Image 1 / 10

Premiering as part of a special ‘Space Season' on Discovery Science, ‘When Aliens Attack' explores the haunting questions that have been raised by some of the top researchers, scientists and government agencies: What would happen if Earth was invaded by aliens? How would they get here? What would they be like? What kind of weapons would they use? How would alien wars unfold? In this gripping new two-hour special, science is combined with extraordinary CGI, engaging interviews and compelling facts, to reveal a minute-by-minute story of how an alien invasion would be likely to unfold and how we could respond.
