Underground lake found on Mars

26 July 2018

At a news conference in Rome on Wednesday, scientists say they have found a lake below the surface of Mars. Researcher Roberto Orosei said the discovery came after the European Space Agency's Mars Express spacecraft detected a reflection coming from the planet.

Instruments on board the spacecraft found the lake by transmitting radar pulses that penetrated the Martian surface and ice caps. Those pulses revealed a radar profile similar to that of subglacial lakes found beneath Earth's Antarctic and Greenland ice sheets. And the scientists say it could conceivably contain microbial life. It's a ground-breaking discovery, but researchers say it could take years to find any signs of life in the water.
