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

April 28, 2023

Nantucket, MA – In mid-April, Nantucket Maria Mitchell Association (MMA) astronomers traveled to the site of the largest ground-based optical telescope telescopes in the world, the Keck Observatory located on the Big Island of Hawai’i. MMA’s National Science Foundation (NSF) astronomy post-baccalaureate research fellows, Fiona Powers Özyurt and Michele Woodland, traveled to use the famous Keck telescopes for an ‘observing run’ - astronomer lingo for the process of obtaining scientific data with a telescope - for their research projects studying the universe.
 

The Keck Observatory is located at nearly 14,000 feet elevation near the summit of Mauna Kea but 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. Powers Özyurt and Woodland joined in on this most recent observing run as part of the Fast and Fortunate for FRB Follow-up (F4) Collaboration, founded by Maria Mitchell Association’s Director of Astronomy, Dr. Regina Jorgenson and her collaborators and funded by a competitive grant from the National Science Foundation. The 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 observing run went great,” shared Woodland. “Although we ran into several hiccups, like discovering the bottom shutter of the dome was broken so we could only view targets above a certain elevation, we were able to adapt quickly and change our schedule accordingly. During our observing run at Keck we obtained spectra of multiple different Fast Radio Burst host galaxies located a few billion light years away,” she continued. “A lot of the work that I do involves reducing data from big telescopes like Keck. This opportunity gave me the chance to understand and appreciate the intricacies of acquiring the data that I then reduce. There are so many tiny little steps that go into it, and it is so easy to mess up. I have a lot of respect for people who do this often.” 

 

In the month before heading to Hawai’i, both Woodland and Powers Özyurt contributed to the planning of the observing run, learning about the instrument, assessing the suitability of various targets, and creating detailed plans for each night. During the two night observing run, they were responsible for operating the instrument, taking the data, and ensuring that all of the required calibrations were taken. They were also responsible for communicating with the Keck Observatory support staff who operate the telescope and maintaining communications with the rest of the observing team, some tuning in remotely via Zoom. Fortunately, all of their hard work and preparation paid off, the weather cooperated on both nights of the observing run, and the team collected data on all of their desired targets. 

 

Powers Özyurt said “It was surreal to be driving the instrument in person….We were able to collect a variety of imaging and spectral data in support of the F4 Collaboration.” She continued, “For observational astronomers, getting observing time on large ground-based telescopes is a very competitive process, so we try to make the most of our allotted time by creating observing plans where every minute counts.”

 

Both Powers Özyurt and Woodland shared that the experience of traveling to the telescope and experiencing the observing process up close and in person was invaluable. 

 

“This experience was definitely a dream come true for me,” said Powers Özyurt. “One of my favorite parts of astronomy is observing, and being able to observe with the largest optical and infrared telescope telescopes in the world was definitely high up there on my bucket list! It can be fun to reduce, analyze and make conclusions from your data after it has been collected, but seeing your data be collected in real time and having complete command over every aspect of the instrument is unmatched.” 

 

Woodland summarized the observing run as follows: “Being in person at Keck headquarters was an amazing experience. I got to meet so many people and build so many important connections. This experience has made me very excited for what is to come in my career in astronomy.”
 

The Nantucket Maria Mitchell Association (MMA) 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.

A Good Chair

By Jascin N. Leonardo Finger • May 18, 2026
A repost from long ago – because I still like a good chair. Quite awhile ago, I wrote about some of my collection addictions, including pottery shards, 19 th century kitchen mirrors, and of course, enamelware. Well, here is another one for you. I love chairs. Yes, this is another collection addiction of mine. But not all chairs – chairs from the eighteenth and nineteenth centuries. Typically, I like plain, simple wood chairs with a horizontal piece or two of wood for the back and a plain, thick wood seat. Simple, not a lot of turns to the wood, and not a lot of decorative features or paint. Several years ago, I had a meeting at the home of the leader of a group I was working with. She owned the Obed Macy house, very much untouched and quite a remarkable house. Yes, Obed was the Nantucket historian (among other things), as well as the son of island entrepreneur Judith Macy, and the nephew of the island “she-pirate” Kezia Coffin. We met outside on the side porch which was a late 19 th century addition to the house and one that certainly reflected what life was like in the period it was added to the house. The owner had brought out every chair in her home. I was on a chair high (not a highchair!) – here I had my choice of nineteenth chairs to sit on. Since I was one of the first to arrive, I took my time picking out which chair I was going to sit on – I kid you not. I was like Goldilocks − though I was grown-up enough not to sit on every chair to decide which one I was going to claim for the meeting! I went on and on and likely on and on about all these lovely chairs to her. Unfortunately, the day came several years later when she was faced with having to sell her beloved home to move off-island. She called me. She wanted to know if I wanted any of her chairs since she remembered how much I went on and on about them. It was a mixture of emotion because losing this island resident was a loss for the island and for its history and historic architecture. I went to her home a few days before she was going to have her sale and helped her move items from the house out onto the lovely 19 th century side porch where I first reveled in her chair collection and also out into the large, simple backyard that looked like it too had not been touched since the 19 th century. She told me to take whichever chairs I wanted as she wanted me to have them. Depressing. I told her I would not take but that I would buy. We had a little back and forth but she finally relented. Then, I had to choose and it was quite agonizing. Not wanting to be a chair hog, I limited myself. I now have two matching and two others sitting around my dining room table made from salvaged Nantucket pine floorboards. We refer to them as “Helen’s chairs” – their previous owner. She likely found them here on Nantucket; one or more may have even come with the house when she bought it. We eat every meal sitting in them, spend time with our family in long discussions and laughter sitting in them, and each time I sit, touch, dust, or move them, I think of Helen and the house these chairs once sat in and the conversations and people they must have witnessed over the many years. A simple wood chair – a witness to history and time. JNLF

The Ancient Vine

By Jascin N. Leonardo Finger • May 11, 2026
A repost – with my apologies – from last year. It started budding the week of April 30 this year. This is what our landscaper for the MMA calls it. “The ancient vine.” He tells the people who work for him not to touch the “ancient vine.” I have probably made him – and all of them – terrified of it. I am even terrified of it to some degree. I refer to the grape vine behind the Mitchell House that is supposed to be Peleg Mitchell Junior’s grape vine – Maria Mitchell’s uncle who inhabited the house from about 1836 to his death in 1882. It has two trunks but one died several years ago. Because of that, each year I try to root shoots. It’s fairly easy to do – when you cut back the vine in late fall/early winter. I have had success but not success protecting the shoots I baby all winter from bunnies and other critters once I plant them – try as I might. I started doing this when the one trunk died – I was PANICKED! The landscaper stays away because I have told him if anyone is going to accidentally harm or worse yet, kill, this grape vine it would be me so I only have myself to blame. So each November/December – once ALL the leaves have fallen off – I climb my ladder and quietly, carefully, and fearfully cut back the stems typically to two buds. I have been somewhat successful in spurring grape production – and these grapes attract some amazing birds in the fall. It takes me some time – and I pretty much hyperventilate the entire time – and then, I stare at it all winter. Passing under it multiple times a day to reach my office. Hoping, and yes, praying, it will come out in the spring. It’s a late budder so just recently the buds started to show themselves – thank goodness! – and I was rewarded today (May 5, 2025) with this wonderful hot pink color on the edges of the leaves as they are uncurling.

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • May 4, 2026
May 6, 1878 Between the clouds, Miss Spalding obtained 7 photographs of Mercury on the Sun. It is comfort to me to be able to plan and do a new kind of work. The large telescope worked better than usual, Clark having just been to the Observatory. Clark, as in Alvan Clark, a man who would become the premier telescope maker in America and who built Maria Mitchell’s 5-inch Alvan Clark refractor that she purchased from him (after working with him to build it per her specifications) with money gifted to her from “The Women of America” led by Elizabeth Peabody. More than likely, it is this telescope she is referring to as she did use it in the Vassar College Observatory with her students – and it is also taking center stage in photographs, along with her (first her father’s) Dolland telescope.  Maria had decided she would photograph the Sun on every clear day, and this was one of those results. She would use these images, with her students, to study sun spots and their changes. With her students, Maria would photograph the transit of Mercury as noted above. She would also photograph the transit of Venus a few years later with her students. JNLF
