"In spring, this ice begins to warm up and sublimate. The last remnants of this ice are located on the shaded side of the dune tops, and that is where the blocks break off from once the temperature is ...

A European spacecraft has captured the most detailed images yet of Mars’s upper atmosphere, revealing a delicate, layered structure made of dust and ice particles. Described by scientists as ...

For years, scientists have puzzled over the sinuous grooves found etched across the sand dunes of Mars. These features, ...

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

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

Mars' atmosphere has been of interest to scientists for decades, especially as humanity looks to set up outposts on the Red Planet. Recently, the European Space Agency's ExoMars Trace Gas Orbiter gave ...

Mars’s atmosphere may have once been hundreds of times thicker than it is today, acting as a blanket that protected it from frequent asteroids that ravaged other planets. While the sun and most ...

A thin cloud that appears on Mars each year has baffled astronomers ever since it was first spotted, but it may be the result of a moisture-rich atmosphere that was thought impossible. Each winter, an ...

A schematic of temperature measurements shows how it is 40 degrees Celsius colder inside the north polar vortex (indicated by the yellow line) compared to outside the vortex. A rare glimpse into the ...

The Martian polar vortex exhibits significantly lower temperatures (approximately 40°C colder) within its core compared to the surrounding atmosphere, a phenomenon observed through the use of the ...

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' ...
