What is Extragalactic astronomy?
[[Image:Hubble deep field.jpg|thumb|right|300px|Deep space image from the [[Hubble Space Telescope]]]] '''Extragalactic astronomy''' is [[astronomy]] about objects outside our [[Milky Way]] galaxy.<ref>{{cite web|url=https://www.as.arizona.edu/extragalactic-astronomy|title=Extragalactic astronomy|work=arizona.edu|accessdate=10 June 2015}}</ref> It is the study of everything that is not covered in [[galactic astronomy]]: the study of objects in our galaxy. Because of improvements in technology, we can see distant objects in more detail. Two versions of extragalactic astronomy are: near-extragalactic astronomy (the study of [[galaxies]] in our [[Local Group]]) and far-extragalactic astronomy (the study of objects outside our Local Group). Pages on extragalactic astronomy include: * [[Galaxy group]] * [[Galaxy cluster]] * [[Supercluster]] * [[Quasar]]s * [[Supernova]]e * [[Observable universe]] == References == {{reflist}} {{-}} {{sci-stub}} [[Category:Astronomy]]
