Robert Woodrow Wilson (born January 10, 1936) is an American astronomer who shared the 1978 Nobel Prize in Physics with Arno Penzias "for their discovery of cosmic microwave background radiation".
While doing tests and experiments with the Holmdel Horn Antenna at Bell Labs in Holmdel Township, New Jersey, Wilson and Penzias discovered a source of noise in the atmosphere that they could not explain. After removing all potential sources of noise, including pigeon droppings on the antenna, the noise was finally identified as CMB, which served as important corroboration of the Big Bang theory.
