Scientists have discovered a massive hidden water reservoir 700 km beneath Earth's surface, possibly holding more H₂O than ...

Overpumping groundwater, worsening droughts and more rapid evaporation due to higher temperatures have caused a drastic ...

This reservoir of water could be part of a much larger and more complex whole-Earth water cycle that scientists have only begun to understand. The implications of this discovery extend beyond Earth.

They found evidence of what appears to be a large underground reservoir of water, enough to cover the entire planet in about a mile of ocean. But it’s inaccessible, being located between 7 to 13 ...

Now, after combining this seismic data with models used on Earth to map underground oil fields and aquifers, the researchers determined that igneous rocks (cooled magma) are drenched in liquid water ...

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 ...

Many of America’s critical sources of underground water are in a state of rapid and accelerating decline, a new study has found. More than half of the aquifers in the United States (53 percent ...
