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

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

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 ...

Scientists Ikuo Katayama from Hiroshima University and Yuya Akamatsu from the Research Institute for Marine Geodynamics ...

Because of the absence of liquid water on Mars’ surface today, those rusty red minerals were thought to arise from dry iron oxides present in the dust, such as hematite. But new analysis of ...

Step aside, Santa Monica. It seems that Mars once had beaches that would give the Californian coast a run for its money.

The findings reveal details about conditions on Mars when the planet last contained large volumes of liquid water more than 3 billion years ago. “Early Mars has historically been thought of as ...

NASA's Perseverance rover, which has been exploring Mars since 2021, fired its laser at some oddly pale rocks on the surface ...

A new study in the journal Nature Communications reveals that Mars is red for very much the same reason it may have once been home to life — namely, that it was a wet planet. This is in line with ...

"If liquid water exists on Mars," Katayama says, "the presence of microbial activity" is possible. For example, S-waves cannot travel through water and move at a slower speed than P-waves.
