The Planck legacy - Reinforcing the case for a standard model of
  cosmology: $\Lambda$CDM
  We present a brief review of the main results of the Planck 2015 release
describing the new calibration of the data, showing the maps delivered in
temperature and, for the first time, in polarization, the cosmological
parameters and the lensing potential. In addition we present a forecast of the
Galactic foregrounds in polarization. Future satellite experiments will have
the challenge to remove the foregrounds with great accuracy to be able to
measure a tensor-to-scalar ratio of less than 0.01.
