Extra-terrestrial life is ‘inevitable’

Astronomers are standing on a "great threshold" of space exploration that could see evidence of extra-terrestrial life being discovered in the next 20 years, an expert has claimed.

Life beyond the Earth seems “inevitable” given the immensity of the universe, according to US planetary scientist Dr Sara Seager.

Chemical fingerprints of life in the atmospheres of planets could be found by super space telescopes.
