A NASA satellite has spotted frozen "kidney beans" on Mars' sand dunes trapped in place until springtime. Photographing them can help us determine if there was ever enough water on Mars to sustain ...

NASA's Rover found ripples in Martian rock that resemble the wave patterns on a sandy lake bed on Earth. The ripples could ...

Scientists confirm the existence of liquid water on Mars, altering our understanding of the Red Planet. Evidence of wave ...

A study of volcanic cones near the equator on Mars is challenging what scientists previously knew about when and where water flowed on Mars.

The 3.7-billion-year-old formations in the planet's Gale Crater suggest the presence of long-gone bodies of liquid water, with no ice covering the surface ...

Water in the form of frost has been detected on the highest volcanoes on Mars. Researchers found that the red planet's Tharsis volcanoes - the tallest in the solar system - have "on and off ...

In the image below, cooler colors indicate water ice nearer the surface. The box represents an area that would be suitable for a crewed Mars mission to land, according to the scientists.

It was recently put forward that scientists know Mars was home to liquid water for at least 200 million years – but frost existing in this quantity right now is potentially much more significant ...

NASA's Mars Reconnaissance Orbiter captured images ... computer modelling to demonstrate that sunlight can penetrate water ice enough to allow photosynthesis in shallow meltwater pools.
