galaxies
Vast stellar systems
Galaxies is the plural of galaxy, a massive system of stars, gas, dust, and dark matter bound together by gravity.
The Milky Way is our home galaxy; billions more exist across the observable universe.
Galaxy comes from a Greek word meaning milk, referring to the milky appearance of stars across the night sky.
Figuratively, a galaxy of something means a brilliant gathering: a galaxy of Hollywood stars.
