INSTRUCTOR:

So this week, you need to think back to those beautiful, Messier object images that you took using COAST back in week four. Whether you realised it or not, the image that you took, if it was a nebula, was a beautiful cloud of gas and dust that can represent either the very beginning or the very end of a star's life.

This week, we're going to be looking through that entire process of stellar evolution from a cloud of gas and dust right at the beginning through the star's life cycle, its expansion, its contraction, and then finally, possibly, to an explosion producing yet another cloud of gas and dust at the other end. So as we study our way through this process, make sure that you keep that image that you took using COAST in mind.
