Edwin Hubble (1889-1953) with the 48 inch Schmidt Telescope, Palomar Observatory, 1949. Hubble discovered that the degree of 'Doppler shift' observed in the light spectra from other galaxies increased in proportion to a particular galaxy's distance from Earth, a relationship that became known as Hubble's law and helped establish that the universe is expanding. | |
