Detailed explanation-1: -On May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias discovered the cosmic microwave background radiation (CMB), the ancient light that began saturating the universe 380, 000 years after its creation. And they did so pretty much by accident.
Detailed explanation-2: -Their determination in 1964 that the entire sky seemed to be dimly glowing with radio light confirmed physicists’ predictions and later earned Penzias and Wilson a Nobel Prize. The two scientists had, quite by accident, discovered the fading flash from the big bang.
Detailed explanation-3: -A Science Odyssey: People and Discoveries: Penzias and Wilson discover cosmic microwave radiation.
Detailed explanation-4: -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.
