Galaxies

Island universes of billions of stars: elegant spirals, giant ellipticals and the gloriously messy irregulars.

This part of the universe is still being built. Our crew is pouring dark matter and tightening the event horizon, so please keep a safe distance from the black hole.

Coming to this sector

  • A catalog of famous galaxies, from the Milky Way to Andromeda
  • Real telescope images with bite-sized facts
  • Size, distance and star-count comparisons that will make you feel tiny
