Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep inside the Red Planet.

By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid water to flood the planet with an ocean thousands of feet deep.

Space Mars May Be Hiding an Ocean of Liquid Water Under Its Surface Seismic data collected by NASA suggests the amount of water hidden in the red planet's crust would cover its surface in a global ...
