Venture to infinity and beyond for a look at astronomy in the wizarding world. We're joined by Jane Bright, a PhD candidate in astronomy and astrophysics at the University of Arizona. Astronomy is the one subject wizards and Muggles seem to have in common. Why is it important enough to be a required subject at Hogwarts, and how is it different from the astrology that is part of Divination? Jane has some theories regarding the historical split between disciplines and the usefulness of astronomical knowledge in ritual magic. As a bonus, wizards may actually be learning some math! Astronomy is present in the wizarding world outside of the classroom as well. Dumbledore's watch, for instance, shows the movements of stars and planets, and a room in the Department of Mysteries appears to be devoted to the study of space. Magical telescopes seem old-fashioned, but wizards must be keeping up with Muggle scientific advances if they know about planets and phenomena that were discovered after wizards went into hiding.
