Arno Penzias and Robert Wilson discovered the Cosmic Microwave Background Radiation (CMBR) in 1965 while working with a sensitive microwave receiver at Bell Labs. They initially encountered a persistent noise that they couldn't attribute to any known sources, including their equipment or the Milky Way. After ruling out various potential causes, they realized that the noise was actually the remnant radiation from the Big Bang, providing strong evidence for the Big Bang theory. This groundbreaking discovery earned them the Nobel Prize in Physics in 1978.
