Mount Cuba Astronomical Observatory, Astronomical observatory in Greenville, Delaware, United States.
Mount Cuba Astronomical Observatory is a research and teaching facility in Greenville that houses multiple telescopes for professional and educational use. The site also features a lecture room, library, and digital planetarium to support learning activities.
The Delaware Astronomical Society established this as their primary meeting place and research hub. This partnership shaped the observatory into a working center for both scientists and students.
The observatory welcomes local school groups and community organizations to learn about the sky through talks and hands-on viewing sessions. Visitors experience how people connect with astronomy in a shared setting where learning happens together.
The facility holds monthly meetings on the third Tuesday of each month when the space is open for visits. Plan your trip for clear nights away from bright city lights to get the most out of telescope viewing.
The grounds feature a special sundial that automatically adjusts for the changing speed of the sun throughout the year. This unusual design uses a curved reference line instead of a straight one to show how clock time differs from solar time.
