A look at star clusters; how all stars within them are formed from the same material and are approximately the same age; a look at the two kinds of clusters – "open clusters" which are young and exist in the spiral arms of the galaxy, and "globular clusters" which are old and exist in the outskirts of the galaxy and possibly as old as the universe itself.
