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

Accurate measurement of atmospheric composition is fundamental to deciphering air quality dynamics, climate interactions, and human exposure risks. Pollutants such as aerosols, ozone, and particulate ...

Astronomers have found some pretty wild exoplanets. Some are balls of lava the temperature of hell, one is partially made of diamond, and another may rain molten iron. However, not all exoplanets are ...

Scientists using NASA's James Webb Space Telescope have observed a rare type of exoplanet, or planet outside our solar system ...

A Carnegie-led team of astronomers detected the strongest evidence yet of an atmosphere around a rocky planet beyond our ...

The Earth’s atmosphere is a complex and dynamic envelope comprised primarily of nitrogen and oxygen, with trace gases such as carbon dioxide, methane, water vapour and ozone playing outsized roles in ...

James Webb Space Telescope observations reveal atmospheric gases above the molten rocky exoplanet TOI-561 b, providing the strongest evidence yet of an atmosphere on a tidally-locked ultra-hot ...

A newly discovered exoplanet, TOI-561 b, is shaking up conventional theories about planetary atmospheres. According to a ...

Scientists using NASA’s James Webb Space Telescope have observed an entirely new type of exoplanet whose atmospheric ...

Astronomers have unveiled the clearest evidence yet of an atmosphere surrounding an exoplanet outside our solar system. The study, led by the Carnegie institution using NASA's James Webb Space Telesco ...

The Daily Atmospheric Ionospheric Limb Imager (DAILI) CubeSat successfully launched aboard the SpaceX Falcon 9 rocket at 5:07 a.m. EST on Dec. 21, 2021 from Launch Complex 39A at NASA’s Kennedy Space ...

Webb telescope observations hint that a scorching rocky exoplanet may hold a thick atmosphere above molten rock, defying ...
