Maria Mitchell In Her Own Words

Jascin N. Leonardo Finger • May 6, 2019

May 6, 1878 Between the clouds, Miss Spalding obtained 7 photographs of Mercury on the Sun. It is a comfort to me to be able to plan and do a new kind of work. The large telescope worked better than usual, Clark having just been to the Observatory.


Maria Mitchell and her students photographed the Sun on every clear day and as such were able to photograph the transit of Mercury and the rarer transit of Venus – the planet for which Maria had calculated the ephemeris for the US Nautical Almanac for many years. She was the first woman computer for the Nautical Almanac and likely, the federal government. In its archive collection, the MMA has several images that Maria and her students completed of transits of the sun, including the one of Venus which was taken by Elizabeth Rebecca Coffin, an artist of some renown and also a child of two Nantucket Quakers.


Apparently, Alvan Clark had recently visited Maria and the Vassar College Observatory and made some adjustments to the telescope. He was the premier telescope maker in America – and the man who made Maria’s five-inch – monies for it were a gift from the Women of America – a subscription overseen by Elizabeth Peabody.

Nantucket Maria Mitchell Association to Host Annual Aquarium Release Day Saturday, October 10

September 30, 2026
The Nantucket Maria Mitchell Association (MMA) announces that its annual Aquarium Release Day will take place on Saturday, October 10, 2026 from 10am - 12pm at the MMA Aquarium at 32 Washington Street. A sensory-friendly half hour will be offered from 9:30 – 10am. Join MMA staff to help the staff release this season’s Aquarium inhabitants back into the ocean. This community event is FREE to the public and a great opportunity to learn and celebrate the marine life that lives in the waters of Nantucket Island. The MMA Aquarium is dedicated to educating the public on the importance of biodiversity in our unique marine ecosystems found here on Nantucket. Each summer, the MMA Aquarium Manager, Chelsea Petrik, as well as her team of dedicated college interns and volunteers, explore the shores of Nantucket to find and document an assortment of over 7,500 individual marine animals, most of which are recorded and released. They snorkel, seine, and beachcomb to collect over 300 different marine animals. The animals are studied and cared for at the Aquarium so that the MMA can help people to learn more about these important marine organisms. Roughly seventy different species are featured at the Aquarium throughout the season. Local fishermen also provide the Aquarium with species they come across in their nets and at the end of their lines. Pre-registration is encouraged.
