Here's what Hubble is known for:
* Observational Astronomy: Hubble's primary contribution was in observing and analyzing galaxies, using powerful telescopes like the 100-inch Hooker telescope at Mount Wilson Observatory.
* Hubble's Law: He formulated Hubble's Law, which states that the farther away a galaxy is, the faster it is moving away from us. This discovery provided crucial evidence for the expanding universe theory.
* Classification of Galaxies: Hubble developed a system for classifying galaxies based on their shapes, which is still used today.
While he didn't invent a telescope, his research and discoveries revolutionized our understanding of the universe and played a crucial role in the development of modern astronomy.
