Description
Astronomers keep calling distant worlds “Earth 2.0,” but how habitable are they really? In this video, we explore some of the most famous exoplanets ever discovered — Proxima Centauri b, TRAPPIST-1e, TOI-700 d, Kepler-452b, Kepler-22b, and K2-18b — and reveal why these so-called Earth-like planets may actually be deadly for human life. From tidal locking, superflares, and crushing gravity to supersonic winds, boiling oceans, hydrogen atmospheres, and extreme pressure, this space documentary breaks down the real science behind habitable zone planets, alien worlds, and the search for life beyond Earth.
