The recent solar eclipse transfixed the world. People in the path of totality marveled at the corona and how the air temperature dropped briefly and, in some parts of the country, the cicadas began to sing as if it were night. But the eclipse also offers a world of possibilities for scientific discovery. Jay Pasachoff, Field Memorial Professor of Astronomy at Williams College, joins us at the Arthur C. Clarke Center for Human Imagination to discuss his observations of eclipses—66 solar eclipses, including 34 total solar eclipses—and the NSF and National Geographic supported discoveries these have yielded. Dozens of cameras, including a pair of frame-transfer CCDs, were trained on the corona to isolate the specific emissions of 13-times-ionized iron (“the coronal green line”) and 9-times-ionized iron (“the coronal red line”) at high cadence, to attempt to distinguish among models for how the corona is heated to millions of degrees. Dr. Pasachoff will discuss this work and plans for future total, partial, and annular eclipse observations over the next few years, including the 2023 and 2024 American eclipses.
