Enormous hidden ocean discovered under Mars could contain life

Geophysicists have mapped a massive underground water reservoir on Mars, using seismic data from NASA's InSight Lander. This reservoir contains enough liquid to cover the entire planet and could potentially harbor life.

The cause of Mars' ancient surface water loss remains unclear, with possibilities including magnetic field loss or microbial climate change. The study suggests that Mars may have an ocean's worth of water hidden beneath its surface, 7-12 miles deep.

This water likely seeped from the surface billions of years ago when Mars had rivers, lakes, and possibly oceans. Confirming the presence of water and seeking signs of microbial life would require further exploration with drills and other equipment.

The discovery of this enormous hidden ocean provides new insights into the Martian water cycle and the potential habitability of the planet.
