This is not one those films that claims to have conclusive proof, but rather a look at the serious science of the search for extraterrestrial life.
The search for extra-terrestrial life has been going for 50 years – but there’s been a recent breakthrough. Astronomers have discovered a new planet called Gliese 581 c.
It is the most Earth-like planet ever found. It orbits a star and may have habitats capable of supporting life. NASA hopes to find 50 more Earth-like planets by the end of the decade, all of which increases the chance that alien life has begun elsewhere.
