This animation explains how the wealth of information that is contained in the all-sky map of temperature fluctuations in the Cosmic Microwave Background (CMB) can be condensed into a curve known as the power spectrum. The temperature of the CMB exhibits fluctuations on a variety of angular scales on the sky. WebThe Cosmic Microwave Background (CMB) radiation field is an open window to the early Universe. It isa nearly-uniform and isotropic radiation field, which exhibits a measured perfect black-body spectrum at atemperature of 2.72K. This primordial radiation field is a prediction from a Big Bang universe - if in its earlystages the Universe was at a hig...
