Nantucket Maria Mitchell Association Welcomes Dr. McKinley Brumback as Featured Guest for October Science Speaker Series

October 4, 2023

Nantucket, MA – The Nantucket Maria Mitchell Association (MMA) announces that it will host Dr. McKinley Brumback, as a featured presenter for its October Science Speaker Series. Her presentation will take place on Wednesday, October 25 at 7pm. It will be presented via Zoom. This event is free to all.


“Using X-Rays to Probe the Universe’s Strongest Magnetic Fields”


High energy astrophysics tests our understanding of fundamental physics in the most extreme environments in the Universe. Among these are neutron stars, which host the Universe’s most powerful magnetic fields. These fields are impossible to reproduce in Earth-based laboratories, but observational astrophysics offers a direct way to investigate these environments. Dr. Brumback works with systems called X-ray binaries, in which gas donated by a stellar companion moves towards the neutron star and becomes increasingly hot until it emits X-rays. Eventually, the magnetic force becomes much stronger than the gravitational force and the gas is funneled onto the magnetic poles of the neutron star. Brumback is interested in studying the shape and movement of gas in this region, where the gas flow transitions from gravitationally dominated to magnetically dominated. By using X-ray observations from different NASA missions, these regions can be studied and the shape of the gas as it moves around the neutron star can be mapped.


Professor McKinley Brumback is an astronomer who studies X-rays coming from some of the most energetic and extreme environments in the Universe. She uses observations from NASA and ESA X-ray

observatories to investigate how matter behaves close to neutron stars, the ultra-dense and magnetic objects left behind by massive stars. Brumback is an Assistant Professor in the Department of Physics at Middlebury College in Middlebury, Vermont. She completed her PhD in Physics and Astronomy at Dartmouth College in 2020. After graduation, she continued her X-ray astronomy research with postdoctoral positions at the California Institute of Technology and the University of Michigan.

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.

The Ancient Vine

By Jascin N. Leonardo Finger • May 27, 2025
This is what our landscaper for 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 this 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 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 19, 2025
May 27. {1857} There is this great difference between Niagara and other wonders of the world, that is you get no idea from descriptions or even from paintings. Of the Mammoth Cave you have a conception from what you are told, of the Natural Bridge you get really a truthful impression from a picture. But Cave and Bridge are in still life, Niagara is all activity and change. No picture gives you the varying form of the water of the change of color; no description conveys to your mind the ceaseless roar. So too the ocean must be unrepresentable to those who have not looked upon it. Maria Mitchell would tour the Mammoth Cave and the Natural Bridge during her trip to the southern United States as Prudence Swift’s chaperone – I have written of these travels and Prudence before. Niagara Falls is a place she likely saw on her way to visit her younger sister Phebe Mitchell Kendall, who once lived with her husband in Pennsylvania. I was a bit surprised that she feels the way she does about the Cave and Bridge being well-represented by images but I do kind of se her point. But Niagara, the ocean, any moving body of water – she is right. You don’t fully comprehend it until you hear it, touch and taste it, see its colors, and feel it splash, sprinkle, or mist across your face. Niagara certainly mists across your face – sort of like a breezy day at the beach and the salt mist that slowly builds across your face and coats the beach grass so that it shimmers in the sunlight.

Lily of the Valley

By Jascin N. Leonardo Finger • May 12, 2025
I have been watching it. Waiting. Today, I was rewarded with the scent as they have now started to open. From late fall, all through the winter and early spring, there is a very large patch of dirt with traces of roots and purple-like portions of some sort of plant. Then, they slowly start to send their shoots forth – up from that dusty pile of dirt come little greenish pips that become the leaves. Then, you start to see the stems tightened against the leaves and then lovely chartreuse buds are visible that then turn to white and slowly open from top to bottom. As soon as they star to open, I wait. Knowing that one morning I will walk by soon and then I will get a delicious waft of Lily of the Valley. I have written about this patch at the Mitchell House before. I have always been fascinated by the fact that these grow in full sun – they have no shade whatsoever. And this patch is old. I’m not sure how old – I do not think late nineteenth century but possibly – or maybe very early twentieth century. We have one or two images in the collection from the early 1900s but one does not show the ground, and the other not so much either. I also think this is one of the earliest flowering patches of Lily of the Valley on island – let me know if you’ve seen others this early. And in FULL sun to boot! But in any case, today was the day – May 5, 2025 – that I got the first waft. Saturday when I was here, they were not ready yet. But now, they are! And when I smell it, I know why it was my mother-in-law’s favorite flower. JNLF
