The Planck satellite has recently delivered the most accurate map of the cosmic microwave background radiation. This picture provides precious infromation about the Universe at its earliest stages, more than 13 billion years ago, and on its subsequent evolution. I will review the most relevant lessons learnt from Planck as well as from a wealth of other present and future observational probes, both in space and on Earth. The impact of cosmology and astroparticle physics on our understanding of some of the main open questions of fundamental physics, such as the nature of Dark Matter and the origin of the present accelerated expansion of the Universe, will be highlighted.
