  00:06:00  2014  HD 16/9  Color  Sound

The Planck satellite started to observe the universe in August 2009. In 2013, the images collected enabled scientists to extract information about the structure of the universe, focusing their research on polarization in 2014. It is a property attributed to light which is the latest testimony of the interaction between light and matter.
François Bouchet, cosmologist and Jean-Loup Puget, astrophysicist give a mid-term report on the results of Planck. They answer the following questions:
- Does dark matter undergo annihilations?
- What is the role of neutrinos?
- What about magnetic fields?
