Summary of the January 2023 American Astronomical Society Meeting

Dr. Regina Jorgenson • January 25, 2023

By: Dr. Regina Jorgenson, MMA Director of Astronomy


Earlier this month, MMA Astronomy interns, post-baccalaureate research fellows, Director of Astronomy, Dr. Regina Jorgenson, Executive Director, Joanna Roche, and Director of Science and Programming, Jónelle Gurley, traveled to Seattle, WA for the ‘Superbowl’ of the astronomy world, the American Astronomical Society (AAS) meeting. 


The AAS meeting is the largest annual gathering of professional astronomers, this year seeing over 3,000 astronomers come together to share news of their latest and greatest research results. Exciting new results were presented in all fields of astronomy, but the highlight of this meeting were the many amazing new results coming from NASA’s new Great Observatory, the James Webb Space Telescope (JWST), launched in December 2021. In addition to detecting and attempting to measure the atmosphere of the first Earth-like exoplanet, JWST is peering back into the early Universe farther than we’ve ever seen, giving us a glimpse at early star and galaxy formation. For a more detailed summary of the JWST results, listen to Dr. Jorgenson’s Looking Skyward interview here.


All six of the MMA’s summer 2022 National Science Foundation Research Experience for Undergraduates (NSF-REU) interns attended the meeting and presented posters describing their summer research. Presentation results spanned a broad range, from understanding how star spots can affect the overall brightness of a star, to how a nova explosion expands into its surroundings, to a new method for finding supermassive black holes getting kicked out of their galaxies. Other work attempted to use X-rays to understand the properties of interstellar dust, image some of the first galaxies forming in the early Universe, and use cosmological simulations to help us understand the largest structures in the universe, galaxy clusters. During their poster presentations, the NSF-REU interns spoke with top researchers in the field, allowing them to make scientific connections and act as ambassadors for all of the amazing research being done at the MMA. 


The annual MMA Alumni and Friends Breakfast was a highlight of the week, bringing together approximately 30 REU alumni, mentors, and friends. Connections were forged and stories were shared of long-ago summers spent studying the universe under the dark skies of Nantucket Island. 


MMA REU interns in attendance include: 

Kate Shavelle, MMA Astronomy intern and Columbia University student

Anavi Uppal, MMA Astronomy intern and Yale University student

Devisree Tallapaneni, MMA Astronomy intern and Cornell student

Will Jarvis, MMA Astronomy intern University of Wisconsin - Madison student

Chris Chang, MMA Astronomy intern and Willamette University student

Danya Alboslani, MMA Astronomy intern and University of Connecticut student

Top O’ the Ridge!

By Jascin N. Leonardo Finger • June 29, 2026
In April and early May, at long last, the Mitchell House roof was replaced. (I noted this in an earlier blog.) I had also noted that the roofwalk, given the condition it was in and its location – sitting on the ridge – had to be replaced. They had thought they could jack it up – as they have done with other walks – but the Blizzard of February 2026 that was ALL wind (83 MPH winds – read Category 1 Hurricane) and no real snow, made the walk impossible to treat in such a manner (read: crumble). So, after much discussion, review by our preservation easement holder, and permits, as well as some fundraising, we are replacing the roofwalk. The prior walk was not the original. The original blew off in a gale in the late nineteenth century, replaced at some point in the 1930s, and likely replaced again in the 1960s or 1970s. Then, since that time, it was heavily repaired. Its framing members were notched to accept the ridge boards (read: peak) of the roof and I think that may have been an original way to construct a walk. Makes perfect sense – and gives the walk more support and a lower profile. It was after all about putting out chimney fires and preventing roof fires. People copied what worked – and there have been a few others noted to be built in this manner still. It presents an issue though – because if you need to work on the ridge board or close to it – you cannot get to it easily – I guess you may be able to access it to some extent by lifting the deck boards of the walk. The new Mitchell House roofwalk will sit about six inches above the ridge – which will also allow air to circulate better over the ridge and the shakes in that area. That is the only thing that will really be different. It is protected by a preservation easement – as part of the Mitchell House’s easement – and frankly, even if we did not have an easement, we would not want it to look any different. So keep your eyes to the skies at 1 Vestal as we work to re-build the walk. With a special thank you to Barber and Sons and Lydon and Sons. JNLF

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • June 22, 2026
1875, June 20. A meeting of the Officers of Congress was called at the house of Mrs. Hanaford, 5 Summit Ave., Jersey City. The weather was intensely cold. I went to New York on the 19 th and stopped with my friend Mrs. Clapp, 100 W. 54 St . . . .It was a question who should preside. Mrs. Hanaford thought the Chairman of the Executive Committee should and I had been told that I should, etc. The question was decided by the non-arrival of the Chairman of Ex.Com. I called them to order at an hour after the time appointed. Of course I made many blunders, as I have never presided before, but I continued for 4 hours. We did a few good things . . . The thing most weighing on Maria’s mind at this meeting was the looseness of membership for the Congress. She felt people were not being vetted properly in some areas of the country and thus they may allow in “undesirables.” I would take this to mean women who were not entirely behind the cause of the Congress and the Association for the Advancement of Women. I am not surprised by her suspicions and likely she was correct – one could see naysayers gaining access to this group and trying to destroy it from the inside. The women’s rights movement would have many schisms within it as people disagreed and broke into smaller factions.  Another important thing to point out is that Mrs. Hanaford is Nantucket-born Phebe Coffin Hanaford. Raised a Quaker, like Maria, Coffin Hanaford would become the first woman Universalist minister in New England – among many other firsts. She grew up with Maria, attended and taught at the Coffin School here on Nantucket, and was a founding member of another women’s organization, Sorosis, which Maria was also a founding member of. It’s nice to see two sister Nantucketers continuing to work together as adults – far from home! JNLF

Pick A Picket

By Jascin N. Leonardo Finger • June 15, 2026
After many, many years of service, our picket fences are getting a much needed replacement. We are starting with the fence on the north side of Vestal Street along the front of the Maria Mitchell Vestal Street Observatory (MMO). This fence is being replaced with part of a grant from the Community Preservation Act. The grant was for the exterior conservation work and landscape issues related to the MMO. The current fence is approximately thirty-five years old so it did rather well. It had replaced a very old fence – one I wish we had kept! But it had been hit many times by cars and had so much paint on it, they decided to replace it. We have small part of that fence still and we will be reproducing it for all the fences we are replacing here on Vestal. The fence is not much different than a normal picket here on island – it’s a hair shorter but it also has a sort of rolled top – not this cut style. I am excited to have this fence back! The new fences are being built by Michael Gault – owner of Gault Woodworking and a Nantucket Preservation Trust Traditional Building Methods award winner. His work is incredible – and lucky for us – he loves building fences!  So keep an eye out – work has begun already. The south side where the MMA Research Center and Hinchman House are located will be done in the fall in the same style. JNLF
