Join Us Tonight
For the Release of Stargazer Stout at Cisco Brewers!
 
Image item
Dear Friends:
 
On this day in 1847, a 29-year-old Maria Mitchell, then serving as librarian at the Nantucket Atheneum, climbed the stairs to the rooftop of the Pacific Bank. There, she spotted something extraordinary — a comet. That discovery would change her life forever, earning her international recognition and becoming one of the many “firsts” that defined her legacy.
 
Today, we honor that moment of discovery in a very Nantucket way. From 4–7pm at Cisco Brewers, Head Brewer Silas Gilbert will release the Stargazer Stout, “a beer designed to be as unique as Maria Mitchell herself.” 
 
We are deeply grateful to Cisco Brewers for their creativity and generosity, as $1 from every pint sold will be donated to the Maria Mitchell Association.
 
I like to think Maria would find this amusing — a “medicinal,” as she once called beer, brewed in her name on her beloved island more than a century after she last gazed at the stars from a rooftop.
 
So please, join us for a toast to Maria Mitchell, to Comet C/1847 T1, and to the ongoing legacy of her work — for women, for astronomy, for science, and for the wonder found in nature and among the stars.
 
Maria Mitchell today is not just one woman.
She is every curious mind that defies expectation.
 
Cheers to you, Maria Mitchell.
 
With gratitude,

Aquarium Release Day!
 
Be part of the journey as we return our marine friends to their ocean home.
Aquarium Release Day
MMA Aquarium, 32 Washington Street 
Saturday, October 11 | 10am - 12pm
Sensory Friendly Half Hour 9:30 - 10am
 
Each summer, the Maria Mitchell Association Aquarium Manager, Christina Norman and her team of dedicated interns and volunteers, explore the shores of Nantucket and collect an assortment of marine life to feature at our popular Washington Street Aquarium.
 
The MMA Aquarium is dedicated to educating the public on the importance of biodiversity in our unique marine ecosystems found here on Nantucket. MMA staff snorkel, seine, and beachcomb to find over 100 different marine animals to learn about and care for throughout the season. These marine animals represent roughly 70 different species collected by our staff in tandem with local fishermen.
 
When the Aquarium closes at the end of each summer season, the MMA staff host our annual Release Day event to say goodbye to our marine friends, thank them for their lessons, and safely return them to their ocean home until we encounter them again.

Science Speaker Series

SCIENCE SPEAKER SERIES
 
Dr. Jackie Milingo
 
“Spotted Stars and     Informal STEM         Learning”
Wednesday, October 15
7pm in Person and on Zoom
Free to the Public
 
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, 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.
 
Come meet the MMA's new Director of Astronomy and learn more about her research and her work to make astronomy accessible to all.
 
Free and open to the public. Pre-registration is required.
 
Birding News

Keep Calm and Bird On!
by Ginger Andrews
 
The drought continues. So, our hope, our plea, for October is for rain, please, pretty please, with any drop or sprinkle welcome. Birds can make do, to some extent, by getting moisture from condensation on leaves, or dripping fog. Insects require plants, and plants require at least some groundwater. It is interesting to see which plants are less thirsty or have deeper roots. But, some of the inland ponds where we like to look for hidden shorebirds are out of the running this year.
Some ponds are naturally shallow: Almanack, Middle Pout, and Quaise Pond are all subject to drying up periodically.  They fill in with grasses, leaving a chance for some rare plants to sprout once they are exposed to air. This is part of the natural cycle. But in August, Reyes Pond became a cracked, turtle-vanquishing glue-pot, becoming lower than long-time inhabitants could ever recall. As it dried, a Solitary Sandpiper visited briefly, along with one Least Sandpiper. But, they moved along as the mud dried. Maxie’s Pond also had an unusual amount of exposed shoreline.  So, some of our usual “unusual” shorebird spots in the hills have suffered. The deepest kettle ponds have retained some water; some appear unchanged.  The ground water is now so low that it will take more than one winter’s rain to replenish.
 
This is yet another reason to plant native species for birds. Bayberry, Viburnum, grapes, at this time of year come into their own with food for passing migrants. Berries that may not appeal to us also attract insects, and birds eat both. Look for Cedar Waxwings, Tree Swallows, Northern Flickers, and those confusing fall warblers. But don’t despise the Grey Catbirds. They have adapted themselves to us, both in North and Central America. Watch as they glean through the tangles; they blend in with the shadows, so it’s good practice.

5th Grade Trees in The Community
 
The Maria Mitchell Association visited all fifth-grade classrooms on Nantucket for the annual Trees in the Community Program in collaboration with Annie Mendelsohn, Surfing Hydrangea Nursery, the Nantucket Intermediate School, the Nantucket Lighthouse School, and the Nantucket New School.
 
This program is made possible by generous funding from a community grant by the Nantucket Garden Club. Each year, MMA educators alongside Annie Mendelsohn, founder of the Trees in the Community Program, visit each fifth-grade classroom with the goal of sharing knowledge about tree anatomy and morphology, the importance of native tree species on Nantucket, and to encourage native tree planting on the island. After learning about native tree species, every fifth grader selects a native tree of their choice, such as White Oak, Black Cherry, Red Maple, Eastern Red Cedar, and Flowering Dogwood.  
 
On tree delivery day, Annie Mendelsohn and the MMA educators facilitate a demonstration on best practices for planting, sustaining, and protecting their Nantucket native trees. This year, the Trees in the Community program reached 155 students. By the program's conclusion, every fifth grader on Nantucket understands the benefits of native trees to the Nantucket ecosystem, learns how to identify trees via observation and dichotomous keys, understands how to determine the best place to plant their tree, and knows how to care for their native tree so that it can be enjoyed by future generations to come.

Birding in Central Park with the MMA
 
Earlier this month, the Maria Mitchell Association and Travel Sommelier hosted a special birding adventure in New York City’s Central Park, led by MMA Field Ornithologist Ginger Andrews and wildlife expert James Currie. Beginning at dawn, participants were treated to the sights and sounds of the Park alive with birdsong, spotting over 30 species spanning warblers, thrushes, waterfowl, raptors, and other songbirds. The day also included a tour of the American Museum of Natural History, brunch at The Restaurant at Gilder, and an inspiring talk by Currie, creating a memorable blend of nature, science, and community.
