Velocity-Distance Relation among Extra-Galactic Nebulae. Figure 1: Radial velocities, corrected for solar motion, are plotted against distances estimated from involved stars and mean luminosities of nebulae in a cluster.

The black discs and full line represent the solution for solar motion using the nebulae individually; the circles and broken. Methods of determining distances of extra-galactic nebulae are discussed, and the mean absolute magnitude is revised on the basis of (i) Shapley's revision of the zero- point of the period-luiuinosity curve for Cepheids, and (2) more extensive observations of stars involved in nebulae.

Distances of extra-galactic nebulae depend ultimately upon the appli-cation of absolute-luminosity criteria to involved stars whose types can be recognized. These include, among others, Cepheid variables, novae, andbluestars involvedin emission nebulosity.

Numericalvalues depend upon the zero point of the period-luminosity relation among Cepheids. The publication of Edwin Hubble's article “A relation between distance and radial velocity among extra-galactic nebulae” marked a turning point in understanding the universe. In this brief report, Hubble laid out the evidence for one of the great discoveries in 20th century science: the expanding universe.

• The classification of extragalactic nebulae • The discovery of a linear relationship between distance and velocity for extra-galactic nebulae, providing the first evidence for the expanding universe • The brightness profile of galaxies The discoveries above are well-known to.

It was Edwin Hubble’s seminal PNAS paper, “A relation between distance and radial velocity among extra-galactic nebulae”, that led to a turning point in our understanding of the universe. In his short paper, Hubble presented the observational evidence for one of science’s greatest discoveries—the expanding universe.

Hubble wrote Shapley that he had held the paper for more than a year, wanting more data. Two years later, he had the additional data, and published “The Velocity-Distance Relation among Extra-Galactic Nebulae,” coauthored with Milt Humason, which included measurements of another fifty nebulae.

Among the astronomers present at the IAU meeting, who might have been interested in a possible velocity-distance relationship for galaxies, were de Sitter, Hubble, Lemaître, Lundmark, Shapley and Smart. The first tentative steps toward the discovery of the velocity-distance relationship were made by Wirtz (, ) and Lundmark ().Velocity-Distance Relation among Extra-Galactic Nebulae.

Radial velocities, corrected for solar motion, are plotted against distances estimated from involved stars and mean luminosities of nebulae in a cluster. The black discs and full line represent the solution for solar motion using the nebulae individually; the circles.This was the first noted cluster of "nebulae" that would become galaxies.

The first redshifts to galaxies in the cluster were measured in the s. Galaxies were not identified as such until the s. The distance to the Virgo Cluster would have to wait until the s. Mly represents millions of light-years, a measure of distance.
