The Planck mission, an essential milestone in the history of cosmology

Our understanding of the history of the cosmos is marked by a few outstanding discoveries and essential observations. The Planck mission achieved one of them: the “ultimate” map of the intensity of the Big-Bang’s light. “Ultimate” because it covers the entire sky and reveals even the smallest signals of primordial origin with extreme sensitivity.

Twelve publications, all accepted for publication in a dedicated volume of the journal Astronomy and Astrophysics, bring to a close a series of outstanding results on our universe, from the Big Bang to the Galaxy. LPENS researchers led three of these publications. The highlights of the Planck mission are summarized in 5 episodes accessible from this link: http://public.planck.fr/actualites-planck/304-la-mission-planck-un-jalon-essentiel-dans-l-histoire-de-la-cosmologie?utm_campaign
