For decades, scientists have theorized about how Mars reached its current state. Many believe that the Red Planet's surface ...

Mars has lost immense amounts of water over it lifetime, and scientists aren't sure exactly how. New research hints that the ...

Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water -- enough to fill oceans on the planet's surface.

Huge stores of water have been found deep inside Mars, thanks to a seismometer on NASA's InSight mission.

Researchers have identified what they believe could be oceans' worth of water on Mars. There's just one snag: it's deep underground.

Volume of Water: If the findings are representative of Mars globally, there could be enough water to cover the entire planet in a layer about 1 to 2 kilometers deep. This volume suggests that Mars ...

Water has been detected on Mars that could harbor life 12 miles beneath the surface, according to new research. Seismic data from NASA's Insight Lander indicates deep, porous rock filled with ...

Seismic analysis of data from NASA’s InSight lander could be a remnant of Mars’ watery past and raise prospects for life below Mars’ surface.

The good news is that there's a vast ocean of water under the surface of Mars – enough to cover the entire planet to a depth of a mile (1.6 km). The bad news is that this repository is so deep ...

By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid water to flood the planet with an ocean thousands of feet deep.

Enough water to cover the surface of Mars has been discovered within the crust of the Red Planet by NASA's InSight mission. The ocean is buried between one and two kilometers (0.62 and 1.24 miles ...

Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet's surface.
