The average background temperature is about 2.7 degrees above the coldest possible temperature (known as absolute zero). Red spots are slightly warmer, while blue spots are slightly cooler. Astronomers hope this map can help them learn more about the history of the universe.

They can be used to detect the light in the universe left over from every star that ever shone. In this image, the blazars are shown as green dots; the Milky Way glows orange in the middle.
