This man incorrectly found Andromeda to be approximately one million light-years away. Later work led him to declare a redshift law named after him, though it was first proposed by Georges LemaÃ®tre. His "tuning fork" classifies galaxies based on appearance. The reciprocal of his namesake constant is the approximate age of the universe; that constant is commonly given in units of kilometers per second per megaparsec. For 10 points, name this American astronomer who postulated the expansion of the universe, the namesake of an orbiting telescope.
