Thursdays Under the Stars at Mystic Seaport Museum

Mystic Seaport Museum invites visitors of all ages to experience an evening of stargazing and celestial discovery during its monthly Thursdays Under the Stars series. Held in the Treworgy Planetarium, these after-hours programs feature an engaging update on the stars, constellations, and planets visible from local backyards.

Programs will take place on the first Thursday of each month—September 4, October 2, November 6, and December 4, 2025—from 7 pm to 9 pm. Capacity is limited to 60 participants. Admission is $15 for adults and youth ages 4–17, free for children ages 3 and under, and $12 for Museum members.

The event will be held at Mystic Seaport Museum, 75 Greenmanville Avenue, Mystic, CT 06355. Tickets are timed and can be purchased in advance through the Museum’s website.
