astronomy. how did galaxies get their name
There is no universal naming convention for galaxies, as they are mostly catalogued before it is established whether the object is or isn't a galaxy. Mostly they are identified by their celestial coordinates together with the name of the observing project (HUDF, SDSS, 3C, CFHQS, NGC/IC, etc.).his is a general list of galaxies, for more specific lists, see lists of galaxies. Size (left) and distance (right) of a few well-known galaxies put to scale. This is an incomplete list that may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.
