Short Summary
Edwin Hubble was a pioneering American astronomer whose work fundamentally changed our understanding of the universe. He is best known for discovering that the universe is expanding, which provided key evidence for the Big Bang theory. Hubble's observations of distant galaxies led to the formulation of Hubble's Law, establishing a linear relationship between a galaxy's distance and its velocity. His contributions have made him a central figure in cosmology, and his legacy endures in the field of astronomy.
Early Life & Education
Edwin Powell Hubble was born on November 20, 1889, in Marshfield, Missouri, to John Powell Hubble and Virginia Lee James. His family moved to Chicago, where he developed an early interest in science and astronomy. Hubble attended the University of Chicago, where he focused on mathematics and astronomy, earning his undergraduate degree in 1910. He furthered his studies at the University of Oxford as a Rhodes Scholar, gaining a degree in jurisprudence. Despite this diversion, he continued to pursue his passion for astronomy and returned to the field, eventually earning a Ph.D. from the University of Chicago in 1917.
Career Highlights
Hubble began his career at the Mount Wilson Observatory in California, where he had access to the most powerful telescope in the world at the time. In 1923, he made a groundbreaking discovery of individual stars in the Andromeda Nebula, proving that it was a separate galaxy outside of the Milky Way. This finding significantly expanded the known universe. In 1929, Hubble formulated Hubble's Law, demonstrating that galaxies are moving away from each other, indicating an expanding universe. His work laid the foundation for modern cosmology and influenced generations of astronomers and physicists.
Major Achievements
