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.

There are literal oceans' worth of liquid water hiding out on Mars. There's just one big problem. That water is actually in Mars, at depths that are too far below the surface for us to access.

If Mars’ crust is similar across the planet, there may be more water within the mid-crust zone than the “volumes proposed to have filled hypothesized ancient Martian oceans,” the authors ...

But that wet period ended more than 3 billion years ago, after Mars lost its atmosphere. Planetary scientists on Earth have sent many probes and landers to the planet to find out what happened to that ...

However, spacecraft investigations during the past 50 years point to a geologically dynamic and water-rich ancient ... long-lived primeval ocean on Mars. Stable oceans open prospects for the ...

NASA's discoveries reveal water's prevalence beyond Earth, from subsurface oceans on moons to vapor in exoplanet atmospheres.

In the study published in Nature Astronomy, the scientists explained that the clay deposits rich in minerals formed when Mars ...

Terraforming Mars could be as easy as one, two, three, we proclaim, reclined in our cushy very-much-on-Earth armchairs.

Satellite data reveals 21% of oceans have darkened, affecting photic zones and marine life. Researchers warn of severe effects on global marine life and ecosystems.
