In 1964 physicists Arno Penzias and Robert Wilson, working for Bell Laboratories in New Jersey, discovered unidentifiable background 'noise' with a radio telescope. Mystified,
they began a process of elimination which ruled out stars, galaxies, interference from local signals, even bird droppings on their antenna. The source lacked the energy output
of celestial phenomena and the noise was isotropic - coming from everywhere in the sky at once. Their eventual conclusion was that the noise was residual radiation from the
Big Bang. The low energy level explained by it having been created over 13 billion years ago. The two published their findings in the Astrophysical Journal in 1965 and were
awarded the Nobel Prize in Physics thirteen years later.
