Join us for a 30-minute live show to explore the autumn evening sky. Visit our closest neighbor in space, the Moon, before examining Saturn, the planet that will be most visible during the fall season. Explore the constellations of autumn—including Cygnus the Swan, Pegasus the Winged Horse, and Cassiopeia the Queen. Finally, learn how sailors used the stars to navigate across the ocean.
Join us for a 45-minute movie projected on the dome in our planetarium theater. “One Sky” weaves together short tales of cultural and indigenous astronomy from around the world—told through authentic voices, music, and breathtaking visuals that wrap around you in 360 degrees. This is an international collaboration with a simple, powerful message: no matter where we stand, we all share one sky.
Since 1960, the Treworgy Planetarium at Mystic Seaport Museum has been a center for science education, inspiring visitors to draw connections between our maritime history and the world and skies around us. When we look up at the sky, we see the very same stars that guided sailors long ago, as they developed their navigational tools and instruments. We have come a long way from the compass and sextant to the GPS units that many of our smartphones have. In order to truly appreciate the technological luxuries we enjoy today, it is more important now than ever to preserve the traditions of the past.
Your family can participate in all of our shows at the Treworgy Planetarium, each one a live program delivered by a dynamic member of the Planetarium staff. Come see the sun, moon, planets, and stars like you’ve never seen them before! You will be immersed in a sea of stars, and the constellations will guide us on an unforgettable journey through the galaxy.

If you’re wondering how our name is pronounced, think “TRUE-urr-gee.” Originally named the “Seaport Planetarium,” the Planetarium was re-named in 2009 in memory of Don Treworgy. Don worked at the Planetarium for 48 years, including 44 years as the Director, and was beloved by the Museum’s staff, volunteers, and visitors. The current staff is honored to work at a Planetarium that bears Don’s name, and his memory inspires us to continue the mission of education in the fields of astronomy, navigation, and maritime history.
The Planetarium Lobby currently houses an exhibit titled, “By the Light of the Stars: Celestial Navigation Across Cultures.” People in every culture have watched the changing positions of the Sun, Moon, stars, and planets. They have used what they learn to navigate, mark seasonal changes, tell time, and locate important buildings and monuments. In this exhibit, you will learn about extraordinary feats of observation and the amazing accomplishments they made possible.
Just outside the Planetarium, an American Sweetgum tree is growing from a seed that orbited the Moon in 2022 as part of NASA’s Artemis I mission. The Artemis Moon Tree program is a modern-day reimagining of the Apollo Moon Trees of 1971, when Apollo 14 astronaut Stuart Roosa carried seeds on his journey to and from our closest neighbor in space. Our Moon Tree stands as a testament to the resiliency of life amidst extreme conditions. We hope it inspires you to dream of the possibilities that the future holds. If a tiny seed can survive a 500,000-mile journey to the Moon and back, what else is possible when it comes to exploration?
