Edwin Powell Hubble, (1889-1953), was an American astronomer whose work revolutionized our understanding of the size and structure of the universe. In the early 1900's, many astronomers believed that all stars and other celestial objects were part of the Milky Way, the galaxy that contains our solar system. In the 1920's, Hubble studied a hazy patch of the sky called the Andromeda Nebula. Hubble noticed that it contained stars resembling stars in the Milky Way but much fainter. He concluded that the stars in the nebula must be much farther from Earth than stars in our own galaxy. His work proved that the Andromeda Nebula was actually a distant galaxy separate from our own.
