Nantucket MMA and Nantucket Lights Welcome James Lowenthal as Featured August Science Speaker Series

August 7, 2025

NANTUCKET, MA— The Nantucket Maria Mitchell Association (MMA), in collaboration with Nantucket Lights, announces that it will host James Lowenthal, PhD, the Mary Elizabeth Moses Professor of Astronomy at Smith College, as a featured presenter for its August Science Speaker Series. The presentation, “The Magic of the Night... and How We Can Save It,” will take place on Wednesday, August 20 at 7pm in person at 33 Washington Street and via Zoom. The event is free to all.

 

Do you love seeing the Milky Way from Nantucket? Do you enjoy Nantucket's beautiful gardens by day? The naturally dark night is one of Nature's greatest gifts. Humans and all other life on Earth evolved to depend on bright days and dark nights, and for thousands of generations, humans have turned to the night sky for inspiration, connection to our ancestors and culture, religion, science, and awe. Pollinators, migrating birds, marine life and plants all need natural darkness at night to thrive. Join Smith College Professor of Astronomy, James Lowenthal, on an illustrated tour of the magic of the night and learn how, together, we can preserve that night magic by taming the growing threat of light pollution -- a global problem with a local solution.

 

James Lowenthal is the Mary Elizabeth Moses Professor of Astronomy at Smith College in Northampton, Massachusetts. He received his BS in Physics and Astronomy from Yale and his PhD in Astronomy from the University of Arizona. He studies the formation and evolution of galaxies, especially actively star-forming galaxies. He leads the local advocacy group Northampton City Lights and the Massachusetts chapter of DarkSky International; chairs the Light Pollution Sub-Committee of the American Astronomical Society’s Committee for the Protection of Astronomy and the Space Environment; and is President of the International Astronomical Union's Commission on Site Protection (i.e., light pollution). He spends as much time outdoors under the night sky as he can.

This event will be held both in person and via Zoom. Pre-registration is required to attend either option.

The Science Speaker Series is generously sponsored by the Maria Mitchell Association’s lead sponsor, Bank of America.

 

Nantucket Lights, founded in 2021, is a nonprofit, all volunteer citizen advocacy group exclusively dedicated to preserving and protecting Nantucket’s nighttime environment and heritage of dark skies by raising awareness about light pollution on the island and advocating for environmentally responsible outdoor lighting. 

 

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.

After many, many years of service, our picket fences are getting a much needed replacement. We are starting with the fence on the north side of Vestal Street along the front of the Maria Mitchell Vestal Street Observatory (MMO). This fence is being replaced with part of a grant from the Community Preservation Act. The grant was for the exterior conservation work and landscape issues related to the MMO. The current fence is approximately thirty-five years old so it did rather well. It had replaced a very old fence – one I wish we had kept! But it had been hit many times by cars and had so much paint on it, they decided to replace it. We have small part of that fence still and we will be reproducing it for all the fences we are replacing here on Vestal. The fence is not much different than a normal picket here on island – it’s a hair shorter but it also has a sort of rolled top – not this cut style. I am excited to have this fence back! The new fences are being built by Michael Gault – owner of Gault Woodworking and a Nantucket Preservation Trust Traditional Building Methods award winner. His work is incredible – and lucky for us – he loves building fences!  So keep an eye out – work has begun already. The south side where the MMA Research Center and Hinchman House are located will be done in the fall in the same style. JNLF

NANTUCKET, MA – On Thursday, June 11, 2026, the Nantucket Maria Mitchell Association Aquarium, Hinchman House Natural Science Museum, Historic Mitchell House, Vestal Street Observatory, Loines Observatory, and the Maria Mitchell Association Research Center will open for the 2026 summer season. The Historic Mitchell House, located at 1 Vestal Street, will be open for tours Monday–Friday, 10:00AM– 4:00PM, and Saturday 10:00AM–1:00PM. Built in 1790, this traditional Quaker house was acquired by the Mitchell family in 1818. The home became a museum in 1903 after the Maria Mitchell Association’s (MMA) founders acquired the House in 1902 to preserve the legacy of one of Nantucket’s most celebrated daughters. The House contains many stunning artifacts from the Mitchells’ daily life in the nineteenth century, including many of Maria’s personal items such as beer mugs, opera glasses, and her Dollond telescope. The House is well known for the remarkably preserved example of faux-wood grain painting in the kitchen from the 1850s. The Vestal Street Observatory, next to the Historic Mitchell House, will be open for tours Monday – Saturday, 11:00AM–1:00PM. Built in 1908, the Observatory’s original dome now houses an 11-inch research telescope. Public accessible spaces include the Astronomical Study which displays historic astronomical collections, including Maria Mitchell’s 5-inch Alvan Clark telescope from 1858, and the Pillar Room where changing exhibits are featured. The current exhibit, “The Mitchells: A Family Constellation” showcases members of the Mitchell Family. The MMA Aquarium, located at 32 Washington Street, will be open Monday–Friday, 10:00AM–4:00PM, and Saturday 10:00AM–1:00PM. Located on the waterfront of Nantucket Harbor, the MMA Aquarium displays local Nantucket species and offers an immersive place to learn about the amazing marine life of the island. Displays are consistently evolving and range from crabs and shellfish to fish and eels. All the hungry creatures at the Aquarium are fed daily during our “Feeding Frenzy” program, where attendees learn about and observe the unique feeding behaviors of our animal ambassadors. All ambassadors of the MMA Aquarium are locally collected and are re-released back into the wild at the end of the season during the annual “Release Day" event, scheduled for Saturday, October 10 this year. The Hinchman House Natural Science Museum, located at 7 Milk Street, will be open Monday–Friday, 10:00AM–4:00PM, and Saturday 10:00AM–1:00PM. An exciting space for inquisitive minds of all ages, the Natural Science Museum is a cross between a classic natural history museum and a science center. It is a beloved place to learn about the plants, animals, and birds of Nantucket. All the hungry creatures at the Museum are fed daily during our “Ravenous Reptiles” program, where one can learn about the unique adaptations of turtles, frogs, snakes, and more. The “Keeper for a Day” program, new this year, allows children and young teen participants to prepare diets, feed members of our living collection, clean and refresh enclosures, and learn how to keep the MMA animal ambassadors healthy and thriving. The Loines Observatory, located at 59 Milk Street Extension, will be open to the public for Stargazing Open Nights from 9:30-10:30PM Mondays, Wednesdays, and Fridays through June 27. Beginning June 29 through August, Open Nights will be offered Monday, Tuesday, Wednesday, and Friday. Please view our calendar at www.mariamitchell.org/calendar for up-to-date information as Open Night times will change throughout the summer. All Open Nights are pre-registered programs and are weather dependent. When a special natural occurrence is forecast in the night sky – such as meteor showers, a new comet, or a lunar eclipse – the Loines Observatory is the place to be. During Stargazing Open Nights, visitors can view a variety of astronomical objects in the night sky through our 8-inch Alvan Clark refractor and our modern 24-inch research telescope. MMA staff will lead constellation tours, and patrons can learn about the innovative research conducted by our astronomers and interns – a fantastic opportunity for all your astronomy-related questions to be asked and answered. The Maria Mitchell Association Research Center, located at 2 Vestal Street, will host “Biological Collections Open Hours” by appointment only. At Open Hours, visitors can learn about the biological collections and their importance to science, in addition to examining different specimens during each session. From specimens of birds and mammals to insects and plants, you never know what will be on display! Appointments can be scheduled by emailing programs@mariamitchell.org. MMA Property Passes can be purchased for the Aquarium, Hinchman House Natural Science Museum, the Historic Mitchell House, and the Vestal Street Observatory. A property pass includes admission to the four museum sites. The cost of a property pass is $24 for children and $42 for adults. Open Night admission at Loines Observatory is $17 for children and $27 for adults. Admission to MMA properties is free to MMA Members and Stargazing Open Nights and all programs are discounted 20% for members of the MMA as well.

I love to walk in the cemetery. The stones are quite beautiful, as is the landscape. Is it sad? Yes, but its not creepy or scary. Many of these people have been forgotten. Though at the time of their death, their family did not think they would be – nor perhaps did those people before they died. I find it sad to come across fallen or broken stones, stones that have been overgrown with weeds or a well-intended shrub that has now taken over the space after 100 years or so. Stones covered so heavily in lichens that you cannot read the name of the person buried there invokes sadness and is worrisome for the damage the lichen can do. The young children, infants, teenagers, and young adults – that is all the more painful – as they were short-changed on life. But the old people – those who lived a full and very long life – they got all the time. And while it’s sad, they are gone, their life was full – no cut off at an early age. I have written about cemeteries before. I have noted that I clean stone monuments (gravestones) and run a workshop once a year to teach people how to properly clean stones. There is a bit of a movement afoot – especially with Instagram and TikTok – where people record themselves cleaning stones and showing people how to do it. Please be careful – some people are not trained and are doing it the wrong way. The sound of a metal scraper sets my teeth on edge – that is NOT how you clean historic gravestones – THAT erodes the stone and damages it forever. So, until you have some in-person training by someone who is qualified, do not do it! JNLF This year’s stone cleaning workshop will be Saturday, June 13 from 10-Noon. Registration is necessary and there is a small fee – it covers the cost of the supplies.
