IAU OAE Glossary Entry: Extraterrestrial Life, Exoplanets, and the Search for Life Beyond Earth
To the point
Life beyond Earth may exist on other exoplanets with liquid water, could alter their atmospheres in detectable ways, and scientists search for it by studying distant atmospheres and through SETI’s search for intelligent signals, while moons like Europa and Enceladus in our Solar System may harbor life in their ice‑covered oceans.
