The 14 pages that link to Harlow Shapley, each with the reason it gives.

• Edwin HubbleCompared with: Shapley argued that spiral nebulae lay within the Milky Way, opposing Hubble’s extragalactic interpretation.

• Cepheid variableRelated: His Cepheid-based distance estimates shifted the Sun away from the center of the Galaxy.

• Cecilia Payne-GaposchkinRelated: As observatory director, he supported Payne's appointment and research career.

• Henrietta Swan LeavittRelated: Shapley applied Leavitt’s relation to measure distances within the Milky Way.

• Mount Wilson ObservatoryRelated: His Mount Wilson research displaced the Sun from the galaxy’s center.

• Harvard College ObservatoryRelated: His Harvard work placed the Sun away from the center of the Galaxy.

• Vesto SlipherRelated: Shapley used Slipher’s observations in arguments about the scale and nature of spiral nebulae.

• Shapley SuperclusterRelated: The supercluster bears his name because he drew attention to the concentration of galaxies in Centaurus.

• Walter BaadeRelated: His Cepheid calibration belonged to the distance-scale tradition Baade’s work revised.

• Classical Cepheid variableRelated: His Cepheid-based work expanded estimates of the Milky Way beyond earlier scales.

• Zone of AvoidanceRelated: Shapley drew attention to the shortage of known external galaxies along the Galactic plane.

• Extragalactic astronomyRelated: His work clarified the Milky Way’s scale before the external-galaxy debate was settled.

• Messier 15Related: His work helped establish globular clusters such as Messier 15 as tracers of the Galaxy's structure.

• Immanuel VelikovskyRelated: He opposed publication of Velikovsky’s claims through his influence in academic science.
