Exoplanet atmosphere research is a branch of astrophysics focused on studying the atmospheres of planets outside of our solar system. Scientists study the composition, temperature, and dynamics of these atmospheres to better understand the conditions present on these distant worlds. This research is crucial for identifying potentially habitable exoplanets and studying the diversity of planetary atmospheres beyond our solar system. Techniques used in exoplanet atmosphere research include spectroscopy, which allows scientists to analyze the chemical makeup of the atmospheres, and modeling to simulate and understand the atmospheric processes on these exoplanets.
