Dramatic new pictures suggest Mars has flowing liquid water on its surface, significantly increasing the possibility of current life on the planet.
Before-and-after images of gullies on the planet taken by NASA’s Mars Global Surveyor show liquid has flowed on the Red Planet in the last five years.
Scientists have previously pointed to features that suggest flowing water on Mars billions of years ago and have collected images of ice at the Martian north pole. The discovery is unexpected because the planet’s temperatures and atmospheric pressure are too low to allow water to exist in liquid form for long.
