Rachel Bowyer to Speak as Featured Guest for Nantucket Maria Mitchell Association’s Science Speaker Series

Website Editor • March 24, 2021

Update: Due to unforeseen circumstances, we are rescheduling the Wednesday, March 24 Winter Science Speaker Series talk. The new date will be Wednesday, March 31 at 7pm. The registration link for the event remains unchanged.


On March 31st at 7pm, the Nantucket Maria Mitchell Association (MMA) is hosting a live lecture entitled, “Hidden Patterns in Galaxy Motions: What They Can Tell Us About the Universe” presented by former MMA National Science Foundation Research Experience for Undergraduates (NSF-REU) intern, Rachel Bowyer. This talk is part of our FREE Winter Science Speaker Series and will be held via Zoom.


Galaxies move at hundreds of miles per second through space, yet they are so far away, that they appear stationary to us on Earth. However, recent advancements in observing techniques have made it possible to observe the motion of hundreds of thousands of galaxies all across the sky. These observations are revealing complex, streaming and swirling patterns in galaxy motions that are rich in information about our universe’s formation and evolution. Specifically, these motions can tell us about the formation of structure in the universe and about primordial gravitational waves. In this talk, Bowyer will discuss the emerging field of “real-time cosmology” and how patterns in galaxy motions can be used to study the early universe.

 

Bowyer is an Astrophysics graduate student working towards her Ph.D. at the University of Colorado, Boulder. She researches cosmology and the early universe, specifically, what observed galaxy motions can tell us about gravitational waves and the formation of structure in the universe. Recently, Bowyer was awarded the prestigious Chambliss Astronomy Achievement Award for the presentation of her work at the American Astronomical Society meeting. Bowyer began her research career at the Maria Mitchell Observatory in the summer of 2017. At the MMO, she worked on a project to map the dark matter structure in galaxy clusters using the effects of gravitational lensing. Aside from research, Bowyer enjoys undergraduate teaching and is interested in using the principles of Universal Design to develop accessible curriculum. Bowyer is committed to mentoring young scientists, and frequently serves as a mentor to women and minority undergraduates.

This series is organized by the Maria Mitchell Association, 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.

Mallow!

By Jascin Leonardo Finger • August 31, 2026
I’m sure you’ve seen it as you trek about the island – near the beaches and ponds. This image is of the swamp or marsh mallow that we have on Vestal Street in our garden out front of the Observatory. It can grow in drier places – though it’s not as lush as at Capaum Pond or out in Quaise. It’s in the Hibiscus family – and is fairly tropical looking and always a delight to see.  “When in bloom, one of the most showy plants of the Island, for a mass of the magnificent, large flowers on the edge of a blue pond causes one’s heart to thrill at the wealth of deep pink colour . . .” from Nantucket Wild Flowers, Alice O. Albertson (cousin of Maria Mitchell), 1921. JNLF

A Piece of a Clay Pipe

By Jascin N. Leonardo Finger • August 24, 2026
I have always wanted to find a piece of a clay pipe. I know – weird – but if you have ever read any of my blogs here for the MMA then you know I have a thing for pottery shards. I sort of figured I would not find a piece of a clay pipe – not even a piece of a stem. But the other day, walking in a place where I have found quite a few shards, I found a piece of clay pipe! Now, I’m not talking about water pipes – I am talking about tobacco pipes. And I know very little about clay pipes. Yes, I am a curator of a historic house museum, but this family did not smoke. They were Quaker and among the many things they abstained from, tobacco was one of them. Therefore, I am not up on clay pipes so I am doing a bit more research.  For one, age can be determined by the width of the hole inside the pipe. So based on this one, I would say it’s fairly late. Since they were so fragile, and those holes pretty small, if it got filled with tobacco, the person just broke off the stem creating a shorter pipe and one that was not clogged with tobacco. Apparently, stems could be recycled – in fact, 15,000 broken stem pieces were uncovered at a historic walkway at Colonial Williamsburg – they were used as fill! And pipes were made into the early twentieth century – falling out of favor around World War One. It makes sense – they were cheap, easy to make, and affordable. Typically, one could last a few years – unless you dropped it of course. An,d pipes were used by men, women, and (eh, em) yes, children. I can see that Nantucket may not have had a lot of tobacco smoking residents – not just that some were Quaker – but because of the Quaker influence. I t does not mean people here do not smoke – I just think there may have been fewer smokers on the island in the nineteenth century and earlier. JNLF

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • August 17, 2026
August 19 {1857}. There are four great men whose haunts I mean to seek, and on whose footsteps I mean to stand: Newton, Shakespeare, Milton, and Johnson. To-day I told the driver to take me to St. Martin’s, where the guide-book says that Newton lived. He put me down at the Newton Hotel, but I looked in vain to its top to see anything like an observatory. I went into a wine-shop near, and asked a girl, who was pouring out a dram, in which house Newton lived. She pointed, not to the hotel, but to the house next to a church, and said, “that’s it – don’t you see a place on the top? That’s where he used to study nights.” It is a little, oblong-shaped observatory, built apparently of wood, and blackened by age . . . .” Blackened no doubt by the wood ash and soot found in the air throughout over-crowded nineteenth century London. We always think about London being very foggy in the nineteenth century but frankly a lot of it was wood and coal ash as the nineteenth century grew older, particularly as factories developed and belched all of that into the air – think Sherlock Holmes in the 1880s. But Maria Mitchell, while starting in Europe as a young woman’s chaperone, also knew that this tour of Europe was a great learning experience – the equivalent of a college education she could not have. Doors were thrown open to her around Europe – in particular at all of the observatories that dotted the continent. She was not just well-known – she was famous. JNLF
