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.

Happy 207th Birthday, Maria Mitchell!

By Jascin N. Leonardo Finger • July 28, 2025
August 1, 2025 marks Maria Mitchell’s 207 th Birthday! Since just about the founding of the Maria Mitchell Association – way back in 1902 – the MMA has hosted some celebration or marked the occasion of our namesake’s birth. From 3-5PM FRIDAY, AUGUST 1, 2025 , Vestal Street will be close to traffic and our Vestal Street properties will be open free to the public. We will have activities, games, art projects, live music with Susan Berman and Ray Saunders, and refreshments will be served. So, stop by and say hello! JNLF P.S. If we actually get rain, we will move our celebration to Saturday, August 2 - so keep your ears out! We will decide Wednesday.

Margaret Harwood

By Jascin N. Leonardo Finger • July 21, 2025
The MMA found its first astronomer in Margaret Harwood, a 1907 Radcliffe graduate who worked in the Harvard Observatory. Her fellowship began in 1912 and over the first year, she researched, continued to conduct public lectures and open nights, and worked with students of all ages – including those in the public schools. She returned to Cambridge for the winter months where she continued to work at the Observatory. In 1915, she took her leave as was authorized by the fellowship and acquired her master’s degree in astronomy at Berkeley. She returned to Nantucket in 1916, accepting the position of Director of the Observatory. This made Harwood the first woman to head a small private observatory in the United States. Harwood continued her research, with a focus on variable asteroids, published results of her work in numerous publications, and continued to lecture and host open nights. She had assistance from others, including island carpenter and school teacher, Alvin E. Paddock. Harwood became a “first –class celestial photographer . . . accumulating a valuable set of Nantucket photographic plates of variable stars . . .” which are still part of the MMA collection and were the first in the world to be completely digitized. Over the course of her tenure, more than 3,600 plates of the night sky were taken – more than 2,100 by Harwood herself. In the 1950s, Harwood was the first woman to gain access to the Mount Wilson Observatory then the world’s leading observatory, where she was able to use the photographic instruments to further her research. Harwood is seen in the photograph here as she looks for Venus during midday in the MMO using the Cooke-Clark telescope, guided by Maria Mitchell’s own Alvan Clark. JNLF

Nantucket Maria Mitchell Association Welcomes Kike Calvo as Featured July Presenter.

July 14, 2025
NANTUCKET, MA— The Nantucket Maria Mitchell Association (MMA) announces Kike Calvo, award-winning photographer, journalist, and author, as its featured presenter for its July Speaker Series. Calvo’s presentation, "The Power of Creativity: A Journey Through Storytelling, Exploration, and Hope," will take place on Wednesday, July 23 at 7pm at the Nantucket Atheneum’s Great Hall. This event is free. Join the MMA for an engaging evening with award-winning photographer, journalist, and author, Kike (Kee-Keh) Calvo. A Fellow of both the Explorers Club and the Royal Geographical Society, he has traveled to over 120 countries, photographing everything from belugas in the Arctic to traditional dances in Vanuatu. His work has been featured in National Geographic Magazine, The New York Times, Rolling Stone, and more. In this engaging presentation, Calvo explores how creativity can be a catalyst for connection, storytelling, and meaningful change. From documenting remote villages to diving with great white sharks, from defying the odds as an author to inspiring thousands of children in the Amazon, Calvo shares the invaluable lessons he has learned along the way. As a National Geographic Certified Educator and Safina Center Fellow (2020-2023), Calvo combines his passion for photography with teaching, having lectured at prestigious institutions such as Yale University. A pioneer in drone photography for art and conservation, he founded the “Little Explorer, Big World” initiative, which brings education to remote communities and has donated over 35,000 bilingual books. Described by anthropologist Wade Davis as, "a fresh voice in visual anthropology," Calvo has a gift for capturing the intersections of human existence. Calvo’s new book, Luminous: A Field Guide for Visual Explorers and Storytellers, isn’t just a book—it’s an invitation to slow down, look deeper, and photograph with soul. It’s a roadmap where photography meets presence, anthropology meets art, and storytelling becomes a path to connection.  Discover how creativity can illuminate pressing global issues—such as plastic pollution—and empower each of us to make a difference. This presentation is free and open to the public, graciously hosted for the MMA by the Nantucket Atheneum in the Great Hall. No registration required. About the Maria Mitchell Association: 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 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. ###
