Methane is common on the cold giants of our solar system, but it has been missing from one important middle ground: giant ...

A planet that is about the size of Saturn, but with a temperature more like Earth's, has an atmosphere rich in methane, ...

James Webb Space Telescope exoplanet weather observation confirms the first daily cloud cycle ever detected outside our solar system, revealing that a decade of hot Jupiter atmospheric composition ...

Aerosol dynamics and atmospheric composition modelling encompass the study of airborne particulate matter and reactive gases from their emission through to removal. Key processes include nucleation, ...

Researchers using NASA's James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky planet outside our solar system. Observations of the ultra-hot super-Earth TOI ...

The Earth’s atmosphere is a dynamic blend of uniform gases—primarily N₂ and O₂—and variable constituents including water vapour, CO₂, CH₄ and trace species such as O₃. These components undergo a web ...
