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 ...

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 ...

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 ...

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 ...

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 ...

Mars changed from a blue world with water to a red desert because its atmosphere escaped into space over billions of years.

Geochemists are challenging commonly held ideas about how gases are expelled from the Earth. Their theory could change the way scientists view the formation of Earth's atmosphere and those of our ...
