What did Edwin Hubble discover while using the Mount Wilson telescope?
Mount Wilson Observatory is a Los Angeles-area facility with several telescopes open to astronomers and the public. Perhaps its most notable discovery came in the 1920s, when Edwin Hubble used photographic plates from the 100-inch telescope to discover that the Andromeda Galaxy is a galaxy in its own right.
What did Edwin Hubble discover about galaxies at Mt Wilson Observatory in 1929?
With two discoveries, announced in January 1925 and January 1929, astronomer Edwin Hubble radically changed our idea of the cosmos, showing first that the universe was much larger than previously thought, and second that it is expanding, getting larger and larger all the time.
What was Hubble measuring at the Mr Wilson Observatory?
Using observations he made in 1922–1923, Hubble was able to prove that the Universe extends beyond the Milky Way galaxy, and that several nebulae were millions of light-years away….100-inch Hooker telescope.

| 1923 | Edwin Hubble conclusively proves the Andromeda nebula to be external to the Milky Way galaxy |
What did Edwin Hubble discover in 1924 and why was that important?
On December 30, 1924, Hubble discovered the existence of other galaxies using the most advanced telescope in the world. Not long ago, there were no galaxies far, far away. In fact, less than a century ago, many scientists believed there was just one galaxy, the Milky Way.
What was Edwin Hubble known for?
Edwin Hubble, in full Edwin Powell Hubble, (born November 20, 1889, Marshfield, Missouri, U.S.—died September 28, 1953, San Marino, California), American astronomer who played a crucial role in establishing the field of extragalactic astronomy and is generally regarded as the leading observational cosmologist of the …
What was Edwin Hubble most important discovery?
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 understanding of the universe and our place within it.
What was Edwin Hubble famous for?
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.
Why is Edwin Hubble’s discovery so important?
Astronomer Edwin Hubble revolutionized the field of astrophysics. His research helped prove that the universe is expanding, and he created a classification system for galaxies that has been used for several decades.
Did Edwin Hubble invent the Hubble telescope?
Hubble Space Telescope Facts. NASA named the world’s first space-based optical telescope after American astronomer Edwin P. Hubble (1889 — 1953). Hubble confirmed an “expanding” universe, which provided the foundation for the big-bang theory.
Why was Edwin Hubble important?
How many galaxies did Edwin Hubble discover?
46 galaxies
But the most astonishing discovery Hubble made resulted from his study of the spectra of 46 galaxies, and in particular of the Doppler velocities of those galaxies relative to our own Milky Way galaxy.
What did Edwin Hubble discover with his 100-inch telescope?
Mount Wilson’s 100-inch telescope set the stage for our understanding of cosmic distances to galaxies. Edwin Hubble was using the facility in the 1920s when he discovered something interesting in photographic plates of Andromeda. At the time, Andromeda was believed to be a spiral nebula — a vast collection of gas in the cosmos.
What is Mount Wilson Observatory used for?
Mount Wilson Observatory is a Los Angeles-area facility with several telescopes open to astronomers and the public. Located on a mountaintop at an altitude of more than 5,000 feet (1,524 meters), the observatory has been a useful location over the decades for measurements on stars,…
What is the largest telescope ever built on Mount Wilson?
The photos really capture the effort that went into building this famous telescope.) With the completion of the 60-inch telescope in 1908, Mount Wilson became the home of the largest astronomical instrument in the world. But in typical fashion, George Ellery Hale was already making plans for a much larger instrument, one of unheard-of dimensions.
Who donated the telescope to the Yerkes Observatory?
The telescope was donated to Yerkes Observatory by Helen Snow of Chicago. George Ellery Hale, then director of Yerkes, had the telescope brought to Mount Wilson to put it into service as a proper scientific instrument. Its 24-inch (61 cm) primary mirror with a 60-foot (18 m) focal length, coupled with a spectrograph,…
