Beyond the Limits of Observation
This full-sky image of the temperature fluctuations (shown as color differences) in the cosmic microwave background was made from nine years of observations by NASA’s Wilkinson Microwave Anisotropy Probe (WMAP) satellite. These temperature fluctuations are the seeds of galaxies, from a time when the universe was less than 400,000 years old. Credit: NASA
