Listen to the podcast to hear the full conversation.
Historian Chrissie Senecal joined The Spark to explore how people throughout history have understood comets and meteors, especially long before modern science could explain what was happening in the sky. With the Geminid meteor shower lighting up December skies and holiday traditions top of mind, the conversation tied celestial events to seasonal stories, including legends surrounding the Star of Bethlehem. Senecal walked through what comets actually are, where they come from, and how ancient observers first recognized them as something different from stars or planets—often seeing them as omens or messages rather than natural objects.
The discussion spanned cultures and centuries, from early written records of comets to religious and astrological interpretations found across the world. Senecal also explained how Renaissance art reflected these beliefs, including Giotto’s “Adoration of the Magi,” which famously depicts the Star of Bethlehem as a comet. The conversation wrapped with a look at how scientific understanding of comets has evolved over the last century and why, even today, some people still attach special meaning to these rare and dramatic sights in the night sky.
