When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacuglar fireball that ...

According to Alex Turner, assistant professor in atmospheric and climate science at UW, the specific gases researchers focus on depends on the timescale they care about. Methane has a larger effect on ...

Of the 6,000 exoplanets known, a very thin slice of them are in the geometry required to perform a deceitfully simple ...

During the COVID-19 pandemic, the atmosphere temporarily lost its ability to break down methane, leading to a huge spike in the greenhouse gas.

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

Atmospheric methane rose faster than ever in the early 2020s, driven less by fossil fuels and more by changes in nature itself.

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 ...

Climate change makes nitrous oxide disappear faster, creating new uncertainty for future climate and ozone predictions.

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 ...

Harvard University researcher Michael McElroy made groundbreaking contributions to climate science and helped shape global ...

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 ...
