Nature of galaxies[edit] Galactic phenomena[edit] Galactic year – duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy.[1] Galaxy formation and evolution Galaxy merger Hubble's Law Galaxy components[edit] Components of galaxies in general Active galactic nucleus Galactic bulge Galactic disc Galactic habitable zone Galactic halo Dark matter halo Galactic corona Galactic magnetic fields Galactic plane Galactic spheroid Interstellar medium Spiral arms Supermassive black hole Structure of specific galaxies Milky Way components Galactic Center Galactic quadrant Spiral arms of the Milky Way Carina–Sagittarius Arm Norma Arm Orion Arm Perseus Arm Scutum–Centaurus Arm Galactic ridge

Galactic cartography[edit] Further information: Celestial cartography Galactic coordinate system Galactic longitude Galactic latitude Galaxy rotation curve

Larger constructs composed of galaxies[edit] Galaxy groups and clusters   (list) Local Group – galaxy group that includes the Milky Way Galaxy group Galaxy cluster Supercluster   (list) Brightest cluster galaxy Fossil galaxy group Galaxy filament Intergalactic phenomena[edit] Galactic orientation Galaxy merger Andromeda–Milky Way collision Hypothetical intergalactic phenomena Intergalactic travel Intergalactic dust Intergalactic stars Void   (list)

Fields that study galaxies[edit] Astronomy Galactic astronomy – studies the Milky Way galaxy. Extragalactic astronomy – studies everything outside the Milky Way galaxy, including other galaxies. Astrophysics Cosmology Physical cosmology

Galaxy-related publications[edit] Galaxy catalogs[edit] Atlas of Peculiar Galaxies Catalogue of Galaxies and Clusters of Galaxies David Dunlap Observatory Catalogue Lyon-Meudon Extragalactic Database Morphological Catalogue of Galaxies Multiwavelength Atlas of Galaxies Principal Galaxies Catalogue Shapley-Ames Catalog Uppsala General Catalogue Vorontsov-Vel'yaminov Interacting Galaxies

Persons influential in the study of galaxies[edit] Galileo Galilei – discovered that the Milky Way is composed of a huge number of faint stars.[2][3] Edwin Hubble
