The Maria Mitchell Aquarium is part of the broader Maria Mitchell Association (MMA), a non-profit organization founded in 1902 to honor the legacy of Maria Mitchell, America's first female astronomer and a Nantucket native. Mitchell was not only an astronomer but also a naturalist with a keen interest in marine biology, making the aquarium a fitting tribute to her diverse scientific pursuits. The aquarium itself is situated on the historic site of the former Nantucket Railroad ticket office at 28 Washington Street, directly on the shoreline of Nantucket Harbor. It opened in 1997 and has since expanded from a single room to three indoor rooms and two outdoor touch tanks. The Maria Mitchell Association has plans for a significant expansion, moving to 33 Washington Street and developing a larger Discovery Center and Aquarium. This new facility, expected to be about 8,000 square feet and completed by 2029, will feature an expanded, state-of-the-art aquarium and marine biology lab, alongside a learning center and exhibit area. During construction, a temporary aquarium will be in operation.

What to do here

Engage with the knowledgeable interns and staff who provide educational context about the animals. Participate in a "Feeding Frenzy" session to see animals being fed. Explore the touch tanks for a hands-on experience. Discover the diverse local marine life through various exhibits. Consider joining one of their marine ecology field trips or seal cruises during the summer months.

Seasonal info

The aquarium operates during the warmer months, typically collecting and displaying local species from the waters around Nantucket. All specimens are released back into the wild at the end of each summer season during an annual "Release Day" event, usually in October. This means exhibits are always changing based on what is found seasonally, and sometimes even stray tropical fish can be seen.

Accessibility

While specific details for the current temporary location are not extensively detailed, the Maria Mitchell Association aims to provide an inclusive environment. The Steamship Authority ferries to Nantucket are wheelchair accessible. For aquariums generally, early morning visits can be less crowded, which might benefit visitors seeking a calmer experience.
