Star formation histories of resolved stellar populations: in and beyond the Local Group
The exploitation of the power and the spatial resolution of HST and new generation ground-based telescopes allows to measure with good precision the individual stars of galaxies in and beyond the Local Group. This leads to very successful studies of the star formation histories of galaxies of different morphological types. Our current knowledge of the star formation history of galaxies within 10-20 Mpc, as derived from the colour-magnitude diagrams of their resolved stellar populations, is reviewed here.
