Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a ...

NASA’s Perseverance rover has once again delivered a striking glimpse into the Martian environment, capturing a delicate ...

Massive volcanic eruptions billions of years ago may have made it snow on Mars, leaving thick buried ice near the planet’s ...

Creating a composite photograph of the images taken by the Color and Stereo Surface Imaging System (CaSSIS) aboard the Trace Gas Orbiter, ESA scientists found that the dust and gas layers of Mars' ...

For the first time, scientists have caught a key driver of the ongoing erosion of the atmosphere of Mars in action. It took more than nine years' worth of satellite data, but a team led by planetary ...

Slices from the edge of Mars reveal a layered atmosphere of delicate complexity. A European spacecraft has captured a luminous mille-feuille of dust enveloping the red planet in unprecedented detail.

Scientists combined 20 years of Mars images to track over 1,000 dust devils, revealing powerful winds that shape the Red ...

All evidence points to Mars having had a carbon dioxide-rich atmosphere billions of years ago, but insufficient carbonates in Martian soil challenge this theory. Now, a new study using data from ...

Ancient explosive volcanic eruptions on Mars could help explain mysterious hints of buried ice from the Red Planet's equator, ...

It's not entirely clear how neighboring planet Mars went from a presumably life-supporting planet to a place as dead as all others in the solar system. We do know, however, that whatever water and ...

Because oxygen-bearing sulfate minerals trap and preserve signals from Earth's atmosphere, scientists closely study how they ...
