Caption: Holmdel horn antenna, Bell Laboratories, New Jersey, USA. While using this radio antenna (between 1963-64) US astrophysicists Robert Woodrow Wilson and Arno Allan Penzias unexpectedly discovered the universe's microwave background radiation. This evidence for the 'big bang' theory origin of the universe was predicted in 1948 by Gamow and Herman. The discovery won Woodrow and Penzias the 1978 Nobel Prize for Physics.
