Is it an Sa Sb or Sc? Although it is well accepted that the Milky Way is a spiral galaxy, there is still some contention over what class of spiral it is. Since we are stuck in the middle of it and it is often difficult to get accurate distance to astronomical objects, getting a good 3-D picture has been difficult. If we could only get a view from outside…..! Anyway this means that the answer to your question is not known. We’re not even sure if the Milky Way has a bar or not. I hope that that will satisfy the 9th graders!
