The Milky Way Galaxy
... The Shapley–Curtis debate was the first major public discussion between astronomers as to whether the Milky Way contains all the stars in the universe. Cepheid variable stars are important in determining the distance to other galaxies. Edwin Hubble proved that there are other galaxies far outside of ...
