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 ...

Scientists know that millions of years ago, Mars was covered in oceans, but the planet lost its water over time and now has virtually no liquid water on its surface. Now, though, researchers have ...

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 ...

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

As for today, the environments on Mars that could potentially support life are few and far between, and it's all about ...
