A Galaxy is a group of stars and solar systems. We live in the Milky Way Galaxy, a spiral Galaxy.

Many types of galaxies exist:

  • Barred Spiral, which have arms extending out of a nucleus
  • Spiral, with smooth arms extending out of a nucleus
  • Elliptical, which are shaped like spheres or ellipsoids
  • Irregular, which have no definite shape

There must be at least 100 million galaxies in the universe.
