Recap of the Maria Mitchell Association at the 237th Meeting of the American Astronomical Society

Regina Jorgenson • February 2, 2021

The Nantucket Maria Mitchell Association is proud to recognize and congratulate its six summer 2020 National Science Foundation Research Experiences for Undergraduates (NSF-REU) interns (virtual for 2020) for their wonderful job presenting their research at the recent meeting of the American Astronomical Society (AAS). The 237th meeting of the AAS took place on January 11-15, 2021 and in light of the COVID-19 Pandemic, the meeting was held virtually. Over 3,000 astronomers from around the world came together to network and share the news of their latest discoveries. As is customary, the Maria Mitchell Observatory (MMO) brought its six NSF-REU interns to the meeting to present their summer research findings. In a continuation of the long tradition of excellence in research and mentoring at the Maria Mitchell Observatory, each intern presented their work, covering a range of topics from exoplanets and X-ray studies of stars, to seeking out the missing matter in the Universe and understanding how black holes devour stars that wander too close. Each intern presented their research in the format of an iPoster (interactive poster) as well as a five-minute talk followed by questions. The interns did an exceptional job and the Maria Mitchell Association is proud to be represented by such an astounding group of young researchers! A complete list of all of the MMO intern presentations follows below. 

 

Other highlights from the meeting included: a new exoplanet confirmed orbiting around a triple star system; a rocky planet found orbiting a very old star; the discovery that the disk of our own Milky Way Galaxy is warped; a new effort to use distant pulsars as ultra-precise clocks to measure the generalized gravitational wave background; and the discovery of the most distant quasar yet observed. For more on this last story, listen to Dr. Jorgenson’s interview on WCAI’s Looking Skyward (https://www.capeandislands.org/post/looking-skyward-most-distant-quasar). In addition, there were multiple interesting panels and discussions on equity, inclusion, and diversity efforts, many of them emphasizing and demonstrating the impact that programs such as the MMO’s NSF-REU and post-bac fellowship programs are having on increasing, supporting, and retaining underrepresented groups in astronomy. 

 

The following is a complete list of the MMO’s REU intern presentations:

 

  • Sharpening NuSTAR X-ray Images of Pulsar Wind Nebula G21.5-0.9
  • Devon Barros (Bridgewater State University)

 

  • First Millimeter Flares Detected From Epsilon Eridani With ALMA
  • Kiana Burton (Temple University)

 

  • Search for X-rays from RV Tau Variable Stars
  • Sarah Graber (Columbia University)

 

  • Using TESS Data to Search for Transiting Exoplanets Around White Dwarfs
  • Alex Granados (Wellesley University)

 

  • Untangling the Cosmic Web: VLT/MUSE Observations of FRB Host Galaxy 180924

The Ice Man Cometh

By Jascin N. Leonardo Finger • August 10, 2026
This is a blog of the past. I often think of this “story” when it’s hot and humid out. So here it is again. The past few weeks have been very un-Nantucket as far as the heat and the extreme humidity. When I was a child and even a teenager, I remember that we always wore long pants and even sweaters in the summer evenings on island. This does not seem to be the norm any longer unfortunately. The heat also leads me to think about staying cool and what generations before us did to preserve food. Long before modern refrigeration, ice was used for preserving foods. Although the use of ice brought an end to salting and drying fish for local markets, with railroad development and western expansion in the 1850s, salt fish was still being shipped to inland domestic markets as well as abroad. As the fishing industry grew on Nantucket and elsewhere, however, so did the need for ice to keep the catch fresh for market. On Nantucket, when a hard freeze produced ice of the necessary thickness, blocks were cut from Maxcey’s and Washing Ponds and the North Head of Hummock Pond and stored in nearby icehouses. This was a fairly long and tricky process that took skill to make sure the ice was the right thickness and that one did not fall through the ice. Mainland icehouses typically used sawdust for insulation, but Nantucket ice was insulated with beach grass, seaweed, and eelgrass—sawdust not being readily available here. The iceman would drive his cart around the streets with usually a gaggle of children trailing behind – or hitching a secretive ride on the back of the cart – hoping for a piece of ice to suck on and cool off with – back when something that simple was a pure delicacy. When electricity was introduced on Nantucket in 1889, cutting pond ice was no longer necessary. Captain John “Jack” Killen built the first ice-making plant, on Straight Wharf, opening it on May 5, 1902. Several other plants, including that of the Island Service Company, followed—all operating until the Great Depression. Nantucket’s early ice-making plants were established primarily for packing fish and shellfish, which were shipped in barrels or fish boxes layered with ice. Fishermen both on and off-island would stock up on ice before going out on long trips, and it is said that island ice was of a much higher quality than that from plants off-island—perhaps because of the purity of Nantucket’s water. Some people still cut ice. My parents had an elderly friend, now gone, and his family owned – and I assume still owns – a camp of cottages from the 19 th century up in New Hampshire. In the winter, the entire family shows up to harvest ice and store it in the icehouse. The ice is then used in each of the cottages during the summer since they have no electricity or plumbing. It is an art that is almost gone but happily there are still a few who have passed down the knowledge and skill for harvesting ice. I recently took a look at his obituary and was blown away – I remember him for ice harvesting – but wow what a life! One of service and seeking justice. JNLF

Nantucket Maria Mitchell Association Announces Seventh Annual Green Crab Week

July 28, 2026
NANTUCKET, MA— Join the Nantucket Maria Mitchell Association (MMA), Nantucket Land and Water Council (NLC), and Sustainable Nantucket (SN) for the Seventh Annual Nantucket Green Crab Week! The MMA, NLC, and SN will be offering fun daily events from Monday, August 3 to Saturday, August 8 to learn about, and take action against, invasive European green crabs on Nantucket. European green crabs were first introduced to North America in the 1800s, likely traveling in the ballast water of merchant ships from Europe. This invasive species is now abundant on Nantucket, threatening crucial aquatic resources, including eelgrass beds, shellfish populations, and native crab communities. Together, as a community, it is possible to help prevent green crabs from destroying the natural resources that make Nantucket’s waters so special! Please come join us during Nantucket Green Crab Week to learn more.

Sustainable Nantucket is a nonprofit organization dedicated to strengthening Nantucket’s local food system and building a more sustainable island community. Through education, advocacy, and community programs, the organization supports local farmers and producers, increases access to locally grown food, and connects the community with Nantucket’s agricultural resources. The Nantucket Land & Water Council is a nonprofit organization dedicated to protecting Nantucket’s land, water, and natural resources. Through conservation, research, education, and advocacy, the organization works to preserve open spaces, protect water quality, and ensure the long-term environmental health of Nantucket for future generations. 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. ####
