Galaxies

The three main classifications of Galaxies are: Spiral Galaxies- Our galaxy, The Milky Way, is a spiral galaxy. A spiral galaxy looks exactly as it sounds,it's a spiral, or has a similar shape to a pinwheel. Elliptical Galaxies- These galaxies have a similar look to flattened balls. They contain billions of stars but have little gas or dust between the stars, because of this new stars cannot form in most elliptical galaxies. Elliptical galaxies have mostly old stars. Irregular Galaxies- Other galaxies are not spirals or flattened balls, but irregular. Hence the name irregular galaxies.
