Astronomy and its related sciences (including space and planetary sciences, cosmology, astrophysics, astrobiology, and others) have a rich history with connections that span centuries, cultures, and disciplinary boundaries. This working group explores the many ways in which astronomical knowledge, interests, and ideas have interacted with human history, exploring impacts and influences both in and beyond the scientific/scholarly community. We welcome contributions across a variety of historical time periods and from varied disciplinary and methodological approaches.

Narratives on the Marginalization of Astrology
For our first discussion, we will be looking at two articles on the marginalization of astrology. When, how, and why did astrology go from being considered a viable knowledge system to a pseudo-science? Recent work has revisited this question, providing an overview of different factors for astrology’s marginalization and showing how explanations have moved from an emphasis on intellectual factors to social/institutional influences and back again. This will be the first meeting of our working group, so please come prepared to briefly introduce yourself and what brings you to the group!
