caption: The image shows a room with a desk and a chair in it, surrounded by bookshelves filled with books, papers, pens, and other objects on the tables. There is a fire extinguisher on the floor and a glass window in the background, through which we can see trees and the sky. On the left side of the image, there is a light hanging from the ceiling, and on the right side, there are cupboards with books and other items. This room is part of the Smoky Mountain Observatory.
