When the surface of the Sun exploded with activity in May 2024, Earth was hit by the biggest solar storm in more than two ...

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a ...

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 ...

What happens to Mars’ atmosphere when it gets hit with space weather? This is what a recent study published in Nature Communications hopes to address | Space ...

A storm from the Sun can make a planet’s sky glow or a spacecraft’s computer stumble. At Mars in May 2024, it did both, just ...

Mars' missing atmosphere may be locked up in the planet's clay-rich surface, a new study by MIT geologists has suggested. According to the researchers, ancient water trickling through Mars' rocks ...

Researchers say they have gathered evidence of Mars' atmosphere sputtering for the first time. Understanding how Mars' atmosphere has changed over time will undoubtedly help us discover more about the ...
