exoplanet atmospheric characterization

Exoplanet atmospheric characterization involves studying the gases and conditions of planets outside our solar system. Scientists observe light from a star as a planet passes in front of it, analyzing how the star's light changes. This reveals the presence of specific molecules like water vapor, carbon dioxide, or methane in the planet's atmosphere. By understanding these atmospheric components, researchers learn about the planet’s climate, weather, and potential habitability. These techniques help us learn whether distant worlds might support life or have conditions similar to Earth.
