Nantucket Maria Mitchell Association Welcomes MMA Post-Baccalaureate Research Fellows Pop-Up Science Talk

November 16, 2023

NANTUCKET, MA — The Nantucket Maria Mitchell Association (MMA) announces that it will host the MMA’s National Science Foundation Post-Baccalaureate Research Fellows, Emmy Wisz and August Muller, for a pop-up science talk concerning their research. People may know them from Open Nights at Loines Observatory and their weekly Star Reports. Their pop-up science talk, “In a Galaxy Far, Far Away: Spectral Analyses of Distant Galaxies,” will take place on Monday, December 4 at 4:30pm EST. It will be presented in person at the MMA’s Research Center, 4 Vestal Street, or online via Zoom. This presentation is free to all.


How do we learn about galaxies a billion light years away? How do we learn about the history of our own home galaxy, the Milky Way? By using spectral analysis, as well as other techniques, we can gain insight into the chemical composition of faraway galaxies and their environments, creating a roadmap to understand how galaxies form and evolve over time. Emission from galaxies reveals properties of the local galactic environment, such as the star formation rate and age. Absorption features provide a peek into regions of the galactic environment that are rich in gas and home to the elements necessary for star formation. Focused on a type of galaxy called a damped Lyman-alpha system, or DLA for short, Emmy Wisz will explain how we use bright background sources as lighthouses to learn about galaxies that are too distant to be seen directly. By investigating the home galaxies of the still-mysterious fast radio bursts, August Muller will discuss how these strange bursts may come to be and how we are using them to probe the distant Universe.


Emmy Wisz obtained her B.A. in Astronomy and Physics from Bryn Mawr College. Her undergraduate research focused on galaxy formation and evolution, studying the impacts of morphology on radial metallicity gradients. She is excited to continue to be involved in the field of galaxy evolution, researching damped Lyman-ɑ (DLA) systems to expand on her understanding of the formation of galaxies over time.


August Muller holds a B.S. in Physics from Haverford College. Her undergraduate thesis investigated techniques for detecting extreme mass-ratio inspiral gravitational wave signals for the upcoming LISA gravitational wave detector. During her year on Nantucket, August is excited to learn more about observational astronomy as she investigates the host galaxies of fast radio bursts.


Join Emmy Wisz and August Muller for this Pop-Up Talk in person or on Zoom. Pre-registration is required for Zoom.

The Maria Mitchell Association 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.

[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
