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.

Can We Find Life? - NASA Science

So far, the only life we know of is right here on planet Earth. But NASA is looking for signs of life in our solar system and on some of the the thousands of planets weve discovered beyond it, on exoplanets. We can probe alien atmospheres for biosignatures, which could indicate life below.
