The measure of the cosmic microwave background (CMB) anisotropies is a powerful tool to improve our understanding of the universe and of its evolution. Launched in May 2009, the Planck satellite is a third-generation mission aimed at the unprecedented measurement of these anisotropies (both in temperature and polarisation). This talk is based on (some of) the Planck results released in April 2013. After introducing the mission and important aspects of the data processing, I will first focus on some of the Galactic science that can be achieved using the Planck data. In a second part, I will present CMB-related studies (CMB power spectrum and CMB lensing analyses, galaxy clusters detected via the Sunyaev Zeldovich effect) and focus on the cosmological results in terms of the Lambda-CDM concordance model and its extensions.
