Mars had ‘recent’ running water BBC

Mars appears to have had running water on its surface about one million years ago, according to new evidence.
Images from a NASA spacecraft orbiting the Red Planet show fan-shaped gullies on the surface which seem to be about 1.25 million years old, the study says.
They believe the channels were sculpted by surface water from melting ice.
It may represent the most recent period when water flowed on the planet, a team from Brown University in Rhode Island, US, report in the journal Geology.
