Fulldome Movies

Join us at noon on weekends for an immersive experience using the Planetarium’s new fulldome projector! We will rotate through a series of movies about a special topic in astronomy, showing one movie per weekend day. All fulldome programs are 25-30 minutes long. To find out which fulldome movie is playing on the day of your visit, please stop by the Planetarium, or check the daily update, Museum Lobby monitors, or inserts posted at the Navigation Stations on the grounds.

“Winter Stars and the Mariner”

The earlier sunset in the winter season provides even more time for stargazing! Join us for an overview of the winter night sky, starting with locating the Big Dipper and using this shape to find the North Star, Polaris. Once a sense of direction is established, we will locate other well-known constellations and shapes like Orion the Hunter and Taurus the Bull. We’ll also keep an eye out for any visible planets—mostly Jupiter and Saturn, but Mercury can also be seen for part of the season. We will pay a visit to our closest neighbor in space, the Moon. And finally, we will explore ways in which sailors used the night sky to navigate the open ocean.

“Polar Night, Arctic Light”

Join us for a special look at the night sky as seen from the coldest regions of Earth. Learn about a time of year when the sun never rises (Polar Night) and see the constellations as they are viewed by the Inuit who call this region their home (Arctic Light).

Stars to Guide the Way

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 important now more than ever to preserve the traditions of the past.

Inside the Planetarium

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.

What’s in a Name?

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 its 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.
