The findings of this person resolved the Shapley-Curtis debate, and he discovered the asteroid now known as 1373 Cincinnati. This person's name is associated with NGC 2261, a variable nebula he observed when he became the first person to look through the Hale Telescope. His tuning-fork diagram separates spiral from barred spiral galaxies, and he showed that Andromeda was not a nebula, but a separate galaxy outside the Milky Way. An approximate age of the universe is given by the inverse of this man's namesake constant, which also appears in his law stating that the velocity of objects receding from the Earth is proportional to their distance; a fact he established by observing the red- shift of galaxies. Famous for proving that the universe is expanding, name this man whose model of the cosmos con- tinues to be supported by the observations of the space telescope named for him.
