Troy, N.Y. – Geochemists at Rensselaer Polytechnic Institute are challenging commonly held ideas about how gases are expelled from the Earth. Their theory, which is described in the Sept. 20 issue of ...

Researchers have discovered argon trapped in air-hydrate crystals in ice cores, which can be used to reconstruct past temperature changes and climate shifts. On the massive sheets of ice that stretch ...

Solar wind has slowly torn away Mars’ atmosphere over time, helping to transform a planet that was once warm and wet into the cold, dry, inhospitable one we see today. Chemical sleuths explain in a ...

Mars may have once possessed an atmosphere about as thick as Earth’s, but then lost most of it to space due to solar wind and ultraviolet rays, a new study found. The new finding could shed light on ...

Most scientists agree that Mars once had a vibrant atmosphere similar to the Earth’s. Such an atmosphere would have differed slightly in composition from that of the atmosphere on Earth, but ...

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 ...

For years, scientists have puzzled over how Mars lost the thick atmosphere it once had. That atmosphere was essential for liquid water to exist on the planet’s surface, billions of years ago. Today, ...

It vanished into thin air. Around 90 per cent of the Red Planet’s atmosphere was probably lost to space over just a few hundred million years, according to a key measurement from NASA’s Mars ...
