Nantucket Maria Mitchell Association Welcomes Gail Walker, Geoff Clayton, and John Barentine as Featured Guests for the January Science Speaker Series, “How Dark is Nantucket’s Night Sky?”

January 13, 2025

NANTUCKET, MA—The Nantucket Maria Mitchell Association (MMA) announces that it will host Gail Walker, Geoff Clayton, and John Barentine, with moderator, Joanna Roche, as featured presenters for its January Science Speaker Series. Their presentation will take place on Wednesday, January 22 at 7pm via Zoom. This event is free to all.

 

“How Dark is Nantucket’s Night Sky?”

Join Gail Walker, founder of Nantucket Lights, Dr. Geoff Clayton, Interim Director of Astronomy at the MMA, and Dr. John Barentine, founder of Dark Sky Consulting, in a panel discussion moderated by the MMA’s Executive Director, Joanna Roche. Learn about the Nantucket Sky Quality Monitoring Project, a joint initiative of Nantucket Lights and the MMA launched in 2022 to collect ground-based measurements to determine how dark Nantucket's night sky is. The data collected to date establishes a baseline for assessing the effectiveness of efforts to mitigate light pollution going forward — and helps us understand how close we are to losing the ability to see the Milky Way with the naked eye. 

 

Nantucket Lights and the MMA will be explaining how this project works and plans going forward. John Barentine, retained to independently analyze the data collected so far, will discuss his findings and recommendations. 

 

Gail Walker is the founder and president of Nantucket Lights (https://nantucketlights.org), an all-volunteer, citizen advocacy group exclusively dedicated to preserving and protecting Nantucket’s nighttime environment and heritage of dark skies. A long-time summer resident of ‘Sconset, she began working on light pollution as a board member of the 'Sconset Civic Association following her retirement from the U.S. Department of Justice where she was a trial attorney for almost twenty years. In addition to leading Nantucket Lights, Walker serves on the Executive Committee of the Nantucket Civic League. 

 

Geoffrey Clayton received his Ph.D. in Astronomy and Astrophysics from the University of Toronto. He has worked for the Universities of Wisconsin and Colorado, as well as for NASA. He spent twenty-seven years as a professor at Louisiana State University. His association with the MMA goes back almost sixty years. He attended lectures and attended Open Nights at the MMA when he was a child visiting Nantucket. He still appreciates the dark skies of Nantucket now that he lives on the island full time. 

 

John Barentine is the Principal Consultant and Executive Officer at Dark Sky Consulting, LLC. He earned a Ph.D. in astronomy from the University of Texas at Austin and previously held staff positions at the National Solar Observatory, Apache Point Observatory, the Sloan Digital Sky Survey, and the International Dark-Sky Association. He is a member of the American Astronomical Society (AAS), the International Astronomical Union (IAU), and the Illuminating Engineering Society (IES), and is a Fellow of the Royal Astronomical Society (RAS). He serves on light pollution committees of the AAS, IES and IAU, and co-leads the Community Engagement section of the IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference.

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 female 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

[1855] On the 12 th [December] at 8 o’clock, I found a comet in Cetus. It is probably that seen by Bruhns in Berlin on Nov. 12. It is round and bright and moved so rapidly that in an hour I was certain of its change of place. From 8 to 10 ½ it had moved about half the diameter of my field of view. I tho’t it varied in its light but of this I am not quite certain, as I at times changed from one instrument to another, and I cannot be certain that my eye was not somewhat affected by the size of different powers, so as to affect my judgement. I would give a good deal for it to be my own possession, because it would convince me that I was not declining in vigor.  This comet, unlike her won comet of October 1, 1847, is fairly fast moving – it would take many calculations and much time for her comet to illustrate its movement – beyond just the appearance of its “tail.” Maria had made earlier comments in the month about if being a hard year – the hardest of her life. The loss of friends, her mother’s illness. But this, with other matters, buoyed her spirit and she talked about her “blessings.” This comet was one seen by Maria only eight years after her comet discovery so it seems interesting that she feels she is slipping and not as “vigorous” – she is only thirty-seven years old at this date.

Another re-blog. I came across this recently while looking through my computer files. I want to re-blog it in memory of Jean Hughes, an incredibly gifted islander, who was directly influential in the lives of so many island children and those in need. She was the Coffin School Trustee’s President for many years and I had the honor to serve as a trustee under her. She passed away in the summer of 2025. Jeanie loaned me this from her family collections as she thought I would enjoy it. She knew me better than I thought she did. With love. 1830s Chinese silk to be exact. It literally floated into my lap as I sat reading a letter.  A letter from a young Nantucket girl to her grandparents. A young girl who just several years before had moved from tiny Nantucket Island to San Francisco with her mother to join her father. He had moved for better work and a better life. Nantucket was in an economic decline. Reading this treasure trove of letters – loaned to me by a friend who is a descendant of these people I mention – was like spying on them. Now, when I read Mitchell family letters and writing it is slightly different for me. Having worked in the Mitchell House for so long, I feel like they are a part of my family. This batch of letters was different however. I felt like they know I read their letters – as if they were looking over my shoulder or sitting on the other side of the room aghast. I felt like they thought no one ever would – or at the very least an outsider – read this correspondence. The worse letter one was the son writing to his mother upon receipt of her letter telling him of his father’s death. That was hard. Made harder because he thought his father was fine – he was as of the last letter a month or two before. Made harder as I lost my own Father a little over a year ago. I knew how he felt – but cannot imagine receiving a letter that is about a month old telling one of such horrible news. He had not seen his father in several years. I could speak to my Father, visited him monthly, and was there with him. That was not an easy letter to read. The silk fabric piece is quite beautiful – and still pristine – as if it was just folded into the letter yesterday. She wanted to share with her grandparents the dress that her cousin had brought to her directly from Hong Kong. A cousin, who was likely pregnant – or “sick” as was written but it was obvious what “sick” meant (yes, pregnancy was looked at as an illness in a way – and there were high rates of infant and mother mortality during and immediately following birth). The cousin had travelled back and forth to Hong Kong on the China Trade with her husband it seems but due to the pregnancy had to be put off with family or others until the baby was born. This was a common practice for the wives of whale captains who might go to sea with their husbands. They were put off with other whaling families or missionaries in far off ports so that they could have their baby where others could help. Sometimes they were put off months in advance. And, did you know that Nantucket whale wives were the FIRST to go to sea with their captains husbands? They set the trend – after all, we were the whaling capital of the world. At least, until we lost that title for multiple reasons. I digress. The other piece that leads one to realize that money was to be had – at least for the cousin – is that she didn’t bring fabric – she brought the dress already made in Hong Kong. Yes, it would have been less costly there than in the United States but it shows there was extra money for spending. And, there was enough excess fabric inside the dress for this young girl to cut off a piece of it and send it to her grandparents. Making them feel as if they were a part of her daily life – and making her feel that way too. So far from home. On the other side of the continent with Nantucket Sound in the midst, to boot. JNLF
