Third Annual Nantucket Green Crab Week

Tess McCarthy • August 8, 2022

Nantucket, MA – Join the Nantucket Maria Mitchell Association (MMA), Nantucket Land Council (NLC), and Sustainable Nantucket (SN) for the third annual Nantucket Green Crab Week! The MMA, NLC, and SN will be offering fun daily events from August 8th to August 12th to learn about, and take action against, invasive European green crabs on Nantucket.


European green crabs were first introduced to North America in the 1800s, likely traveling the ballast water of merchant ships from Europe. This invasive species is now abundant on Nantucket, threatening crucial aquatic resources, including eelgrass beds, shellfish populations, and native crab communities here on the island. Together, as a community, it is possible to help prevent green crabs from destroying the natural resources that make Nantucket’s waters so special! So please come join us during Nantucket Green Crab Week to learn more.


The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. 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.


Nantucket Land Council is a 501(c)3 environmental advocacy organization – protecting and preserving open space, harbor, pond, and groundwater, and advocating for the environment at Select Board, Planning Board, and Conservation Commission meetings. The Nantucket Land Council also hosts the State of the Harbor Forum each year and Oysterfest each November to educate residents on the state of our water resources, and what we can all do to help maintain this critical resource. For more information on the Nantucket Land Council’s environmental work and initiatives, please visit https://www.nantucketlandcouncil.org.


Founded in 2000, Sustainable Nantucket’s mission is to preserve the community character of Nantucket while sustaining its economic and environmental vitality.

Sustainable Nantucket (SN) is a grassroots, local, non-profit organization that is building a more locally-based and self-reliant food system on-island through education, advocacy, training, and partnerships which include farmers, fishermen, local food producers, schools, restaurants, and other community stakeholders.

Maria Mitchell Vestal Street Observatory: Conserved, Refreshed, and Renewed

By Jascin N. Leonardo Finger • August 11, 2025
After many years on the making, we are happy to officially announce the re-opening of the Maria Mitchell Vestal Street Observatory – also fondly referred to as the MMO. As you may have seen on the Maria Mitchell’s Attic bog, this has truly been more than a multi-year labor of love. Way back in 2016, we began the first steps with a structural assessment by structural engineer, John Wathne of Structures-North. That, coupled with an earlier Conservation Assessment Program grant from Heritage Preservation and supported by the Institute for Museum and Library Services that allowed the MMA to hire architectural conservator, Michael Devonshire, began us on our path to conserve the historic MMO. Grants from the Community Preservation Act and the M. S. Worthington Foundation supported the conservation work on the 1908 Observatory and its 1922 Astronomical Study. Masonry and grout were repaired, rusted iron lintels over windows and doors were replaced with steel and work was completed to the “parapets.” This sounds simple – it was not – it was a multi- year project to work with the masonry and to create a matching grout. Wayne Morris, the mason, became a fixture on Vestal Street again – as he did all the masonry conservation and work on the exterior of the Research Center. Once the MMO’s exterior was weather tight and the interior masonry work completed, the rest of the crew moved in to conserve the plaster, re-paint, and conserve the original 1922 bookcases and woodwork in the Study. Paint was removed from the dome bringing it back to its original glory. Cement floors were cleaned and treated and electrical wiring was updated and new lighting put in the Study. A major renovation was also conducted concerning the “Seminar Room” – a 1987 addition to the west of the MMO – which was completed in 2024. This was funded in large part by Mitchell family descendant and former (now honorary) MMA Board Member, Richard Wolfe. New office spaces were created for astronomy staff, updates were made to the astronomy intern workspace and meeting space, and a new accessible bathroom was completed. We also owe a huge debt of gratitude to two other board members in this work, particularly with the Seminar Room – Elizabeth Markel and John Wise. We would like to thank everyone for their roles in making this long journey a success and for doing all of this important work. Thank you does not express it well enough – they have truly all been heroes of the MMO. We are beyond grateful. THANK YOU and WOW it all looks incredible!

Glass Plate Photographic Collection

By Jascin N. Leonardo Finger • August 4, 2025
With the help of Edward Pickering from Harvard, the MMA was able to develop a research program and realized that a photographic telescope would be necessary. Funds were raised and by November 1913, a 7.5-inch photographic telescope was installed. Using Maria Mitchell’s 5-inch Alvan Clark telescope as a guide for the larger photographic telescope, the photographic telescope had a lens from Thomas Cooke and Sons of York, England and a cast-iron pier, mount, and clockwork by Alvan Clark & Sons in Cambridge, MA. The pier, mount, and clockwork are still present in the MMO – the pier and mount still utilized but by a 17-inch research telescope purchased with a grant from the National Science Foundation. The glass plates taken of the night sky at the MMO total more than 8,000 and they are still utilized for research. They capture a moment in the night sky that can never be captured again – just like a regular photograph. In order to capture the image of the night sky, exposures could last for as long as three hours or more. Glass plates were heavily used for researching variable stars. They also afforded opportunities for new discoveries that could go unnoticed when one looked through a telescope by eye. Glass plates are gelatin-coated dry plate negatives that first came into use in the 1870s. They were utilized well into the late twentieth century particularly because they did not shrink or deform like plastic film. At the MMA, we continued to take glass plates of the night sky until 1995 when we had the opportunity and funding to update to a CCD camera – charge-coupled devices. While the CCDs provided many improvements, they still did not have the detecting area and resolution of glass plates. Technology continues to evolve, and the MMA with it, as we work with new methods to capture the night sky photographically. JNLF
