  Some highlights are given of the IAU Symposium 334, Rediscovering our Galaxy,
held in Potsdam, in July 2017: from the first stars fossil records found in the
halo, the carbon-enhanced metal poor CEMP-no, to the cosmological simulations
presenting possible scenarios for the Milky Way formation, passing through the
chemo-dynamical models of the various components, thin and thick disks,
box/peanut bulge, halo, etc. The domain is experiencing (or will be in the near
future) huge improvements with precise and accurate stellar ages, provided by
astero-seismology, precise stellar distances and kinematics (parallaxes and
proper motions from GAIA), and the big data resulting from large surveys are
treated with deep learning algorithms.
