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

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • July 7, 2025
July 31, 1883. I had two or three rich days! On Friday last I went to Holderness, N.H.. to the Asquam House; I had been asked by Mrs. T to join her party. There was at this house Mr. Whittier, Mr., and Mrs. Cartland, Professor and Mrs. Johnson, of Yale . . . The house seemed full of fine, cultivate people. We stayed two days and a half. And first of the scenery. The road up to the house is a steep hill, and at the foot of the hill it winds and turns around two lakes. The panorama is complete one hundred and eighty degrees. Beyond the lakes lie the mountains.  The Asquam House sat atop Shepard Hill and was built in 1881. A hotel, it has space for fifty guests, it was located near Squam Lake and became part of a summer enclave that developed there in the later part of the nineteenth century. Today, the area is a National Historic Landmark, but sadly, the hotel was demolished in 1948. Maria would have been familiar with these people seen here – and others I did not include – but particularly John Greenleaf Whittier who was something of a family friend. He was close to one of her younger brothers, William Forester. JNLF

The Birth of the Maria Mitchell Observatory: Celebrating Over 100 Years of Discovery

By Jascin N. Leonardo Finger • June 30, 2025
As we are now complete with the conservation of the historic Maria Mitchell Vestal Street Observatory (MMO), I thought it would be good to post a series of blogs concerning it history and activities, as well as some of the amazing people who have made it what it is over the last 100 plus years. Therefore, over the next few weeks, the focus will be on the MMO. And it is now open for tours – Monday through Saturday 11-1PM. Founded in 1902, the Nantucket Maria Mitchell Association (MMA) had its beginnings in the Mitchell House where Maria Mitchell was born. Over the first few years, the preservation of the Mitchell House, family artifacts, and the collection and display of Nantucket’s native flora and fauna, as well as a small library, were the key components of the MMA. Special “Moon Evenings” were held on the lawn and people observed Nantucket’s night skies using several small telescopes, including William and Maria Mitchell’s two-and-three-quarter-inch Dollond telescope. The popular evenings led to the inevitable – a desire and need to expand based on the demands of the visitors to, and members of, the MMA. In 1906, Lydia Hinchman, a founder of the MMA and a family member, purchased the house and lot adjacent to the Mitchell House. The house – once the home of William Mitchell’s father and mother – was taken down. The MMA began a dialogue with the Harvard College Observatory and its director, Edward Pickering, Ph.D. The connection to Harvard was to become essential to the success of the beginning years of the Maria Mitchell Observatory and continued a legacy of friendship and work – Maria Mitchell and her father worked with the Bonds who once ran the observatory at Harvard and the families were close friends. Besides his assistance, Pickering asked a member of his staff, Annie Jump Cannon, to assist the MMA. This “provided an indispensable collaboration for Nantucket astronomy,” with Cannon spending two weeks on the island in 1906 and 1907 lecturing and teaching. While back at Harvard, she continued to teach the students on Nantucket by mail. Cannon would go on to be recognized as the leading woman astronomer of her generation and as the founder of the MMA’s Astronomy Department. JNLF
