There is another way forward. A circular economy for space applies the same principles that aims to transform modern waste policy on Earth. This means designing products to last and keep them in ...

Observational data suggest models are likely underestimating the amount of methane lost through atmospheric chemistry ...

When we look up at the night sky and see a satellite glide past, we might not consider climate change or the ozone layer. Space may feel separate from the environmental systems that sustain life on ...

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 ...

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

Of the 6,000 exoplanets known, a very thin slice of them are in the geometry required to perform a deceitfully simple experiment: observe a planet cross its star and read the atmospheric chemistry ...

A plume of upper-atmospheric lithium pollution observed in February 2025 has been attributed to the reentry of a specific ...

Criegee intermediates are transient carbonyl oxide species generated during the ozonolysis of alkenes, and they play a pivotal role in atmospheric oxidation processes. Their formation initiates a ...

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 ...

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 ...

What’s the first thing you do after waking up each morning, before you’ve even gotten out of bed? For many people, it’s checking the weather. For most, this is a thoughtless chore, an unexciting daily ...
