In a nutshell Mars’ missing atmosphere may not have escaped to space as previously thought. Instead, it likely underwent a ...

The thick, mineral-rich layers of clay found on Mars suggest that the Red Planet harbored potentially life-hosting ...

New research suggests that Mars' missing atmosphere, long a mystery for planetary scientists, could be hiding within the ...

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 ...

As the sun grew hotter, so did Mars, prompting much of its atmospheric carbon dioxide to rain out and ultimately get locked ...

Mars used to have a thick, robust atmosphere, or at least that’s what scientists think they know about the history of the Red Planet. Solar wind — the outflow of particles from the Sun — is ...

One of the great unsolved problems in modern planetary science is written on the surface of Mars. Mars has canyons that were ...

MIT research suggests Mars’ missing atmosphere — which dramatically diminished 3.5 billion years ago — could be locked in the planet’s clay-covered crust. Water on Mars could have set off ...

With its iconic rusty hue, Mars has long been called the red planet. Now, scientists may have discovered the potential source of that distinctive coloring, overturning a popular theory in the ...

Mars lost most of that liquid water, which is considered an essential ingredient for life anywhere in the universe. But importantly, this study notes that Mars' redness happened before the water left.
