Speaker Nights
Evenings begin with a 40-minute illustrated presentation within the Administration building on a variety of exciting astronomy topics and the history of the facility. Following the presentation, the 74” telescope will be demonstrated. If the sky is clear, the dome will be opened and the telescope pointed to an interesting celestial object for the visitors to view. Although the sky is not always clear enough for viewing, programs run regardless of the weather (i.e. - a talk and demonstration of the 74” telescope are always provided). On clear nights, smaller telescopes may be available for celestial viewing; on cloudy nights, Visitors can attend a second presentation in our SkyLab for a simulation and discussion about the current nighttime sky.

Workshops
Intro to Astronomy
Explore the wonders and mysteries of the nighttime sky. What is the Milky Way? What are stars made of? How did the Earth and Moon form? Why do we believe the Universe began in a "Big Bang"? We will discuss these and other topics, as well as the underlying laws of nature and the tools we use to explore the universe. Join us on this four-week journey of cosmic discovery, every Wednesday from Jan 18 to Feb 8! No prior knowledge of Astronomy is required. All concepts and theories will be explained and your questions answered in simple language by our professional astronomers. A registered adult must accompany all registered participants under the age of 16.
We will update this page with dates and times for each course, as well as direct links for registration, once they become available.
