Detailed explanation-1: -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.
Detailed explanation-2: -"Arno Penzias and Bob Wilson were trying to find the source of excess noise in their antenna, where pigeons were roosting, ‘’ he said. “They spent hours searching for and removing the pigeon dung. Still the noise remained, and was later identified with the Big Bang."
