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.

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 ...

For years, scientists believed that Mars was a dry and barren world. However, recent research has revealed something ...

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

Water has been detected on Mars that could harbour life 12 miles beneath the surface, according to new research.

A new analysis of data collected by NASA’s InSight mission suggests there may be enough water beneath the surface of Mars to cover the planet.

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 ...

Deep beneath NASA’s InSight lander, an ocean’s worth of liquid water may be trapped in rocky fissures, suggests a recent study of data recorded during more than 1,300 Marsquakes.

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 ...

A new study posits that dark streaks originally believed to be signs of water on Mars' surface might not be that at all.

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.

CAPE CANAVERAL, Fla. (AP) — 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 ...
