What Is a Galaxy? A Galaxy is a bound of gas, dust, planets moons and Suns. Galaxies and Earth ( our Galaxy, the Milky Way) were all made from a miracle called the Big Bang. The Big Bang made spiral or oval Galaxies which over time changed in shape and size. Then planets and stars evolved inside them. http://en.wikipedia.org/wiki/Galaxy
How Many Galaxies Are There? Scientists estimate there areapproximately 200 too 300 billion stars in the Milky Way but a German telescope computer estimated 500 billion+ stars. Scientists recommend there is a galaxy out there for every star so any of those stars could be a galaxy. http://www.universetoday.com/30305/how-many-galaxies-in-the-universe/
