Description: Explore how observations of the night sky have transformed our understanding of gravity, planetary motion, and the universe. This one-hour Adult Lifelong Learning course will trace the development of our understanding of gravity through the work of Copernicus, Kepler, and Newton before exploring modern cosmology, including how the universe began and its structure on the largest scales. The program will also bring the focus closer to home with solar observation, weather permitting, offering a chance to observe sunspots and learn about space weather. The course is led by Professor Chris Orban, a physics professor at The Ohio State University’s Marion campus and a member of the university’s Center for Cosmology and Astro-Particle Physics. Registration and payment are required; stop by the Marion Public Library’s main desk for more information.
