The Boston Athenaeum and the American Philosophical Society presented a conversation with astrophysicist and planetary scientist Sara Seager. The program linked Seager’s research on exoplanets to the scientific legacy of David Rittenhouse, the eighteenth-century mathematician, instrument maker, and astronomer whose observations during the 1769 Transit of Venus helped make present-day planet-hunting possible. The evening covered topics including the use of instrumentation and modes of visualization for detecting distant planets and astronomical phenomena, the importance of global scientific exchange and international cooperation for establishing new theories, and reflections on humanity’s enduring fascination with the possibility of life beyond Earth.
This conversation is part of “America’s Scientific Revolutionaries,” a two-year initiative funded by the Richard Lounsbery Foundation highlighting the work of lesser-known scientists and physicians active during the Revolutionary era.
About the Speaker
Sara Seager is a Professor of Physics, Planetary Science, and Aeronautics and Astronautics at the Massachusetts Institute of Technology where she holds the Class of 1941 Professor Chair. Her ground-breaking research ranges from the foundation of exoplanet atmospheres to innovative theories about life on other worlds to development of novel space mission concepts. She was the Deputy Science Director of the NASA mission TESS; PI of the JPL-MIT CubeSat ASTERIA; and has had numerous leadership roles in concept development for space-based direct imaging missions to discover another Earth. She currently leads the Morning Star Missions to Venus to search for signs of life or life itself in the Venus clouds. Her many accolades include a MacArthur Foundation “genius” grant, the Kavli Prize in Astrophysics, and appointment as an Officer of the Order of Canada. She is the author of “The Smallest Lights in the Universe: A Memoir.” She is also a Member of the American Philosophical Society (2018) and received the Society’s Magellanic Premium Medal in 2021.
Adrianna Link is Curator of History of Science at the American Philosophical Society in Philadelphia, where she manages the Society’s collections and projects on this topic. She earned her PhD in the history of science from Johns Hopkins University, where she specialized in the history of American anthropology and the formation of anthropological archives during the mid-20th century. Her scholarship has been published in the Journal for the History of the Behavioral Sciences and Bérose, as well as in several edited volumes. She is currently finishing a book manuscript on the history of “urgent anthropology” at the Smithsonian Institution.
