Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer who profoundly changed the understanding of the universe by confirming the existence of galaxies other than the Milky Way - our own galaxy. He also considered the idea that the degree of "Doppler shift" (specifically "redshift") observed in the light spectra from other galaxies increased in proportion to a particular galaxy's distance from Earth. This relationship became known as Hubble's law. The Doppler shift interpretation of the observed redshift had been proposed earlier by Vesto Slipher, whose data Hubble used.

Edwin Hubble himself, however, doubted the interpretation of this data, which lead to the theory of the Metric expansion of space.
