Edwin Hubble was an astronomer who discovered in 1929 that there was a substantial excess of galaxies with red-shifted spectra than those with blue-shifted spectra, indicating that most galaxies are moving away from the Earth. These observations support scientific models of a "Big Bang" origin of the universe. The Hubble Space Telescope is named after him.
