The famous astronomer Edwin Hubble showed that ‘spiral nebulae’ were actually galaxies of stars beyond our own galaxy, the Milky Way. He devised a system of galaxy classification that is still widely used today.
These galaxy images were taken at the Mount Wilson Observatory in California and show some of the different types of spiral galaxy.
