exoplanet atmospheres

Exoplanet atmospheres are the layers of gases surrounding planets outside our solar system. They vary in composition—such as hydrogen, helium, water vapor, or methane—and can be thick or thin. Studying these atmospheres helps scientists understand the planet’s climate, weather, and potential habitability. By analyzing how atmospheres absorb and emit light, researchers can learn about their temperature, surface conditions, and possible signs of life. Advances in telescope technology now enable detailed observations of exoplanet atmospheres, providing insights into diverse worlds across the galaxy.
