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

European space researchers have discovered a bizarre phenomenon on Mars: thousands of dark formations resembling giant ...

According to the study, it takes millions of years for deposits like this to form on Earth, so the evidence suggests that Mars once had a large body of water with waves that moved sediment around.

The ripples suggest that the lake was free of ice at one point.

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.

Scientists have found vast oceans of ice lying just below the surface of Mars in a major boost to the search for alien life on the Red Planet. One of the most exciting planetary discoveries ever ...

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 ...

The three-kilometre-thick ice sheet covering Mars's north pole is young, formed between 2 and 12 million years ago. The ice sheet is bending the rocky crust beneath at a rate of 0.13 millimetres per ...

When a mudflat crumbles on Earth, or an ice sheet splinters on one of Jupiter's moons (Europa), or an ancient lakebed breaks ...

The study also showed that the soil on Mars could keep ice near the surface in the middle and lower areas because water vapor moves more slowly there. This means the soil helps trap water for a ...

(Credit: Hai Liu, Guangzhou University, China) According to the study authors, beaches indicate that Mars once had a large, ice-free ocean, back when the planet likely had a warmer and thicker ...
