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

An arrowhead-shaped rock on Mars sporting features that may hint at ancient microbial activity on the Red Planet has left ...

Since its arrival on the Martian surface five years ago, NASA’s Perseverance rover has been busy scouring the Red Planet for ...

Are subterranean lifeforms viable on Mars? A new interpretation of Martian seismic data by scientists Ikuo Katayama of ...

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.

Their discovery showed that even tucked away in our innards – in the walls of our stomachs, subjected to vinegar-like pH ...

If Mars ever hosted microorganisms in its bygone oceans, their fossils might still be preserved in minerals—and now, we have ...

Research published late last year indicated “seismic discontinuities in the Martian crust” that scientists believe could be an indicator of liquid water under the Martian surface, raising the ...

Mars’ thick crust may have been a hidden engine of geological activity, producing granitic magmas and sustaining underground water reservoirs. A new study suggests that radioactive heating in the plan ...

Many studies suggest then presence of water on ancient Mars billions of years ago,” said Katayama in a statement. “But our ...
