By 3.6 billion years ago, Mars should have become too cold for liquid water, but something kept the rivers flowing.

During Martian winter, a layer of carbon-dioxide ice settles out on top of the polar caps of water ice. While it is just a thin layer on the north polar cap, the south polar cap has much more ...

By doing so, his model encapsulates the full carbon dioxide cycle from the regolith, to atmosphere, to frozen polar caps. For this study, he applied the model to a pivotal era in Mars' history.

For the first time, researchers have quantified the global emissions of a sulfur gas produced by marine life, revealing that ...

Peter Buhler, a research scientist at the Planetary Science Institute, has modeled a new suggestion: that carbon dioxide condensed out of Mars’ atmosphere in a glacier nearly 0.4 mile (0.6 ...

The research proposed that carbon dioxide ice settling on Mars' south polar region could explain how the planet's largest features, like its biggest lake, valleys and ridges, were formed. Scientist ...

One factor that plays a role in ultimately determining the degree of frigidity is a polar vortex. But what is a polar vortex, exactly? The polar vortex is an expansive area of low pressure in the ...

Iceland is no stranger to volcanos. In fact, as a volcanic island shaped by the magma rising out of the mid-ocean ridge it ...

There is a chasm between global climate policy-making elite and activists and researchers who see the world hurtling towards ...
