The article mentions the Lowell Observatory in Flagstaff. (Oh, the view of the stars from northern Arizona/southern Utah. It’s an amazing show.) That is one of the oldest observatories in the world, just a few years old when this article was written. Almost three decades after this article was written, it was the location of the discovery of Pluto: a feat more important to those of us to whom it was (and may always be) one of the nine planets, than to our children, who just have eight.
