Artist view of ESA's Planck observatory mapping the earliest light of the universe. Planck is the first european mission to study the relic radiation from the Big Bang. Ever since the detection of small fluctuations in the temperature of this radiation, called Cosmic Microwave Background, astronomers have used the fluctuations to understand both the origin of the Universe and the formation of galaxies.
