Often called a "pioneer of the distant stars", astronomer Edwin Hubble (1889–1953) played a pivotal role in deciphering the vast and complex nature of the universe. His meticulous studies of spiral nebulae proved the existence of galaxies other than our own Milky Way.

6 days ago · A century ago, Edwin Hubble determined that the Andromeda nebula was nearly a million light years away, proving it was not part of the Milky Way and confirming the existence of other galaxies.

Jan 24, 2025 · Hubble wrote about his discovery to Harlow Shapley, who had argued that the Milky Way encompassed the entire universe. “Here is the letter that destroyed my universe,” Shapley remarked .

Jan 16, 2025 · A century ago, Edwin Hubble first established that this so-called “spiral nebula” was actually very far outside our own Milky Way galaxy — at a distance of approximately 2.5 million light-years or roughly 25 Milky Way diameters. Prior to that, astronomers had long thought that the Milky way encompassed the entire universe.

Dec 26, 2024 · At Mount Wilson, Hubble initially studied reflection nebulae within the Milky Way. However, soon he returned to the problem of the so-called spiral nebulae, objects he had investigated for his doctorate. The status of the spirals (as …

Oct 4, 2023 · Like the Hubble Space Telescope, Edwin Hubble’s discoveries transformed the frontier of scientific knowledge. His work took us beyond the Milky Way and placed us in an ever-expanding universe with a myriad of galaxies beyond our own.

Feb 22, 2024 · In 1924, Edwin Hubble found proof that the Milky Way isn’t the only galaxy in the Universe.

Aug 12, 2012 · Hubble soon met his greatest scientific rival, Harlow Shapley, who had made his reputation measuring the size of the Milky Way, our own galaxy. Shapley, like most astronomers of the time, thought that the Milky Way was the entire Universe.
