Seeking Life Beyond Earth: Exoplanet Atmospheres, Icy Moons, and Citizen Science
To the point
Scientists search for life by analyzing atmospheres of distant Earth-like planets with the James Webb Space Telescope for biosignature gases, while also exploring Mars and Europa for subsurface life, guided by extremophiles and habitable‑zone ideas, with examples like K2-18 b and missions Perseverance, Curiosity, Europa Clipper, and citizen‑science efforts aiding the hunt.
