Andromeda and such (8)

I believe the answer is:

galaxies

(Other definitions for galaxies that I've seen before include "Collections of star systems" , "Groups of stars such as the Milky Way" , "Large independent systems of stars" , "Independent systems of stars in space" , "Lots of stars" .)

I've seen this clue in The Wall Street Journal.
