The Birth of the Maria Mitchell Observatory: Celebrating Over 100 Years of Discovery

Jascin N. Leonardo Finger • June 30, 2025

As we are now complete with the conservation of the historic Maria Mitchell Vestal Street Observatory (MMO), I thought it would be good to post a series of blogs concerning it history and activities, as well as some of the amazing people who have made it what it is over the last 100 plus years. Therefore, over the next few weeks, the focus will be on the MMO.  And it is now open for tours – Monday through Saturday 11-1PM.


Founded in 1902, the Nantucket Maria Mitchell Association (MMA) had its beginnings in the Mitchell House where Maria Mitchell was born. Over the first few years, the preservation of the Mitchell House, family artifacts, and the collection and display of Nantucket’s native flora and fauna, as well as a small library, were the key components of the MMA. Special “Moon Evenings” were held on the lawn and people observed Nantucket’s night skies using several small telescopes, including William and Maria Mitchell’s two-and-three-quarter-inch Dollond telescope.


The popular evenings led to the inevitable – a desire and need to expand based on the demands of the visitors to, and members of, the MMA. In 1906, Lydia Hinchman, a founder of the MMA and a family member, purchased the house and lot adjacent to the Mitchell House. The house – once the home of William Mitchell’s father and mother – was taken down.


The MMA began a dialogue with the Harvard College Observatory and its director, Edward Pickering, Ph.D. The connection to Harvard was to become essential to the success of the beginning years of the Maria Mitchell Observatory and continued a legacy of friendship and work – Maria Mitchell and her father worked with the Bonds who once ran the observatory at Harvard and the families were close friends.


Besides his assistance, Pickering asked a member of his staff, Annie Jump Cannon, to assist the MMA. This “provided an indispensable collaboration for Nantucket astronomy,” with Cannon spending two weeks on the island in 1906 and 1907 lecturing and teaching. While back at Harvard, she continued to teach the students on Nantucket by mail. Cannon would go on to be recognized as the leading woman astronomer of her generation and as the founder of the MMA’s Astronomy Department.

It used to be that whatever the deer or bunnies ate at my home garden, I could plant with relief in Town in the Mitchell House garden. But, over the years, it has become more difficult as we have a plethora of bunnies – multiple complaints made here in this blog – and deer that are now coming into Town year round. They have resorted, in winter, to eating ivy and while ivy is considered invasive, it has been a long-time, reliable ground cover in Town – as in a hundred or more years. Now, we have voles – which do have cycles where their population booms for a year – or two – but we have not had them in the MMA gardens at least in my memory. Now, we do and I worry about them devastating the garden in front of the Observatory which is a large, native species garden we have worked on for many years. I know climate change is definitely playing a role – it’s affecting the birth cycles of voles and allowing them to have potentially more broods. Its also potentially affecting some of their predators that may not be as prevalent and thus fewer voles are being eaten. In any case, we have tunnels galore, which is why I was happy to have ONE blossom on the heirloom morning glories I plant for Mitchell House every spring. Out of 500 or more seeds – I got one lonely blossom! The voles are attacking my own personal garden – the last two summers – and I have lost many of the mainstay lilies and perennials that have been there for forty years – or they have shrunken due to their root systems being undermined and eaten. Roses are failing too. So if anyone has better ideas then solar hummers, live trap, kill trap, or Juicy Fruit gum – let me know – poisons not allowed! JNLF Update: Got four more blossoms - but still!

NANTUCKET, MA— —The Nantucket Maria Mitchell Association (MMA) announces that it will host its new Director of Astronomy, Jackie Mlingo, PhD., as a featured presenter for its October Science Speaker Series. The presentation will take place on Wednesday, October 15 at 7pm in person at the MMA Research Center, 2 Vestal Street, and via Zoom. The event is FREE to all. Have you ever noticed the dark spots that sometimes appear on the Sun’s surface? These “sunspots” are just one example of star spots—mysterious patches that appear on stars across the galaxy. Far from being simple blemishes, star spots reveal the powerful magnetic forces at work inside stars, forces that also drive solar storms and shape the space weather that can impact entire planetary systems. In this talk, Dr. Milingo will share her research on star spots and how she uses them as a window into teaching undergraduates the process of scientific discovery. She will also explore how science can reach far beyond the classroom—bringing STEM into everyday spaces and sparking curiosity across communities, from kindergartners to lifelong learners. Dr. Jackie Milingo is an observational astronomer who earned B.S. degrees in Physics and Astronomy from the University of Kansas, and a Ph.D. in Astrophysics from the University of Oklahoma. Her research is currently focused on understanding magnetic activity cycles in sun-like stars through long-term studies of starpots. Dr. Milingo joins the MMA after a year-long AAAS Science and Technology Policy Fellowship at the U.S. National Science Foundation, where she was a Fellow in the Office of Legislative and Public Affairs, as well as the Astronomy Division in the Math and Physical Sciences Directorate. Before her fellowship, she was a professor in the Physics Department at Gettysburg College for over twenty years where her work included mentoring undergraduate research students. Dr. Milingo joined the staff of the MMA in early September after a year-long, worldwide search for a new astronomer. She becomes the eighth MMA Astronomer and Director of the Astronomy Department of the MMA since Margaret Harwood, the MMA’s first astronomer, served from 1916 to 1957. Dr. Milingo has spent her career committed to generating transformative experiential learning opportunities, contributing to public education and outreach, removing barriers for students, and changing the conversation and learning spaces in astronomy, physics, and STEM in general. This event will be held both in person and via Zoom. Pre-registration is required to attend either option. To register for the free, in-person event, use the registration link below: https://112458a.blackbaudhosting.com/112458a/October-Science-Speaker-Series--Dr-Jackie-Milingo To register for the free, Zoom option, use the registration link below: https://us06web.zoom.us/webinar/register/WN_5q4kXF2rRHi8iWbFPkLN5w The Science Speaker Series is generously sponsored by the Maria Mitchell Association’s lead sponsor, Bank of America 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. ###
