Detailed explanation-1: -The cosmic microwave background (CMB ) is a reverberation or afterglow left from when the universe was about 300, 000 years old. It was first discovered in 1964 as a ubiquitous faint noise in radio antennas.
Detailed explanation-2: -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-3: -Robert W. Wilson (left) and Arno Penzias pose next to their antenna after winning the Nobel Prize in 1978 for discovering the Big Bang’s afterglow. Wilson was born and raised in Houston.
