Scientific paper

The Hubble Space Telescope opened up the exciting possibility of carrying out very deep, high-precision stellar photometry in very crowded fields such as those routinely encountered in the core of dense stellar clusters and galaxies. This capability has allowed, for example, the reliable detection of stars all the way down to the bottom of the main sequence (MS) at the centre of nearby globular clusters (GC) six or seven magnitudes below the turn-off (TO) and well into the brown dwarf substellar region of nearby starforming regions and of resolving the evolved stellar populations in nearby dwarf galaxies. Enormous progress in our understanding of the age, distance, star formation rates, and mass functions of a large sample of stellar populations has been a direct result of the last ten years of HST.
