Nantucket Maria Mitchell Association Astronomers Travelled to Largest Ground-based Optical Telescope in the World for Research

January 30, 2024

NANTUCKET, MA — Last December, the MMA astronomers travelled to the site of the largest ground-based optical telescopes in the world, the Keck Observatory, located on the Big Island of Hawai’i.  The MMA’s National Science Foundation (NSF) astronomy post-baccalaureate research fellows, Emmy Wisz and August Muller, travelled to Keck to obtain observations of distant galaxies for their research projects focused on unraveling the mysteries of the universe. 

 

Located at nearly 14,000 feet elevation near the summit of Mauna Kea, Keck is accessed remotely by astronomers around the world who operate the telescopes’ scientific instruments and collect astronomical data. The 10-meter telescopes are essential tools for many research projects, so groups must participate in a competitive process of proposal submission to secure observing time.  Because of the effects of potentially severe altitude sickness, astronomers observe from the base of the mountain  ̶  at Keck Headquarters in Waimea. Over the course of each night, astronomers operate the instruments from the remote operations room at Keck Headquarters, while being in continual contact with the telescope operators who are located on the summit.   

 

Wisz and Muller joined in on observations as part of two international collaborations that were co-founded by the MMA’s Director of Astronomy, Dr. Regina Jorgenson, and supported by grants from the NSF).  The first collaboration, called the Fast and Fortunate for FRB Follow-up, or F4 Collaboration, is using the Keck telescopes in an effort to probe the cosmic web, to understand what makes up the space between galaxies, and to identify the progenitors of the still mysterious fast radio bursts – extremely energetic and brief flashes of radio radiation.  The second collaboration, called the Multi-wavelength Analysis of Neutral Gas Observed in Emission and Spectroscopy, or MANGOES Collaboration, is utilizing the cutting-edge astronomical technology on the largest telescopes in the world to detect and study the elusive “baby galaxies” – those forming just a few billion years after the Big Bang.   

 

While at Keck, Wisz and Muller met several of the collaborations’ members, including Prof. J. Xavier Prochaska of the University of California, Santa Cruz and Dr. Marc Rafelski of the Space Telescope Science Institute, and learned first-hand how to conduct observations with Keck’s cutting-edge instruments.   

 

When asked to describe their experience participating in the observing run, and what it was like to travel to the Keck telescopes, post-baccalaureate research fellow Emmy Wisz stated, “I feel incredibly lucky to have been able to be so intimately involved in this process for four nights, especially as a junior astronomer. I am especially lucky that three of the four nights I was involved in were clear with no major weather issues! There is incredible value in seeing how the telescopes and instruments work in real-time and watching the data be read out after each exposure.” 

 

August Muller added, “Keck is an optical telescope, which means that most of the light measured is that which we can see with our eyes. While some other types of telescopes (especially those observing radio) can operate all day long, optical telescopes really do need to be used only at night. Nothing has made me feel more like an astronomer than the experience of working all night and sleeping once the sun rises in the morning.” 


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 female 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.

Maria Mitchell In Her Own Words

By Jascin N. Leonardo Finger • August 17, 2026
August 19 {1857}. There are four great men whose haunts I mean to seek, and on whose footsteps I mean to stand: Newton, Shakespeare, Milton, and Johnson. To-day I told the driver to take me to St. Martin’s, where the guide-book says that Newton lived. He put me down at the Newton Hotel, but I looked in vain to its top to see anything like an observatory. I went into a wine-shop near, and asked a girl, who was pouring out a dram, in which house Newton lived. She pointed, not to the hotel, but to the house next to a church, and said, “that’s it – don’t you see a place on the top? That’s where he used to study nights.” It is a little, oblong-shaped observatory, built apparently of wood, and blackened by age . . . .” Blackened no doubt by the wood ash and soot found in the air throughout over-crowded nineteenth century London. We always think about London being very foggy in the nineteenth century but frankly a lot of it was wood and coal ash as the nineteenth century grew older, particularly as factories developed and belched all of that into the air – think Sherlock Holmes in the 1880s. But Maria Mitchell, while starting in Europe as a young woman’s chaperone, also knew that this tour of Europe was a great learning experience – the equivalent of a college education she could not have. Doors were thrown open to her around Europe – in particular at all of the observatories that dotted the continent. She was not just well-known – she was famous. JNLF

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
