Caption: The South Pole Telescope recorded temperature fluctuations in the cosmic microwave background, the light left over from the Big Bang, to study the period of cosmological evolution when the first stars and galaxies formed early in the history of the universe. The image, only a third of which was used for the current analysis, shows variations in millionths of a degree Kelvin.
