V.M. Slipher exposes first plates for his radial velocity study

On September 17, 1912, Vesto Melvin (V.M.) Slipher exposed the first plate on which he would later measure the first radial velocity of a “spiral nebula” — which would later become known as the Andromeda Galaxy. Using the 24-inch telescope at Lowell Observatory he followed up with more Doppler shifts, and established that large velocities, usually in recession, are a general property of the spiral nebulae. Those early redshifts measured by Slipher were not only recognized as remarkable by the community, but were later critical to the discovery of what eventually came to be called “The Expanding Universe.” That is, evidence that galaxies and nebulae are moving further away from each other and the universe itself expands.
