Edwin Hubble, was an American astronomer who has had an enormous impact on science, often compared to Isaac Newton and Galileo. Hubble has helped change our thoughts and perception of the universe in two important ways. First, Hubble confirmed the existence of other galaxies other than the Milky Way, during a time when many people thought the Milky Way was the entire universe. Secondly, with the help of other astronomers, he confirmed that the universe was expanding at a constant rate by developing a mathematical concept to back up this statement, now known as Hubble’s Law.
Born on November 20, 1889, in Marshfield, Missouri, Edwin Powell Hubble was the third of seven children. Hubble spent his early childhood in Missouri with his father, John P. Hubble, and his mother, Virginia Lee James Hubble. In 1895, Edwin entered grade school.
