What is a Galaxy?

• Galaxy A giant structure that contains hundreds
  of billions of stars bound together by gravity.
• Spiral Galaxy A galaxy whose arms curve outward
  in a pinwheel pattern. Contains solar systems and
  nebulae (gas, new stars, and dust).
• Irregular Galaxy A galaxy that does not have a
  regular shape. They do not fit in another class.
  
• Elliptical Galaxy A galaxy shaped like a
  flattened ball, containing only old stars, with
  bright centers and very little dust/gas
