The gravitational redshift of its photons can be described as "integrated" or non-integrated depending on where the last scattering occurs and is known as the Sachs-Wolfe Effect, while the influence of electrons on it through inverse Compton scattering is known as the Sunyaev-Zeldovich effect.

COBE studies the anisotropy of this phenomenon while WMAP measures its temperature. It was hypothesized by George Gamow, and its accidental discovery by Arno Penzias, and Robert Wilson in 1964 was a major blow to the Steady State model of the Universe. For 10 points, name this feature remnant of the Big Bang, whose temperature is about 2.7 Kelvins.
