Explanation:
Detailed explanation-1: -Galaxies are classified by shape. There are three general types: elliptical, spiral, and irregular. Perhaps the most familiar kind of galaxy are spiral galaxies. They have a distinctive shape with spiral arms in a relatively flat disk and a central “bulge".
Detailed explanation-2: -Yet over the past several billion years, many galaxies in clusters have changed from spiral to a smooth, or “lenticular, ‘’ disk shape. Theory suggests that galaxies can change from spiral to lenticular when two of them collide in slow motion interactions.
