Astronomy After Hours at the MOS Observatory

Tucked away on the roof of the Museum's parking garage, the Gilliland Observatory is a wonderful resource for our starry-eyed public. On clear nights, you can view stars, planets, the Moon, and other astronomical phenomena. On cloudy nights, tour the inside of the Observatory, and participate in astronomy-related activities run by our knowledgeable staff. Astronomy After Hours is the perfect place to kick off your weekend with your family.
