Explanation:
Detailed explanation-1: -The Cosmic Microwave Background (CMB) is the cooled remnant of the first light that could ever travel freely throughout the Universe. This ‘fossil’ radiation, the furthest that any telescope can see, was released soon after the ‘Big Bang’. Scientists consider it as an echo or ‘shockwave’ of the Big Bang.
