Edwin Powell Hubble, 1889–1953, American astronomer, b. Marshfield, Mo. He did research (1914–17) at Yerkes Observatory, and joined (1919) the staff of Mt. Wilson Observatory, Pasadena, Calif., of which he became director. Building on V. M. Slipher's discovery that galaxies had strong shifts to the red end of their spectra, Hubble used the stars known as Cepheid variables in nearby galaxies to demonstrate that they lie far beyond the Milkygenerates.
