Edwin Hubble was a pioneering astronomer who made groundbreaking contributions to our understanding of the universe:
* The Expanding Universe: Hubble's most famous discovery was that the universe is expanding. He observed that galaxies are moving away from each other at a rate proportional to their distance. This observation, now known as Hubble's Law, formed the basis for the Big Bang theory.
* Classifying Galaxies: Hubble developed a system for classifying galaxies based on their shape and structure. This classification system, known as the Hubble Sequence, is still used by astronomers today.
* The Size of the Universe: Hubble determined the distance to galaxies outside the Milky Way, dramatically increasing our understanding of the scale of the universe.
