Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Mars formed quite rapidly, 4.5 billion years ago, from gas and dust that made up the early solar system. Then, very soon after formation, its interior separated out into a metallic core and a ...

The north pole of Mars is slowly sinking under the weight of an ice cap that only formed within the past few million years. And, in the process, it's telling us something about what the planet's ...

A team of researchers from the German Aerospace Center (DLR) used that ice cap to make surprising discoveries about it and what it tells us about Mars's interior. The research is published in the ...

NASA's $850 million InSight Lander is the first designed to study the interior structure of Mars. Until now, NASA's landers mainly focused on exploring Mars' surface for signs of potential life.

More than 3 billion years ago, Mars intermittently had liquid water on its surface. After the planet lost much of its ...

Water once existed in abundance of at the surface of Mars. How much of that water has been stored in the planet's crust is still unclear, according to a new analysis.

Together, the group has been able to determine the Red Planet’s interior structure and assess the age of its northern polar ice cap. The north pole of Mars is covered by a 1000-kilometre-wide, ...
