Hello and welcome to this week’s cosmic adventure to learn the ways in which astrology and astronomy differ – and to examine how the many constellations that light up our evening sky received their names. Whether you gaze up into the night sky seeking answers or only seeking wonder, learning about the differences between these two will add a whole new layer to your stargazing experience.
One reason why people can easily confuse astronomy with astrology is that each field is attracted to the same thing: the sky. However, once we get past the fact that they’re both interested in the universe, they are worlds apart. Astronomy is a science; it involves the study of stars, planets, galaxies, etc., using observation, math and physics to identify and describe what exists in the universe — from black holes to the cosmic microwave background radiation. Astrology, on the other hand, is a traditional approach that interprets the movements and locations of celestial objects as having a meaningful influence on the lives of individuals, as well as their personalities. Astrology creates a poetic story about how the stars determine or direct individual destiny or temperament by using horoscopes and zodiac signs. In contrast to astronomy, which requires verifiable empirical evidence and repeatable data, astrology uses symbolic associations and the collective wisdom of centuries.
Astronomy currently operates under the scientific umbrella, whereas astrology remains a means of personal or spiritual expression — regardless of whether or not one believes in its legitimacy.
Next, I want to discuss the beautiful patchwork quilt that covers the night sky: the constellations. These are groups of stars that people have perceived as forming patterns that resemble figures, animals or mythical creatures for thousands of years. Each name represents a piece of history, mythology and/or navigation.
Most of the more widely recognized constellations (e.g. Orion, Cassiopeia, Andromeda) come from Greek and Roman mythology, which were passed on through European traditions. Other constellations have their origins in ancient Babylonian star charts or the star lore of indigenous peoples all over the world. As interesting as this is, it was not until 1922 when the International Astronomical Union created the first standard list of 88 officially recognized constellations to help astronomers create a unified framework to map the night sky.
Perhaps the most compelling aspect of these star patterns is the role they’ve played as aids to navigation, seasonal markers for farmers, and as inspirations for countless campfire tales. Our night sky provides a tapestry that links science, mythology and the power of imagination.
Understanding the distinction between astrology and astronomy and the origins of the names of the constellations provide a greater appreciation for our position within the vastness of space. It encourages both the pursuit of scientific knowledge and the desire to find significance in the stars.
The next time you gaze upward, whether you’re mapping out the Milky Way or consulting your astrological chart, remember you are participating in a long-standing tradition of star-gazing.
Thanks for coming along with me on this journey to the stars! Next week, we’ll embark upon a tour of recent astronomical findings that are actually transforming the way we view the universe. Until then, keep looking to the skies and keep your mind open to the infinite number of cosmic stories waiting to be told.
