Maria Mitchell Association

Operating an Aquarium, Natural Science Museum, two Observatories and a Historic House, the Nantucket Maria Mitchell Association (MMA) is a private non-profit organization located on the island of Nantucket, Massachusetts. Aquarium: Locally-collected specimens are on exhibit. Displays are always changing and include anything from seahorses to octopuses to sharks! Get a “feel” for the local ecosystem at our touch tank, home to crabs, clams, baby horseshoe crabs, and more! Great for kids and adults alike! Natural Science Museum: A cross between a classic natural history museum, a zoo, and a science center, the Maria Mitchell Natural Science Museum is a great place to learn about the plants, animals, and birds of Nantucket. See live turtles and snakes! Loines Observatory: See distant planets, stars, galaxies and more through a telescope! Stargazing nights with our expert astronomers are a unique way to spend an evening enjoying Nantucket's clear and dark skies! Check our website for specific information about Stargazing dates and times. Historic Mitchell House: Take a trip back in time to 1800s Nantucket! Built in 1790, this typical Quaker house was acquired by the Mitchell family in 1818. The home became a museum in 1903 when the Maria Mitchell Association’s founders acquired the house to preserve the legacy of Maria Mitchell herself.
