Researchers have found new evidence for a massive subsurface ocean on Mars, again raising the possibility of microbial life.

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 ...

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

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 ...

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.

In 2024, scientists made headlines when they found evidence of copious amounts of water inside a layer of the Martian crust.

A new study published in the journal Geology provides compelling evidence for the existence of liquid water beneath Mars.

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