The existence of other galaxies and red shift was actually first discovered by the American astronomer Vesto Slipher.

A third category was added in 1912 when Vesto Slipher showed that the spectrum of the nebula that surrounded the star Merope matched the spectra of the Pleiades open cluster.

As already Vesto Slipher in 1912, Wirtz in 1918 observed a systematic redshift of nebulae, which was difficult to interpret in terms of a cosmological model in which the Universe is filled more or less uniformly with stars and nebulae.

His brother Earl C. Slipher was also an astronomer and a director at the Lowell Observatory.

Edwin Hubble was generally incorrectly credited with discovering the redshift of galaxies ; these measurements and their significance were understood before 1917 by James Edward Keeler ( Lick & Allegheny ), Vesto Melvin Slipher ( Lowell ), and William Wallace Campbell ( Lick ) at other observatories.

Earl Charles Slipher ( March 25, 1883 – August 7, 1964 ) was an American astronomer.

He was the brother of astronomer Vesto Slipher.

Slipher was born in Mulberry, Indiana.

In 1913, when Vesto Slipher registered his spectroscopy study of the sky, the Crab nebula was again one of the first objects to be studied.

* The crater Slipher on the Moon is named after Earl and Vesto Slipher, as is the crater Slipher on Mars and the asteroid 1766 Slipher, discovered September 7, 1962, by the Indiana Asteroid Program.

However, Slipher discovered that the spiral nebulae had high red shifts, indicating that they were moving away at rate higher than the Milky Way's escape velocity.

In 1929 the observatory's director, Vesto Melvin Slipher, summarily handed the job of locating the planet to Clyde Tombaugh, a 22-year-old Kansas farm boy who had only just arrived at the Lowell Observatory after Slipher had been impressed by a sample of his astronomical drawings.

In 1912 Vesto Slipher measured the first Doppler shift of a " spiral nebula " ( spiral nebula is the obsolete term for spiral galaxies ), and soon discovered that almost all such nebulae were receding from Earth.

This allowed him to estimate distances to galaxies whose redshifts had already been measured, mostly by Slipher.

In the 1910s, Vesto Slipher ( and later Carl Wilhelm Wirtz ) interpreted the red shift of spiral nebulae as a Doppler shift that indicated they were receding from Earth.

Using the data collected by Vesto Slipher and his ( Hubble's ) assistant Milton Humason ( a former mule-driver and janitor ), Hubble and Humason found a direct relationship between a galaxy's distance and its relative speed away from the solar system.

Hubble supported the Doppler shift interpretation of the observed redshift that had been proposed earlier by Vesto Slipher, and that led to the theory of the metric expansion of space.

In 1912, Vesto Slipher made spectrographic studies of the brightest spiral nebulae to determine if they were made from chemicals that would be expected in a planetary system.

Slipher and Edwin Hubble continued to collect the spectra from many diffuse nebulae, finding 29 that showed emission spectra and 33 had the continuous spectra of star light.

Upon confirmation, Tombaugh walked into Slipher's office and declared, " Doctor Slipher, I have found your Planet X.

Beginning with observations in 1912, Vesto Slipher discovered that most spiral nebulae had considerable redshifts.

Slipher first reports on his measurement in the inaugural volume of the Lowell Observatory Bulletin.

" Slipher reported the velocities for 15 spiral nebulae spread across the entire celestial sphere, all but three having observable " positive " ( that is recessional ) velocities.
