Some rivers on ancient Mars flowed for long enough stretches to create bona fide habitable environments on the Red Planet, a new study suggests.
A new technique developed by geologists from the Massachusetts Institute of Technology (MIT) makes use of satellite imagery to investigate alien rivers, their rate of flow and how they move fluid and sediment across the surface of their home worlds. Only two other worlds in the solar system are known to have harbored rivers: Mars, where water flowed billions of years ago, and Saturn's moon Titan, where rivers of methane still run today.
