Rising Signs: The Medieval Science of Astrology, a new exhibit at the J. Paul Getty Museum in Los Angeles, takes a look at medieval manuscripts to showcase the importance of astrology to the period’s elites. Larisa Grollemond, an assistant curator at the museum, takes us through the impact of astrology on day-to-day decisions and the way it became tied up in the medieval obsession with humoral balances. Plus, we discuss how today’s astrology split from the modern science of astronomy. Rising Signs is on display at the Getty Museum through January 5, 2025. https://www.getty.edu/art/exhibitions/rising-signs/index.html  Recommended reading: How to Survive Mercury in Retrograde https://www.scientificamerican.com/article/how-to-survive-mercury-in-retrograde/  E-mail us at [email protected] if you have any questions, comments or ideas for stories we should cover!
