Detailed explanation-1: -With their discovery of the cosmic microwave background in 1964, Arno Penzias and Robert Wilson placed the seal of approval on the Big Bang Theory and shared the 1978 Nobel Prize in Physics for their discovery.
Detailed explanation-2: -Bell Labs’ Horn Antenna in Crawford Hill, NJ-In 1964 while using the Horn Antenna, Penzias and Wilson stumbled on the microwave background radiation that permeates the universe.
Detailed explanation-3: -The CMB radiation was discovered by chance in 1965. Penzias and Wilson, two radio astronomers in the United States, registered a signal in their radio telescope that could not be attributed to any precise source in the sky. It apparently came from everywhere with the same intensity, day or night, summer or winter.
