BOSTON, MA — The Museum of Science, Boston, in partnership with Boston Harbor City Cruises, is pleased to announce the return of the “Sea the Stars” boat cruises, offering an unparalleled summer experience for astronomy enthusiasts and stargazers alike.

Educators from the Museum of Science will act as night sky tour guides for passengers as they set sail on Boston Harbor to see the stars and planets. With an unobstructed view of the sky, passengers can map out constellations, tour our galaxy, and catch the Perseid meteor shower, which happens every year from mid-July to late August. In addition to expert commentary, guests will have access to related videos, content, and engaging activities that will deepen their learning aboard the high-speed catamaran.

“Our renewed partnership with Boston Harbor City Cruises gives passengers a fun, immersive opportunity to ignite curiosity and deepen the understanding of our natural world and connection of our planet and the cosmos,” said Dani LeBlanc, director of the Center for Space Sciences at the Museum of Science. “This unique experience allows our talented staff to share our deep love and passion for astronomy and space with a wider audience outside of the Charles Hayden Planetarium.”

After sunset, the three-hour boat cruise departs from Long Wharf, Boston, and cruises beyond city lights to ensure optimal night sky viewing. If it is raining or the cloud cover is thick, we will have to cancel due to the lack of visibility of the stars.

“Boston Harbor City Cruises is excited to partner with the beloved Museum of Science and their educators from the Charles Hayden Planetarium to host a series of Sea the Stars Cruises this summer.  We look forward to having astronomy and space enthusiasts on board,” said Bob Lawler, vice president & general manager of Boston Harbor City Cruises.
