canyons hundreds of meters deep.”. Discovery, published in the US the journal Geophysical Research Letters, was based on data collected from close flyby Cassini made over Titan in May 2013, during which the spacecraft’s radar instrument focused on channels that branch out from the moon’ s second largest hydrocarbon sea Ligeia Mare.
