Robert Woodrow Wilson (born January 10, 1936) is an American astronomer who, along with Arno Allan Penzias, discovered cosmic microwave background radiation (CMB) in 1964.
The pair won the 1978 Nobel prize in physics for their discovery.
While working on a new type of antenna at Bell Labs in Holmdel Township, New Jersey, they found 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.
