Just as Charles Darwin once used the fossil record to tell the story of the evolution of life on Earth, astronomers are using the first light to shine in the universe to understand the events that shaped the cosmos.

The CMB carries the signatures of the physical processes of the early universe and has unique characteristics that can be used to determine the composition of the universe.
