Extra-galactic nebulae

Edwin Hubble's work on extra-galactic nebulae revolutionized our understanding of the universe. He meticulously observed these distant celestial objects leading to the groundbreaking realization that they were not merely part of our Milky Way galaxy but rather independent galaxies themselves. This discovery expanded the known universe dramatically suggesting that it was far larger and more complex than previously thought. Hubble's observations laid the foundation for modern cosmology providing critical evidence for the existence of galaxies beyond our own and challenging the prevailing notions of a static universe.***Hubble's findings also contributed to the formulation of Hubble's Law which describes the relationship between the distance of galaxies and their redshift indicating that the universe is expanding. This pivotal insight not only transformed astronomical science but also sparked further research into the origins and evolution of the cosmos. Hubble's legacy endures as a cornerstone of astrophysics inspiring generations of astronomers to explore the vastness of space and unravel the mysteries of the universe beyond our own galaxy.
