title: The Milky Way seen by the Gaia mission. 
abstract: The Gaia ESA mission is observing since 2014 more than a billion stars of the Milky Way. It measures their positions, distances, motions and physical properties with an unprecedented accuracy. Gaia therefore brings an enormous amount of new information on our Milky Way, allowing an extremely detailed study of its three dimensional structure and kinematic, its origin and evolution. I will present what kind of observation Gaia brings us and how they are in the process of revolutionizing our knowledge of the Milky Way.
