The Planck satellite was created to study the birth and evolution of the Universe. By studying the "Cosmic Microwave Background Radiation", which is basically the light left over from the Big Bang, we can understand and even measure things like the amount of matter in the Universe, and how fast it is expanding. I will explain how cosmologists do this in general, and how the Planck satellite in particular is contributing to our understanding of the Universe.
