The Cincinnati Observatory, the first public observatory in the Western Hemisphere, has one of the oldest working telescopes in the world and is known as The Birthplace of American Astronomy. This observatory is a center for astronomical education, offering programs that use its equipment for STEM support in local K-12 schools.
They offer many school programs like Field Trips and Outreach to You (which brings the observatory to you), as well as fun Scout Programs and many awesome events like Stonelick Star Gazes.
The current exhibit is The Brightest Stars: The Legacy of Cincinnati’s Women Astronomers, but you should keep updated on the official website for upcoming exhibits and exciting events.
