The first billion years after the Big Bang are characterized by a complex interplay between formation of the first stars (metal-free) and the first galaxies (metal-enriched). These first light sources start illuminating the Universe and ionizing hydrogen atoms, defining the initial conditions for the formation of today’s stars, galaxies and black holes. The Wide Field Camera 3 on board the Hubble Space Telescope is providing us with a new view on this epoch, previously accessible only through numerical simulations. I will present an overview of the most recent results in the field, focusing on the comparison of Hubble’s observations at redshift z>6 from the HUDF and BoRG surveys with theoretical/numerical models of galaxy formation and evolution.
