(CNN) A lake of liquid water has been detected by radar beneath the southern polar ice cap of Mars, according to a new study by Italian researchers from the Italian Space Agency, published Wednesday in the journal Science.

Evidence was gathered by the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument, also known as MARSIS, on the European Space Agency's Mars Express spacecraft.

Between May 2012 and December 2015, MARSIS was used to survey the Planum Australe region, which is in the southern ice cap of Mars. It sent radar pulses through the surface and polar ice caps and measured how the radio waves reflected back to Mars Express..................

But how reliable are these detections?

Outside experts have not been able to confirm these findings with other radar detections, like SHARAD, the Shallow Radar sounder onboard the Mars Reconnaissance Orbiter.
