Edwin Hubble
Edwin Hubble, the pioneering American astronomer, transformed humanity’s view of the cosmos. Born in 1889, he combined athletic prowess with intellectual brilliance, eventually turning from law to astronomy. At Mount Wilson Observatory, he used the Hooker Telescope to prove that galaxies extend beyond the Milky Way, vastly expanding the known universe. His most profound discovery was the observation that galaxies recede from one another, leading to the formulation of Hubble’s Law and the concept of an expanding universe. This breakthrough laid the foundation for modern cosmology and the Big Bang theory. Hubble’s legacy endures, immortalized by the Hubble Space Telescope.
“The history of astronomy is a history of receding horizons.”
