I've spent many an hour at the David Dunlap Observatory in Richmond Hill.
It's a wonderful space, and when I was there I use to think a lot about one of the great astronomers who did her
research on globular clusters
there with the big 74" telescope, when it was owned by the University of Toronto several years ago.
None other than Helen Sawyer Hogg of course.
And I just read a wonderful article that I thought you too might enjoy.
Here is the link to the article.
