What we knew before HST: globular clusters are old, dense, compact – a distinct type of stellar spheroids. Kormendy. (1985). Over 20 years the Hubble Space Telescope has revealed young massive star clusters in interacting and gas-rich galaxies.. William Herschel’s map of the Milky Way based on star counts. In the early 1800’s William Herschel, the man who discovered the planet Uranus, tried to understand the shape of the Milky Way by counting stars. He counted how many stars there were in each of dozens of different directions and then plotted the count versus direction. .
