How many different shapes of galaxy are there?

Answer:
There are four classifications for galaxy shapes. Spiral, like our milky way, oblique, such as G 3417., a conjoined spiral, (these are fairly rare so far, that is we have seen very few of these so far), this type of galaxy forms when two spiral galaxies get close enough that the gravitational pull from each of the galaxies massive black holes, (located in the center of every galaxy), "pull" the two galaxies towards one another and the result is a spectacular collision that can last for many billions of years. The last classification is commonly known as "junk galaxies", (although there is no actual name), and it includes all other shapes that are not included in the other three classifications.
