Comets in Astrology: Past and Present

In episode 503 of The Astrology Podcast astrologer Rod Chang joins me to discuss the long and fascinating history of comets in astrology, how astrologers viewed them as omens in ancient times, and creating a new foundation for interpreting them today. While comets are a notable astronomical phenomenon and are famous in legends from ancient times as powerful omens, there has been very little discussion about their meaning or use in modern astrology. Part of the reason for this is that they appear so infrequently, are difficult to calculate, and are not included in most astrology software, which has led to them being largely overlooked by contemporary astrologers. We begin the discussion by exploring the long history of comets in astrology, noting the contrast between the Western tradition and the Chinese tradition. In the West, research into comets was set back for centuries by Aristotle's mistaken belief that they were merely atmospheric phenomena. In the Chinese tradition, however, comets were meticulously documented for thousands of years, where they were often referred to as "broom stars" that could sweep away the old government or indicate the need for reform. This eventually led to a rich history of astrological interpretation, which we are only now beginning to recover and understand. During the course of the episode we talk about what comets are from an astronomical perspective, as well as how their erratic and unpredictable nature became a key part of their astrological interpretation. Traditionally comets were interpreted as omens that signified major disruptions, the death of prominent people, and important turning points in history. Their meaning was often derived from their visual appearance, such as their color or the shape of their tail. While often viewed as negative omens that coincided with natural disasters or the death of rulers, there are also instances where they were interpreted positively. Towards the end of the episode we discuss how contemporary astrologers are now in a much better position to study comets, with new tools that allow us to calculate their positions and go back and research what was happening in the world when major comets appeared in the past. This is a large part of the focus of Rod's new book titled Comets in Astrology, where he identifies some of the most important "Great Comets" in history and documents the events that coincided with their appearance. We hope that this discussion provides a good foundation for a subject that will become an exciting new area of research in astrology in the years to come.
