Unlike surface water, ... scientists have searched for signs of deep water beneath the crust. ... that occurs between 520 and 660 km below the surface of the earth in the transition zone.

Dark “slope streaks,” likely resulting from dust avalanches, stretch across an area of Mars called Acheron Fossae in this ...

This subsurface water layer potentially holds between 520 to 780 meters of global equivalent layer (GEL). GEL measures the depth if all the water was evenly spread across Mars’ surface.

Seismic data from Mars, analyzed using the SEIS instrument from NASA's InSight lander, suggests the presence of liquid water beneath the Martian surface.

New research suggests Mars could have enough water under its surface to form a global ocean. On Monday, scientists released their findings, which are based on seismic measurements captured from ...

The water most likely would have seeped from the surface billions of years ago, when Mars harbored rivers, lakes and possibly oceans, the study's lead scientist said. IE 11 is not supported.

A team of geologists drilled through strange formations dotting the Great Salt Lake's drying playa, and were surprised by what they found.

There's an acidic zone 13,000 feet beneath the ocean surface — and it's getting bigger News By Mark John Costello , Peter Townsend Harris published 13 August 2024 ...

Previous studies estimated that there could be enough water deep underground on Mars to cover the surface in a global ocean between 0.62 to 1.24 miles (1 and 2 kilometers) deep.

But one of the most stunning discoveries lies not in space or on the surface, but deep beneath our feet. Far below Earth’s crust, nearly 400 miles down, scientists found something astonishing: a ...

Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests.. The findings released Monday are based on ...
