Maria Mitchell Vestal Street Observatory Conservation Update: February 2025

Jascin N. Leonardo Finger • February 3, 2025

We are still quietly working away. Now that the paint and plaster repairs are done, the woodwork and shelving has been conserved, and the floor has been redone in the Astronomical Study, we have turned to the concrete floors. These are being worked on by Evita Caune of Riptide Finishes – she had done Hinchman House’s cellar floor and those in the Research Center. The Observatory cellar floor is coming along and she is also working on the Pillar Room – so named because it houses the pillar that supports the telescope in the Dome Room. If there was an original finish on any of the three concrete floors – the Pillar Room, the Dome Room, the cellar under the Astronomical Study – it is gone. They applied many layers of paint that eroded and chipped with time. I do now know why the Pillar Room had a red floor at one point (took me long enough) – probably to match the red tile they put on the original wood floor in the Astronomical Study. Evita is giving us a nice clean coating in the Pillar Room and the cellar and we may have a bit more fun with the floor in the Dome Room – all of this is reversible which comes from a conservation perspective.  All the interior conservation work was funded by the Community Preservation Act – as was the exterior conservation.


One note – the Astronomical Study’s original floor was a total loss as far as finish is concerned. I may have noted this before. It was truly sad. The original wood floor was covered in multiple layers – tarpaper glued to the wood. Then a layer of red tile (tested and was safe), then another layer of tarpaper and glues. Then foam padding and a 1980s blue wall-to-wall carpet – they liked that carpet so much it used to be in the Astronomer’s Cottage too! We thought the tar paper beneath the tiles would be easily removed from the wood. It was not. It had basically melted and seeped into the floor so we have to lightly sand the floor and then refinish it. That was quite sad – but at least we have the original wood floor intact.

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • February 17, 2026
1881, Feb. 26. Miss Whitney read Frances Power Cobbe’s “Lectures to Women” aloud to me. In the main they are excellent. I agree at almost every point. What she says about the duty of women in veracity, in cultivating both physical and moral courage, etc., in demanding not “favor but justice” . . . Mary Whitney would become the first president of the Nantucket Maria Mitchell Association. She was one of Maria’s first students and ultimately her replacement at Vassar College. She also took over for Maria when she left the College for a brief illness in 1880. On her second trip to Europe in 1873, Maria would seek Frances Power Cobbe out at her home. A suffragette, Power Cobbe was a philosopher and writer among other things, including an animal rights activist when it came to experimentation on animals. Born into a wealthy family in Ireland, Power Cobbe would travel in Europe about the same time as Maria did in 1857, meeting some of the same people Maria would meet such as Mary Somerville (Maria’s hero and an astronomer, mathematician, scientist, and polymath) and Harriet Hosmer (sculptor). I should not note this but Maria wrote about Power Cobbe’s large head –further stating that being a large woman, she would have a large head. Reviewing images of Power Cobbe, I hate to say it but I cannot disagree – with my apologies to Ms. Powers Cobbe. JNLF

Nantucket Sorosis

By Jascin N. Leonardo Finger • February 9, 2026
On August 6, 1872, the first meeting of the Nantucket Sorosis Club took place at the home of Sarah Cathcart on Main Street. Originally founded in New York in 1868, several of its founding members were Nantucket women such as Maria Mitchell and Reverend Phebe Coffin Hanaford, and the club appropriately found its way to Nantucket where Hanaford first publicly announced its inaugural meeting from the pulpit of the Unitarian Church. Its purpose: the “intellectual improvement of its members, by means of written essays, select readings, recitations and discussions upon the current questions of the day.” It was Hanaford and Nantucket summer resident Rebecca Morse – members of the New York Sorosis – who developed the idea of founding a Nantucket Sorosis. Like the sewing circles founded earlier in the nineteenth century, the development of a Sorosis on Nantucket may have been in part to aid women not only during a period of economic decline on the island, but to help those women who found that they were now losing their jobs as whalemen returned to the island for good and tried to “reclaim” the jobs of men. It was also a logical club to have for women on the island – given the history of their playing such an integral role in all aspects of island life. Two other island women involved with the Nantucket Sorosis Club were Eliza Starbuck Barney and the Reverend Louise S. Baker. The main Sorosis club came about as a reaction by female journalists barred from attending and reporting on Charles Dickens’ first public lecture in the United States in New York City. They quickly came together to created forms of support for one another in their field, expanding to include women working in a variety of other fields – science among them. Thus, Maria Mitchell was one of the founding members when the first official meeting was held at Delmonico’s in NYC. With a thirteen-article constitution, the Nantucket Sorosis had a board of directors with officers being elected annually. The club hosted lecturers and orators, discussed social and political issues – particularly those of woman suffrage – and also discussed art, literature, travel, and current events. The Nantucket Sorosis lasted approximately thirty years. Little is known about who was involved outside of key players and when exactly the group folded and why, but the last printed material that can be located dates to 1903, and by that time most of the Nantucket Sorosis members were in their seventies and eighties.

Nantucket Maria Mitchell Association NSF-REU Interns Attend 247th American Astronomical Society Meeting

February 5, 2026
NANTUCKET, MA—On the occasion of the 247th American Astronomical Society (AAS) Meeting, and the 179th anniversary year of the discovery of Maria Mitchell’s Comet, the 2025 astronomy interns from the Nantucket Maria Mitchell Association (MMA), journeyed to Phoenix, AZ, to represent the MMA and present their research. Building on the legacy of Maria Mitchell, the first female American astronomer, the MMA offers STEM research and education opportunities to interns from across the country via their paid internship programs. The MMA’s Maria Mitchell Observatory has operated a National Science Foundation funded Research Experiences for Undergraduates (REU) program for decades. The REU is funded by a generous grant from the U.S. National Science Foundation (NSF) which allows the MMA to bring six undergraduate students to Nantucket each summer. These talented and promising students are selected out of a pool of hundreds of applicants from across the United States. From January 4 – 8, 2026, the MMA’s most recent NSF-REU students presented their work at the winter AAS meeting on subjects ranging from the characteristics of dust around and between stars, to various aspects of supernova explosions. MMA Director of Astronomy, Dr. Jackie Milingo, attended the conference and presented each student with a bound volume of their collected research papers. “The MMA’s long-standing REU program has nurtured hundreds of budding scientists over many decades. It’s always inspiring to see these students shine and make the most of this extraordinary opportunity. We’re a small program with an outsized effect on not only these students, but the future of the scientific community.” The 2025 REU students and their respective presentations are listed below. The common theme of their research was dust. This dust is made of familiar elements like carbon, oxygen, silicon and iron is similar to grains of sand or ash. Even though these dust grains are a small part of our Galaxy, they are very important because they can block the light coming from everything astronomers study. Understanding this dust helps us to understand how it is formed and how it affects the light that must travel vast distances across our Milky Way to get to our telescopes. This past summer’s NSF-REU interns and their research presentations which they presented at the AAS are: Madison Gerard (University of Texas at Austin) : SN 2024abfl: An Absolutely Flat and Low-Luminosity Interacting Type II Supernova Kaylee Perez (Texas State University) : Exploring the Link Between Dust Extinction and Attenuation with Simulated Data LaurenBarkey (CaliforniaPoly Pomona) : Peek-a-Boo: Exploring the NEOWISE Lightcurves of RCoronae Borealis Stars Aiden Agostinelli (University of Montana) and Ben Radmore (University of Michigan) : When the Dust Settles: Late-Time MIRI Imaging of SN 2011ja Image: 2025 NSF-REU Interns, Madison Gerard, Lauren Barkey, Benjamin Radmore, Aidan Agostinelli, and Kaylee Perez with MMA Director of Astronomy, Dr. Jackie Milingo.  The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages. ###
