Richard D. Schwartz Observatory (RSO) is UMSL's on-campus astronomical facility on North Campus, dedicated to research and public education in astronomy through the Department of Mathematics, Physics, Astronomy and Statistics. Open to the public during scheduled open house nights (typically March–October) for free stargazing of the moon, planets, stars, galaxies, and more, the observatory is a welcoming spot for students, families, and the St. Louis community to explore the night sky.
