The Chester County Astronomical Society was formed as a non-profit organization dedicated to the education and enjoyment of astronomy for the general public. The Society holds meetings (with member or guest speakers) and observing sessions once a month. Anyone who is interested in astronomy is welcome to attend meetings and become a member of the Society. In addition to the monthly meetings and observing sessions, the Society also provides a variety of services to the public, including astronomy classes as well as telescopes and expertise for "star parties" for school, scout, and other civic groups.

NASA’s Voyager 1, the most distant human-made object, recently reconnected with Earth using a backup transmitter last used in 1981. This legendary spacecraft, over 15 billion miles away, showcased remarkable resilience by autonomously switching systems. Discover how the Deep Space Network restored communication, allowing Voyager to continue sending data from interstellar space. Join us to learn about the significance of Voyager 1’s achievements and what this means for future space exploration.

The society schedules monthly observing sessions in the Myrick Conservation Center of the Brandywine Red Clay Alliance. The observing sessions, which are planned around the new moon, are open to the public and announced in the Society's newsletter, Observations. Owning a telescope or binoculars is not required; anyone interested in observing the heavens is welcome to show up. If you do have a telescope and need help using it, our observing sessions are a great place to practice and learn from other society members.

The Chester County Astronomical Society's regular monthly meetings include a presentation from an invited speaker or the demonstration of an astronomical project by one of the Society's members. After the presentation, a brief business session is held to review the status of society activities. Meetings typically last 1-1/2 to 2 hours including an informal conversation over refreshments before the start of each meeting.

The Society meets at 7:30 PM the second Tuesday of each month in the Merion Science Center (former Boucher Building) at West Chester University (corner of South Church Street and Rosedale Avenue, West Chester, Pennsylvania). Click for Directions and Maps.

CCAS has partnered with Chester County Lifelong Learning to offer a six-week program meeting in the autumn of 2024. For more information, including dates of the classes, contact our Education Co-Chairs. Learn more about the location, the topics covered, and how to register on the classes page.

The Chester County Astronomical Society offers "nights out" to interested organizations including local schools, scouting groups, and other civic groups for the purpose of learning more about the heavens. For example, scouting groups often hold them to earn badges for their members. If your organization is interested in hosting a "night out", please contact us.

The West Chester University Department of Geology & Astronomy hosts a planetarium show open to the general public on the 2nd Friday of each month. The WCU Planetarium is located in the Schmucker Science Center on Church St. To locate the planetarium, view the campus map.


The shows start promptly at 7:00 P.M. ET and run approximately one hour in length. Late arrivals will not be permitted to enter the planetarium. Each show includes an overview of what is visible in the current night sky and a special focus on some aspect of astronomy.

Reservations are required because the planetarium has limited seating. For contact information, visit the WCU Public Planetarium Shows webpage.
