SINGAPORE (Reuters) - A study released Monday using data from NASA's Mars InSight lander shows evidence of liquid water far below the surface of the fourth planet, advancing the search for life there and showing what might have happened to Mars' ancient oceans.

The lander, which has been on the Red Planet since 2018, measured seismic data over four years, examining how quakes shook the ground and determining what materials or substances were beneath the surface.
