In , an astronomer named Edwin Hubble made a startling observation from a mountaintop observatory in southern California. Based on his readings and calculations, he concluded that the further a galaxy is from us, the faster it appears to be receding into space.
Ultimately, his work, based on the findings of previous scientists, including Harvard Observatory "human computer" Henrietta Swan Leavitt, demonstrated a relationship between the speed of cosmic objects and their distance from Earth. The finding amounted to groundbreaking evidence that the universe is expanding.
The Great Debate: How Many Galaxies?

Hubble began his post-graduate career at southern California's Mount Wilson Observatory in , an exciting time in the field, according to Vassar College assistant professor of astronomy Ed Buie.
"There were a bunch of newly commissioned telescopes in California, and folks were starting to get involved in really ramping up their efforts as far as observing extragalactic sources, things that are beyond our galaxy," says Professor Buie.
The catch is that many stargazers weren't convinced that anything existed beyond the "island universe" of the local galaxy, then estima

Edwin Powell Hubble (November 20, – September 28, )[1] was an American astronomer. He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology.[2][3]
Hubble proved that many objects previously thought to be clouds of dust and gas and classified as "nebulae" were actually galaxies beyond the Milky Way.[4] He used the strong direct relationship between a classical Cepheid variable's luminosity and pulsation period[5][6] (discovered in by Henrietta Swan Leavitt[7]) for scaling galac
