After launched in 2009 by ESA, the Planck satellite was shut off in 2013 with measurements that exceeded all expectations. They include a "definitive" map of the anisotropies of the Cosmic Microwave Background (CMB), its angular power spectrum and pioneering polarization data. They are the imprints of the primordial fluctuations which initiated the growth of the large scale structures of the Universe. I will describe the results we obtained so far from temperature and polarization data, both in terms of content of the universe and of characteristics of the primordial fluctuations.
