Chemical reactions in the Arctic atmosphere are accelerating warming and reshaping climate far beyond the polar region.

Climate change is racing ahead in the Arctic, and a team of scientists just mapped out how the region’s chemistry is helping ...

"We reported hints of methane, but the question is, 'is the methane attributable to molecules in the atmosphere of the planet or in the host star?'" ...

The oxygen in Earth's atmosphere is key to making ours the only planet known to harbor life, but this precious resource is in limited supply. Although it is the best-known component of the air we ...

The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of ...

JWST observations of exoplanet TRAPPIST-1d reveal a lack of a substantial, Earth-like atmosphere, as indicated by a "flat" spectral signature lacking typical atmospheric molecule fingerprints (e.g., ...

Scientists have discovered trace gases from Earth reaching the Moon, revealing unexpected interplanetary connections and ...

Between 30 and 60 miles above Earth’s surface lies a largely unstudied stretch of the atmosphere. It’s too high for airplanes and weather balloons, too low for satellites and nearly impossible to ...
