Edwin Hubble 2
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, Mussouri, 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. After grade school, Edwin went to Wheaton High School, where he excelled in both academics and sports. In 1906, Hubble graduated at the age of sixteen from Wheaton High School, two years earlier than most students. Be
Hubble's first notable achievement at Mount Wilson was made in October 1923. As stated before, he confirmed the existence of galaxies outside the Milky Way. In 1925, at a meeting of the International Astronomical Union, Hubble introduced a system for classifying galaxies. Galaxies were either "regular" or "irregular" according to this system. Also, regular galaxies were divided into either elliptical or spiral, and each of these classes could be divided again. The system used today is still based on Hubble's structure. Hubble made another huge discovery while at Mount Wilson. He discovered a correlation between the velocities of galaxies and distance, and came up with a mathematical concept which is now know as Hubble's Law. It states that the farther away a galaxy is from us, the faster it is moving away from us. Hubble didn't actually discover that the universe is expanding, he just put a theory together that explained it better. Today, Hubble's Law is part of the big-bang theory of the creation of the universe. During the time period tha
