When was space discovered: On October 1923, using the Hooker telescope, Edwin spotted what he thought was a Nova Star. After he examined photographs of that same spot he realized that it was a particular kind of variable star. In 1926 he made a startling find, most galaxies seemed to be receding us with velocities that increased in proportion to their distance from us. He tried to win a Nobel Prize in the late 1940's. He died in 1953.
