Finding Life Beyond EarthS1 Ep2 - Moons

Moons - Scientists used to think our neighbouring planets and moons were fairly boring - mostly cold, dead rocks where life could never take hold. Today, however, the solar system looks wilder than they ever imagined. Powerful telescopes and unmanned space missions have revealed a wide range of dynamic environments - atmospheres thick with organic molecules, active volcanoes and vast saltwater oceans. This ongoing revolution is forcing the experts to expand their ideas about what kinds of worlds could support life. (From the US) (Documentary Series) (Part 2 of 2) G CC
