Scientists have been looking for liquid water on Mars for decades. Valleys and basins and rivers point to the planet’s watery past but H20 has proved elusive. Until now. The Italian Space Agency announced that researchers have detected signs of a large, stable body of liquid water trapped below a mile of ice near Mars’ south pole, according to Wired.
The observations were recorded by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument, known as Marsis.
Roberto Orosei —who led the investigation and is a radioastronomer at the National Institute for Astrophysics — told Wired that “Marsis was born to make this kind of discovery, and now it has.”
This discovery raises questions about the planet’s geology and whether or not Mars could harbor life.
