Hubble, Edwin Powell


Astronomer, born in Missouri, United States (1889-1953). Author of The Observational Approach to Cosmology and The Realm of the Nebulae (1935). Hubble was the first individual to demonstrate the existence of galaxies outside of our own. He also used Vesto Slipher's redshift data to show that the degree of redshift increases with distance, thus providing evidence that the universe is expanding. He discovered the asteroid 1373 Cincinnati.
