He was an astronomer who changed the understanding of the universe by confirming that galaxies exist outside of our own Milky Way galaxy. He also helped establish that the universe is expanding.
Edwin Hubble went to Oxford University on a Rhodes scholarship, where he studied law. In 1913, Hubble was admitted to the bar, setting up a small practice in Louisville Kentucky, but it didn’t take long for Hubble to realize he wasn’t happy as a lawyer, and that his real passion was astronomy. So he studied at the Yerkes Observatory, and in 1917, received a doctorate in astronomy from the University of Chicago.
