Detailed explanation-1: -The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the “cosmic microwave background", or CMB.
Detailed explanation-2: -Photons travel in all directions, and are everywhere. The photons that you are able to see, are the ones that started out at a particular distance from you, and in a particular direction, but other photons started out at smaller and larger distances, and in other directions.
Detailed explanation-3: -They concluded that the noise is Cosmic Microwave Background Radiation (CMBR), the remains of energy created after the big bang expansion.
