This tutorial begins with a description of Hubble's discovery that other galaxies exist besides the Milky Way and how these galaxies are classified. Hubble's classification categorizes galaxies as either spiral, elliptical, or irregular. Under these topics there is a link that gives information about the structure, components, classification system, diameter, and the average number of stars for each galaxy type. The next section talks about the different ways that galaxies can interact, collide, or merge. The tutorial ends with a short quiz.
