Planck mission releases CMB map

A spectacular new map of the "oldest light" in the sky has just been released by the European Space Agency. It was acquired by the Planck telescope.

Scientists say the map's mottled pattern is an exquisite confirmation of our Big-Bang model for the origin and evolution of the Universe.

Planck researchers George Efstathiou and Jo Dunkley discuss the results with Adam Rutherford.
