A detection of phosphine in the atmosphere of a brown dwarf 54 light-years from Earth deepens the mystery of phosphorus chemistry throughout the Milky Way. An ancient object more than 10 billion years ...

A new study shows that a specific type of silicone, the so-called methylsiloxanes, is widely present in the atmosphere across ...

A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere ...

Mars’ north polar vortex locks its atmosphere in extreme cold and darkness, freezing out water vapor and triggering a dramatic rise in ozone. Scientists found that the lack of sunlight and moisture ...

Hydroperoxides are strong oxidants that have a significant influence on chemical processes in the atmosphere. Now, an international research team involving the Leibniz Institute for Tropospheric ...

The atmospheric chemistry of hydroxyl radicals and gas‐phase reactions is central to our understanding of air quality and climate dynamics. Hydroxyl radicals (•OH), often described as the “atmospheric ...

Artificial intelligence (AI) is transforming how atmospheric composition and chemical processes are observed, interpreted, and modeled. The complexity of atmospheric chemistry—shaped by nonlinear ...

Nitrates in the atmosphere reduce air quality and play an important role in climate change. An international team led by Hokkaido University researchers has revealed how chemical processes in the ...

This report summarizes the rationale and need for supporting a comprehensive U.S. research program in atmospheric chemistry; comments on the broad trends in laboratory, field, satellite, and modeling ...
