Fluid-rock interactions on ancient Mars may have produced abundant magnetic minerals that preserved unusually intense records ...

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.

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

For centuries, Mars has captivated scientists and the public alike with its striking red hue. Early astronomers speculated that the planet’s color came from iron-rich minerals, much like rust on Earth ...

Mars’ thick crust may have been a hidden engine of geological activity, producing granitic magmas and sustaining underground ...

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 ...

These studies show that Mars is bombarded by meteorites far more often than previously thought — about 2.5 times more ...

Mars' crust, which sits on top of a mantle of molten rock similar to the one inside Earth, is also thicker in the southern highlands. This planetary imbalance is known as the "Martian dichotomy." ...

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 ...

our results highlight the value of geophysical measurements and better constraints on the mineralogy and composition of Mars’ crust,” the authors wrote. The findings are published in the ...

Life on Mars? Planet Earth has turned up tantalizing evidence that there could be after researchers found dense concentrations of microbial cells in cracks of ancient crust deep below the seabed.

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