Scientists announced Wednesday that they’ve found evidence of a large body of water beneath the surface of Mars. It may not be little green men, but it’s pretty darn cool.
The announcement, which comes less than two months after the Curiosity Rover found evidence of organic molecules on Mars, adds one more piece to the puzzle for scientists searching the planet for signs that it could support life — or at least could have in the past. And while scientists have long known that Mars used to have liquid water billions of years ago, the fact that it could still have water is a big deal since there’s a possibility that this water may host living organisms.
The researchers involved in the discovery, a team of Italian astronomers and physicists, published their findings in a paper in the journal Science. In the paper, the team presents evidence collected from May 2012 to December 2015 by the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) experiment aboard the Mars Express spacecraft that shows evidence of a large body of liquid water.
