Dr. Marilina Cesario’s exhibit explores Medieval visions of modern science before and after Halley

Before and After Halley: Medieval Visions of Modern Science

Before and After Halley explores, for the first time, how medieval records of comets can be used to test the theory that our solar system may include an additional, undiscovered planet: Planet Nine. Combining the skills of a medievalist and an astronomer, this exhibit challenges the assumption that early medieval scientific thought was simple and undeserving of serious scientific investigation.

Marilina Cesario is Senior Lecturer in the Earliest Writings in English and Historical Linguistics at Queen’s University Belfast.
