Noun
- a collection of billions of stars, galactic dust, black holes, etc. of which there are billions in the known universe. They usually form spiral or elliptical shapes likely due to a central gravity well (i.e. supermassive black hole), but some form irregular shapes (especially if they are broken away from another galaxy).
