Nantucket Maria Mitchell Association Astronomers Travelled to Largest Ground-based Optical Telescope in the World for Research

January 30, 2024

NANTUCKET, MA — Last December, the MMA astronomers travelled to the site of the largest ground-based optical telescopes in the world, the Keck Observatory, located on the Big Island of Hawai’i.  The MMA’s National Science Foundation (NSF) astronomy post-baccalaureate research fellows, Emmy Wisz and August Muller, travelled to Keck to obtain observations of distant galaxies for their research projects focused on unraveling the mysteries of the universe. 

 

Located at nearly 14,000 feet elevation near the summit of Mauna Kea, Keck is accessed remotely by astronomers around the world who operate the telescopes’ scientific instruments and collect astronomical data. The 10-meter telescopes are essential tools for many research projects, so groups must participate in a competitive process of proposal submission to secure observing time.  Because of the effects of potentially severe altitude sickness, astronomers observe from the base of the mountain  ̶  at Keck Headquarters in Waimea. Over the course of each night, astronomers operate the instruments from the remote operations room at Keck Headquarters, while being in continual contact with the telescope operators who are located on the summit.   

 

Wisz and Muller joined in on observations as part of two international collaborations that were co-founded by the MMA’s Director of Astronomy, Dr. Regina Jorgenson, and supported by grants from the NSF).  The first collaboration, called the Fast and Fortunate for FRB Follow-up, or F4 Collaboration, is using the Keck telescopes in an effort to probe the cosmic web, to understand what makes up the space between galaxies, and to identify the progenitors of the still mysterious fast radio bursts – extremely energetic and brief flashes of radio radiation.  The second collaboration, called the Multi-wavelength Analysis of Neutral Gas Observed in Emission and Spectroscopy, or MANGOES Collaboration, is utilizing the cutting-edge astronomical technology on the largest telescopes in the world to detect and study the elusive “baby galaxies” – those forming just a few billion years after the Big Bang.   

 

While at Keck, Wisz and Muller met several of the collaborations’ members, including Prof. J. Xavier Prochaska of the University of California, Santa Cruz and Dr. Marc Rafelski of the Space Telescope Science Institute, and learned first-hand how to conduct observations with Keck’s cutting-edge instruments.   

 

When asked to describe their experience participating in the observing run, and what it was like to travel to the Keck telescopes, post-baccalaureate research fellow Emmy Wisz stated, “I feel incredibly lucky to have been able to be so intimately involved in this process for four nights, especially as a junior astronomer. I am especially lucky that three of the four nights I was involved in were clear with no major weather issues! There is incredible value in seeing how the telescopes and instruments work in real-time and watching the data be read out after each exposure.” 

 

August Muller added, “Keck is an optical telescope, which means that most of the light measured is that which we can see with our eyes. While some other types of telescopes (especially those observing radio) can operate all day long, optical telescopes really do need to be used only at night. Nothing has made me feel more like an astronomer than the experience of working all night and sleeping once the sun rises in the morning.” 


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.

From The Rear

By Jascin N. Leonardo Finger • November 3, 2025
I am not so sure our founders would love that title but the image is of the Maria Mitchell Vestal Street Observatory (MMO) “from the rear.” I love this image as it is really the only one we have – unless you count the one that is taken from farther away and from further into the backyard of the Mitchell House. That one allows you to see the natural slope of the Mitchell House back lawn which would be altered when they added the Curator’s Cottage. Both of the images were taken before the Curator’s Cottage was added at the back of the Mitchell House in the early 1930s – and this one you see here was taken before 1922 when they added the Astronomical Study onto the MMO. It also shows the original dome – which was copper – before it was replaced in 1951 – which is the current dome. The copper did not hold up to our climate here – salt spray, damp, fog. But the new one, shipped over from England, has held up well. The current dome was donated by Margaret Underwood Davis (MMA board president at the time), in memory of her son, Cushing Davis who was an amateur astronomer. Margaret Davis served as president from 1930-1946 and again from 1949-1953. The image tells you some other things too. For instance, the grape arbor behind the Mitchell House is supposed to be Peleg Mitchell’s (Maria’s uncle) grape vine – I have blogged about it several times before – and you can see it in this image. You can also see how the Milk Room connects to the 1850s kitchen. The 1850s kitchen was added by Peleg Mitchell Jr and it’s the first little wart you see with the white pipe attached. The next wart is the Milk Room – also added by Peleg – it’s the one with the shutters on the window. Both still exist it’s just the Curator’s Cottage was attached in the 1930s. You will see another chimney too. It appears alongside the white pipe. That is likely the original chimney to what is now the Astronomer’s Cottage at the MMA. We acquired the Cottage in the 1920s but I believe all of the additions, and the removal of the chimney, were done before we were given it.  Fun! JNLF

Stone Monument Cleaning

By Jascin N. Leonardo Finger • October 27, 2025
I have discussed the process and importance of the proper cleaning and conservation of historic stone monuments – cemetery stones – several times before in this blog. This year’s Mitchell House intern, Talia, was also (happily) last year’s intern and due to her college graduation in early June, she missed the annual workshop I have been running concerning the proper care and cleaning of stone monuments. A stone monument enthusiast, I promised Talia we would clean a stone before she left this season. Happily, we did on September 26. We returned together to clean the stone of Charlotte Burdett, Captain of Barzillai Burdett, one of my favorites. I had come across his stone accidentally when prepping to clean another stone for the workshop in June. (I test stones about a month before I clean them to make sure the cleaner will be okay and there are not any issues with it among other things I check for.) I tested the two Burdett stones and after the workshop was over, I remained in the now fairly hard rain showers to clean his stone. At that point, I was sopping wet and I told Charlotte I would return. I always feel badly when I have to return months, or a year, later to complete the stones in a lot. We made fast work of Charlotte’s stone – a little under an hour but the Burdetts’ stones are relatively small and simple. It was also a beautiful day to complete the work. The remainder of this blog will be a bit long because I wanted to share some information on Captain Burdett. He and Charlotte had no children and I have long loved their simple, small gambrel house on North Liberty (not likely a gambrel when they inhabited it). So here we go. In the history of catboats on the island, the Dauntless is my favorite catboat, likely because the owner/captain is a Nantucket “rockstar” of mine. His small gambrel roofed house still stands along North Liberty – a favorite house of mine before I learned a “rock star” inhabited it! The Dauntless was sometimes referred to as the “star boat” because a large red star was sewn on her sail. Built and captained by boatbuilder, Captain Barzillai Burdett, the Dauntless took visitors from the wharves out to the bathing beaches and on clambakes and fishing excursions, beginning in the early 1870s. Two logs of the Dauntless attest to her being a busy boat, enjoyed not only by the passengers, but by her crew as well. The logs live at the Research Library at the Nantucket Historical Association (NHA). At least one was kept by Benjamin Sharp. When he was young, he served aboard the Dauntless with Captain Burdett. Sharp would become a revered island resident. Born in 1858, Dr. Sharp, a zoologist, was a founder of the Nantucket Cottage Hospital, served as Nantucket’s representative in the state legislature, and was an avid sailor and fisherman. In 1904, with Henry W. Fowler, he wrote T he Fishes of Nantucket . Times spent with Captain Burdett must have greatly influenced Sharp. One of the logs dates from July 2 through August 28, 1873, and is a daily record of fishing parties and clambakes the Dauntless provided. The log also includes the names of passengers and where they came from, as well as messages they left for Captain Burdett. Included in the log is this poem: When you go to a clambake, Plenty of chickens you should take, As then you have a second dish For those who do not like shell-fish, For all should indulge, as best they might, “The keen demands of appetite.” The log also has lots of wonderful, comical illustrations − largely drawn by Sharp. Burdett also built whaleboats during the heyday of whaling on the island. Fishing was also his economic mainstay. When summer was over, he would use the Dauntless to fish as many other catboat owners did. The tourist trade had come second to fishing and whaling on the island but, in many cases, may have made fishing secondary in income once tourism took off on island and became much more lucrative. In 1893, artist Elizabeth Rebecca Coffin (a distant cousin of Maria Mitchell’s and one of her students at Vassar), painted a lovely double portrait of Burdett and Benjamin Pease in Burdett’s shack on Old North Wharf called “A Tale of the Sea (Captain Burdett In His Boathouse).” Today, it is in the collection of the NHA. PLEASE NOTE: ONE SHOULD NEVER CLEAN THE STONES IN A CEMETERY, WHETHER THEY ARE YOUR FAMILY’S OR NOT, WITHOUT PERMISSION FROM THE CEMETERY SEXTANT AND HAVING BEEN TRAINED TO PROPERLY CLEAN A STONE. There are quite a few TikToks and other social media posts and people are doing the work incorrectly and damaging and further eroding the stones. JNLF
