The 28 pages that link to Galaxy, each with the reason it gives.

• Galaxy clusterBroader topic: A galaxy is a constituent object within a cluster, not a cluster-scale structure.

• Supermassive black holeNarrower topic: Most known supermassive black holes occupy the central regions of galaxies.

• Open clusterNarrower topic: Open clusters are small stellar systems residing within galaxies, especially their disks.

• Hubble sequenceNarrower topic: The sequence sorts galaxies according to their observed forms.

• Galactic bulgeNarrower topic: The bulge is one structural component within a galaxy.

• Sloan Digital Sky SurveyNarrower topic: Galaxies make up a major population mapped and classified by SDSS.

• Coma ClusterNarrower topic: The cluster's visible members are galaxies, including the giant ellipticals near its center.

• Galaxy groupBroader topic: Each group is assembled from galaxies such as the Milky Way.

• Galaxy interactionNarrower topic: Interactions act on whole galaxies and their extended matter distributions.

• Messier catalogNarrower topic: Its entries include nearby galaxies such as Andromeda and the Whirlpool Galaxy.

• NebulaCompared with: Early telescopes blurred the distinction between some galaxies and nebulae.

• Irregular galaxyNarrower topic: Irregular galaxies are one structural class of these large stellar systems.

• Shapley SuperclusterNarrower topic: Galaxies are the luminous members grouped into the clusters that compose the supercluster.

• Solar massNarrower topic: Galaxies contain stellar populations whose total mass is often stated in solar masses.

• Whirlpool GalaxyNarrower topic: The Whirlpool’s spiral disk and companion belong to the broader class of galaxies.

• Nuclear star clusterNarrower topic: The cluster is a compact component of its host galaxy.

• Cartwheel GalaxyNarrower topic: The Cartwheel is a galaxy whose components were reshaped by a collision.

• Messier objectBroader topic: Messier entries include nearby galaxies such as Andromeda.

• Astronomical objectBroader topic: Galaxies show that astronomical objects can be systems containing many smaller bodies.

• Messier 81Narrower topic: M81 is one member of this wider class of cosmic systems.

• Low surface brightness galaxyNarrower topic: Low surface brightness describes a structural and observational class of galaxies.

• NASA/IPAC Extragalactic DatabaseBroader topic: Galaxies are a central class of extragalactic objects represented in NED.

• Extragalactic astronomyNarrower topic: Galaxies are the principal objects whose populations and properties extragalactic astronomy investigates.

• TucanaNarrower topic: The Small Magellanic Cloud and Tucana’s dwarf galaxies are nearby galaxy systems.

• Galaxy groups and clustersBroader topic: Galaxies are the visible members whose motions trace the system’s gravity.

• Uppsala General CatalogueNarrower topic: The catalog’s entries are galaxies, grouped and described as individual systems.
