Is There Anybody Out There?
Such as extra-terrestrials or any other signs of life beyond Earth?
Extra-terrestrials or other signs of life - is there anybody beyond planet Earth? Are we alone in space? It wasn’t until the late 1960s that humans started an organised, systematic hunt for intelligent life. We have listened to radio waves, peered through the celestial dust and beamed The Beatles to distant planets. So how’s it going? Is there anybody out there? This is the story of the search for extra-terrestrial life.
