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.

3 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.

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.

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 …

Nov 24, 2024 · Until 100 years ago, many astronomers believed the Milky Way was the only galaxy in the universe. Edwin Hubble – for whom the Hubble telescope was named – proved otherwise 100 years ago...

Edwin Hubble, for whom the Hubble Space Telescope is named, was one of the leading astronomers of the twentieth century. His discovery in the 1920s that countless galaxies exist beyond our own Milky Way galaxy revolutionized our …

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.
