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

I have posted this during Women’s History Month before but because it is March and again Women’s History Month, I think it’s worth repeating. It’s clever and helps to tell an important story in women’s history while giving it a bit of a 21 st century twist. It comes via the National Women’s History Project. JNLF

NANTUCKET, MA—The Maria Mitchell Association (MMA) invites the community to take part in an important conversation on owl preservation. The MMA will host a free virtual panel bringing together specialists in wildlife conservation to discuss the challenges these remarkable birds face today on Nantucket and beyond. This free presentation will take place Wednesday, March 18 from 6 – 7pm on Zoom. Owls are an essential part of Nantucket’s delicate island ecosystem. As natural predators, they help keep rodent populations in balance and serve as important indicators of environmental health. In recent years, however, growing threats—including the spread of Avian Influenza and the widespread use of rodenticides— have raised serious concerns for local owl populations and the broader bird community. This timely discussion will explore how these issues are affecting owls across the region and what they may mean for Nantucket’s wildlife and landscape. Panelists will share current research, discuss conservation efforts, and offer practical ways the community can help protect these iconic nocturnal hunters. By bringing together scientists, conservationists, and community members, the event aims to foster awareness and collaboration around protecting Nantucket’s natural heritage. Residents, nature enthusiasts, and anyone interested in the island’s wildlife are encouraged to join the conversation. The discussion will feature acclaimed naturalist and author, Scott Weidensaul, a Pulitzer Prize finalist for his book, Living on the Wind. He is also the author of A World on the Wing. A contributing editor to National Audubon and a longtime columnist for Bird Watcher's Digest, Weidensaul is a Fellow of the American Ornithological Society and co-founder of Project SNOWstorm, which tracks snowy owl movements through satellite telemetry. Joining Weidensaul will be Susan Baker of the Chicago Ornithological Society and the Chicago Bird Alliance Rodenticide Committee; Meaghan Q. Sinclair, a Mass Audubon Certified Field Naturalist, wildlife photographer, co-founder of Save Concord Wildlife, and member of the Mass Audubon Governance Council; Heather Packard, Community Organizer with Mass Audubon’s Policy & Advocacy team and manager of Climate and Nature Champions; Gwen Shipley, a Council Co-Leader and Climate and Nature Champion with Mass Audubon; and Ginger Andrews, the MMA’s Field Ornithologist. Together, these distinguished experts bring deep scientific expertise, conservation leadership, and extensive field experience to a timely and engaging discussion. This event will be held via Zoom. Pre-registration is required. To register for the free, virtual event, use the registration link: https://us06web.zoom.us/webinar/register/WN_9EGqyJ3XT06N8-GU14iuog#/registration The Science Speaker Series is generously sponsored by the Maria Mitchell Association’s lead sponsor, Bank of America.

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. ###

It’s sort of funny what Mother Nature does. Granted, in this case, she had a little help by shovel or plow. But as I made my way up Vestal Street a week ago or so, after the first round of eight inches of snow or so, I noticed this ice shape on the front stoop of the Mitchell House. To me, it looks like a whale with its tail up in the air! I think it’s sort of appropriate for this front stoop so I decided to share! JNLF
