Atmospheric science is the study of the dynamics and chemistry of the layers of gas that surround the Earth, other planets and moons. This encompasses the interactions between various parts of the atmosphere as well as interactions with the oceans and freshwater systems, the biosphere and human activities.
The space telescope has helped to determine the atmospheric composition of an exoplanet using the light spectrum of its host star. Spectral changes as the planet orbits the star reveal the long-sought presence of exoplanetary methane.
Climate change is expected to strengthen atmospheric jet streams. Here the authors show that the fastest upper-level jet stream winds accelerate about 2.5 times faster under climate change than average winds, which could influence aviation and severe weather events.

Air pollution is a leading cause of death globally. Efforts to clean the air will not only save lives but contribute to addressing broader environmental and socioeconomic challenges.
