On September 21, 2012, two astronomers using a telescope in the International Scientific Observing Network (ISON) near Kislovodsk, Russia, discovered a comet that came to be formally known as C/2012 S1 and was popularly called Comet ISON. Just a year later, two honors instructors in Wichita, Kansas, found themselves teaching a course on Comet ISON that came to be formally known as Fire in the Sky and was popularly referred to as "the comet course." In this article, the authors discuss preliminary considerations for the course, sample topics and approach, and major assignments for the course.
