Edwin Hubble is best known for his groundbreaking work in observational astronomy, particularly for establishing that the universe is expanding. His observations of distant galaxies led to the formulation of Hubble's Law, which states that the farther away a galaxy is, the faster it is moving away from us. This discovery fundamentally changed our understanding of the cosmos and supported the Big Bang theory. Additionally, Hubble played a key role in classifying galaxies and contributed to the development of the field of extragalactic astronomy.
