Special Events

FOSAA currently sponsors two special events per year that feature an exclusive show in the spectacular Arne Slettebak Planetarium and several short talks by Ohio State researchers, who will describe recent discoveries at the frontiers of their fields, at a level accessible to all. Following these presentations, an informal lunch with Ohio State faculty, postdoctoral researchers, and​ students will give you the chance to ask all of your questions about planets, stars, galaxies, and the universe, and to learn more about astronomy and astrophysics research at Ohio State.
