Summary
Evolution of all-sky maps of the cosmic microwave background: NASA's COBE (left, launched 1989), NASA's WMAP (centre, launched 2001) and ESA's Planck (right, launched 2009). Each generation imaged the temperature fluctuations with higher resolution and sensitivity, sharpening the pattern of hot and cold spots that encodes the composition and history of the universe.
