From Ozma to Exoplanets: The Modern Quest to Find Life Beyond Earth

To the point

From ancient questions to modern science, we now search for life beyond Earth by listening for technosignatures and by exploring Mars, icy moons, and distant worlds, with private funding from Yuri Milner’s Breakthrough programs and debates on messaging that Stephen Hawking weighed in on, while missions such as Viking, Cassini-Huygens, Perseverance, Europa Clipper, and Dragonfly, aided by JWST and next‑gen telescopes, reveal possible habitats and biosignatures and keep alive the question of whether we are alone.
