Together with Sandage, this person names the most massive and luminous variable stars in the M31 galaxy, and he used Cepheid variables to show the Andromeda spiral nebula was actually a galaxy far beyond the Milky Way.
Together with Sandage, this person names the most massive and luminous variable stars in the M31 galaxy, and he used Cepheid variables to show the Andromeda spiral nebula was actually a galaxy far beyond the Milky Way. He introduced a classification scheme for galaxies based on shape, known as his namesake tuning fork diagram. The inverse of his namesake constant is an estimate of the age of the universe, and he worked together with one-time janitor Milton Humason to formulate his namesake law, which states the redshifts of remote galaxies are proportional to their distances from Earth. For 10 points, name this American astronomer, the namesake of a notable Space Telescope.
