The Planck legacy - Reinforcing the case for a standard model of cosmology: ΛCDM

We present a brief review of the main results of the Planck 2015 release describing the new calibration of the data, the maps delivered in temperature and, for the first time, in polarization, the cosmological parameters and the lensing potential. In addition, we present estimates of the Galactic foregrounds in polarization: future satellite experiments will have the challenge to remove foregrounds with great accuracy to be able to measure tensor-to-scalar ratios less than ∼ 0.01.
