In newly published research, CU Boulder scientists study a rocky exoplanet outside our solar system, learning more about whether and how planets maintain atmospheres

In June 2019, Harvard astrophysicists discovered a rocky exoplanet 22 light years from Earth. Analyzing data from the Transiting Exoplanets Survey Satellite (TESS), they and other scientists around the world learned key details about the rocky exoplanet named LTT 1445 A b: It is almost 1.3 times the radius of Earth and 2.7 times Earth’s mass and orbits its M-dwarf star every 5.4 days.

What they couldn’t ascertain from those data, however, was whether LTT 1445 A b has an atmosphere, “and that’s a big general question even in our own solar system: What sets how much atmosphere a planet has?” says Zach Berta-Thompson, a ��Ƶ assistant professor of astrophysical and planetary sciences. “Atmospheres matter for life, so before we go searching for life on other planets, we need to understand a very basic question—why does a planet have atmosphere or not have atmosphere?”

Pat Wachiraphan (left), a PhD student in the CU Boulder Department of Astrophysical and Planetary Sciences, and Zach Berta-Thompson (right), an assistant professor in the department, collaborated with colleagues around the country to study JWST data about rocky exoplanet LTT 1445 A b.

Now, after detailed analysis of data from the James Webb Space Telescope (JWST), a lot more is known—and was recently published—about LTT 1445 A b, whether it has an atmosphere and what its atmosphere might be if it has one. CU Boulder researchers partnered with astrophysicists around the country to build on previous research that ruled out a light hydrogen/helium-dominated atmosphere but could not distinguish between a cloudy atmosphere, an atmosphere composed of heavier molecules like carbon dioxide or a bare rock.

The paper’s first author, Pat Wachiraphan, a PhD student studying astrophysical and planetary sciences, Berta-Thompson and their colleagues analyzed three eclipses of LTT 1445 A b from the JWST, watching the planet disappear behind its star and measuring how much infrared light the planet emits. From this, they were able to rule out the presence of a thick carbon dioxide atmosphere like the one on Venus, which has about 100 times more atmosphere than Earth. This highlights an important aspect of science: Sometimes just as much is learned from understanding what something isn’t as from defining what it is.

“What I think should be the next step, naturally, is to ask whether we might detect an Earth-like atmosphere?” Wachiraphan says.

Not like Venus

LTT 1445 A b is one of the closest-to-Earth rocky exoplanets transiting a small star, Wachiraphan notes, and thus one of the easiest to target when studying whether and how it and similar rocky exoplanets hold atmospheres.

The JWST is more sensitive to atmospheres of transiting exoplanets around smaller stars, and LTT 1445 A b transits one of the smallest known type stars—about 20 to 30% the radius of Earth’s sun.

In November 2020, Berta-Thompson and several colleagues submitted a proposal to the Space Telescope Science Institute, the international consortium that decides where JWST is pointed and for how long, “before the telescope had even launched,” he says. “Scientists from all over the world send in anonymized proposals where we make our case for why (JWST) should spend hours looking at this particular patch of the sky and what we would be able to learn from that.

“A panel reads through the proposals, ranks them, from which a lucky 5% to 10% will be selected as the best possible scientific use of the telescope. It is such a precious resource that we care really deeply that the choices about who gets to use the telescope are made fairly; every minute of its time is accounted for.”

Studying data from three eclipses sent back by JWST, Wachiraphan, Berta-Thompson and their colleagues were able to chart thermal emission consistent with instant reradiation of incoming stellar energy from a hot planet dayside. “This bright dayside emission is consistent with emission from a dark rocky surface, and it disfavors a thick, 100-bar, Venus-like CO2 atmosphere,” the researchers noted.

“So, you can imagine that if you have a planet that is just a rock, with no atmosphere, it would be hot on day side and cold on the night side, but if it has atmosphere, then the atmosphere could redistribute heat from day to night,” Wachiraphan says.

In the case of LTT 1445 A b, “we were basically putting an infrared thermometer up to the planet’s forehead and learned its average temperature is around 500 Kelvin,” Berta-Thompson says. “The whole planet is like the inside of a hot oven, basically.

Based on the data sent back by JWST, there could be several ways to detect atmosphere on LTT 1445 A b. “We came up with an observation with this planet passing behind its star. When the planet is behind its star, we’d just get light from the star itself, but before and after the eclipse we’d get a little contribution from the planet itself, too.” Wachiraphan explains. “But you can also detect an atmosphere when a planet passes in front of its star. “The starlight coming out could pass through the atmosphere of the planet and get absorbed, and we could observe that absorption.”

More observations are currently planned for LTT 1445 A b, led by other scientists and using this complementary method of observation, Berta-Thompson says—of collecting data as the planet transits in front of its star. “There’s a lot more we can learn using different wavelengths of light and different methods that allow us to more sensitively probe these thinner atmospheres.”

Like the inside of a hot oven

One of the most fascinating questions for researchers studying exoplanets, Berta-Thopson says, is “what does it take for a planet to retain or maintain atmosphere? Learning more about that is an important step in the process toward finding a planet maybe like this one—that has a surface, has an atmosphere, is a little farther away from its star, where you can imagine it has liquid water at the surface. Then you’re asking, ‘Is this a place where life could potentially thrive? Is there a place where life is thriving?”

These questions are so interesting, in fact, that they’ve prompted the formation of the Rocky Worlds Program, with which Wachiraphan and Berta-Thompson will work closely, to support international collaboration on the next phases of exploration of rocky exoplanets using satellite data.

“Using this really magnificent telescope that is the collective effort of thousands of people over decades, let alone the broader community that found this planet, is the kind of thing that is under threat right now,” Berta-Thompson says. “All of this science and this discovery requires a really long, big, sustained investment in telescopes, in scientists, in education.”

India and Pakistan once again step back from the brink

India and Pakistan once again step back from the brink Rachel Sauer Fri, 05/16/2025 - 10:44

CU Boulder historian Lucy Chester notes that the recent tensions between the two nations, incited by the April 22 terrorist attack in Kashmir, are the latest in an ongoing cycle

When a gunman opened fire April 22 on domestic tourists in Pahalgam, a scenic Himalayan hill station in Indian-administered Kashmir, killing 26 people, the attack ignited days of deadly drone attacks, airstrikes and shelling between India and Pakistan that escalated to a perilous brink last weekend.

A U.S.-brokered ceasefire Saturday evening diffused the mounting violence between the two nuclear-armed nations that increasingly seemed on a trajectory toward war. It was the latest in a string of escalations spanning many decades between India and Pakistan, which invariably led to the question: Why does this keep happening?

CU Boulder historian Lucy Chester notes that the recent conflict between India and Pakistan is part of a broader history that includes not only religion, but water, maps and territorial integrity.

Lucy Chester, an associate professor in the ��Ƶ Department of History and the International Affairs Program, has studied the region and relations between the two nations for many years; her first book, Borders and Conflict in South Asia, explores the drawing of the boundary between India and Pakistan in 1947.

Despite President Donald Trump’s assertion that the origins of the conflict date back a thousand years, “that’s not the case,” Chester says. “I would say it’s mainly about Kashmir, with some additional issues at play this time around that changed the dynamics a bit.”

When more than a century of British colonial rule of India ended in August 1947, the Indian subcontinent was divided into Hindu-majority India and Muslim-majority Pakistan—a bloody, devastating event known as Partition. An estimated 15 million people were displaced and an estimated 1 to 2 million died as a result of violence, hunger, suicide or disease.

The first Indo-Pakistani war ignited two months after Partition, in October 1947, over the newly formed Pakistan’s fear that the Hindu maharaja of the princely state of Kashmir and Jammu would align with India. The Indo-Pakistani wars of 1965 and 1971 and the the Kargil War of 1999 followed, as well as other conflicts, standoffs and skirmishes.

Chester addressed these and other issues in a recent conversation with Colorado Arts and Sciences Magazine.

Question: These decades of conflict are often framed as Hindu-Muslim conflict; is that not the case?

Chester: There’s an older dynamic of Hindu-Muslim tension that definitely plays a role in this, but a significant aspect of the conflict over Kashmir is a conflict over water, which is really important. It has to do specifically with Kashmir’s geopolitical position and how a lot of the water that is important to India, that flows through India into Pakistan, originates in Kashmir.

It was a lot about popular pressure this time—Hindu nationalist pressure—on (Indian Prime Minister Narendra) Modi, which is a dynamic that he has very much contributed to. So, in that sense, it could be framed as Hindu-Muslim tension.

But it’s also about territorial integrity—that’s a phrase that kept coming up—and it’s a very loaded phrase that does go back to 1947 and the kinds of nations that India and Pakistan were conceived of in the 1940s and the kinds of national concerns they’ve developed in the years since.

Question: What role did Hindu nationalism, which has been very much in the news since Modi’s re-election last year, play in this recent conflict?

Chester: Hindu nationalism has been important in South Asia since the late 19th century, certainly, and it’s become more important since the 1930s. It’s one strand of the larger Indian nationalist movement—Indian nationalism was behind the assassination of Mahatma Gandhi in 1948. So, it’s always been there, but Modi, of course, has really ramped it up. For a while he distanced himself from the BJP (the Bharatiya Janata Party political party associated with Hindu nationalism), but he’s since made it very clear that he is very much in line with Hindu nationalist ideals and played on those symbols and those dynamics centered to what Hindu nationalist voters wanted.

This whole idea of Hinduness gets back to the various ways both India and Pakistan are conceived of as nations. Hindutva (a political ideology justifying a Hindu hegemony in India) conceives India as a fundamentally Hindu nation, and that idea has gotten so much more reinforcement from Modi and the national government over last 10 years. So, part of what happened with this awful terrorist massacre two weeks ago is that it created a lot of pressure on Modi to respond in a way that previous Indian administrations haven’t felt they had to respond.

Question: In the recent conflict, India accused Pakistan of perpetrating the attack, which Pakistan denied, and framed the response as a defense of ‘Mother India.’ What does that mean?

Chester: Sumathi Ramaswamy explained it best in her book (The Goddess and the Nation: Mapping Mother India), where she talks about Mother India as this cartographed divine female figure who’s very much identified with the cartographic body of the nation. So, any attack on the territorial integrity (of India) is an attack on this woman, this mother figure.

The (recent) Indian Operation was called Operation Sindoor—sindoor is the red coloring that married Hindu woman put in the part of their hair—a call-out to this idea of Mother India and a call to the nation’s sons to be willing to die for her or to kill for her in this case.

In 1947, with the Partition of British India into India and Pakistan, the conception for many in India was a really tragic carving up of the body of the nation, and for a number of Hindu nationalists, that was a specifically female body. For a lot of people in India to this day, the 1947 Partition is this massive failure and an amputation of key elements of the national body. On the other side in Pakistan, for many it’s this great narrative of victory, but on the Indian side there’s this recurring existential fear that further parts of the country could be carved off this way. I think a big part of why conflict keeps happening is that both sides feel very strongly about defending the national territory because it was torn apart in such a violent way, and I think that fear is just most vividly present in Kashmir.

Question: How does the history of Kashmir in terms of British rule and Partition come into play?

Chester: In terms of British India, there were areas that were directly ruled and areas that were indirectly ruled. The indirectly ruled areas were princely ruled, and this is important because Kashmir was a princely state with a Hindu maharaja and a majority-Muslim population. With princely states, in theory they could decide for themselves whether to accede to India or Pakistan, and the maharaja of Kashmir, most would say he was angling for some kind of autonomy or independence and delayed the decision on whether to accede to India or Pakistan.

In October of 1947, militia groups—almost certainly supported by Pakistan—invaded Kashmir and the maharaja appealed to India for help. India airlifted troops in, because there was no all-weather road efficient for deploying troops, which gives you a sense for both how remote Kashmir was and parts of it still are, and also that there weren’t a lot of infrastructure connections.

So, the first Indo-Pakistan war was in 1947 to 1948, then a second war in 1965 and a third in 1971. This reinforces that fear of the country fragmenting and losing parts of the national body, because it was after the 1971 war that Bangladesh became independent (from Pakistan).

In 1949, India and Pakistan established a Ceasefire Line that became the Line of Control in 1972 with the Simla Agreement. The Line of Control is significant because it’s treated as an international boundary—not de jure (existing by law or officially recognized), but de facto. In 1972, officials came up with a textual description for the Line of Control and they define it up to NJ9842, which is the northernmost point on the map where it ends. The text of treaty says something like, “Proceed thence north to the glaciers.” This territory is so remote, so geopolitically useless, that no one at the time thought spending time to define where boundary line ran was important.

In the mid-1980s, both India and Pakistan sent troops to the Siachen Glacier, creating one of the highest more-or-less permanent military bases at about 22,000 feet. (Photo: Wikimedia Commons)

So, north of NJ9842 is this really undefined area—you’ve got Pakistan-controlled territory, India-controlled territory, China is right there, the Karakoram Pass is right there. What happened in the late 1970s, and possibly earlier even into the late 1960s, was Pakistan began issuing permits to international climbing expeditions, and in the early 1980s Indian troops discovered evidence of these international climbing expeditions. India realized that Pakistan had been exercising a certain form of administrative control over this undefined territory, and that’s what triggered the mid-1980s sending of troops from India and Pakistan to the Siachen Glacier. It includes what I think is the highest more-or-less permanent military base at something like 22,000 feet.

As a map geek, I find it really interesting that maps have contributed in pretty direct ways to these conflicts. One of the really tragic elements is that we know that on the Indian side, 97% of conflict casualties in that area are due to terrain and weather, and we can assume similar numbers on the Pakistani side. You’ve got these two countries fighting this battle, but they’re also fighting Mother Nature. In fact, the 1999 Kargil War happened because Pakistan tried to move some of its troops to a higher altitude where they could overlook an Indian road that supplied these high-altitude posts.

Question: What role did water play in the recent conflict?

Chester: All of the water that feeds the rivers that run downstream into western India and Pakistan originates in that region, which gives it real geopolitical value. One of the things that had me particularly concerned this time was India suspended the Indus Waters Treaty from 1960, which was a really landmark agreement governing the sharing of these waters. Some of these rivers flow through India before they get to Pakistan, and at this point India doesn’t have the infrastructure to turn off the water. But Pakistan has said if India starts building that infrastructure, they will consider it an act of war.

Question: Is there anything that makes you feel even slightly hopeful amid these ongoing tensions?

Chester: Over the last two weeks, both sides have been very carefully walking this fine line between being very visibly seen to acknowledge popular pressure on them to stand up strongly to their adversary, but also making very carefully planned choices that as far as possible avoided uncontrollable escalation. Everyone is keenly aware these are both nuclear-armed powers. I was very concerned that it escalated as much as it did on both sides, particularly in the use of airstrikes, but I think both sides were doing their best to leave themselves and their adversaries an off-ramp.

Part of the significance of (the Kargil War in) 1999 was both sides had just come out of the nuclear closet, so everyone was watching that conflict very closely, but both sides were able to walk back from edge. That gives us a lot of reason to hope and to believe that there are very professional people on both sides—in addition to people who are whipping up popular frenzy—who have a good sense for what the limits are, what signals they can send, and who are saying to the population, “We listen to you, we respect your grievances,” but they also know where the edge is and aren’t crossing it.

An apple a day? It’s the Boulder way

Newly planted apple orchard on CU Boulder campus is a nexus of university and community partnerships and will be a living classroom for students and educators

For now, they are twiggy little things, all spindly adolescent limbs that nevertheless hint at future harvests. Saturday morning, one even wore a scattering of creamy white blossoms—flowers that, in years to come, once roots have gained hold and branches have stretched up and out, will grow into apples.

Is there anything more hopeful than planting a tree? Yes, planting a whole orchard of them.

On Saturday, years of planning, research and partnership-building bore fruit on an L-shaped plot in front of the ��Ƶ 30th Street greenhouse, where more than two-dozen volunteers planted 30 apple trees in what had previously been a scrubby patch of turf.

Funded by a $90,000 Sustainable CU grant, the apple orchard will not only be a classroom and a living lab, but a nexus for community, a carbon sink and a vibrant example that sustainability can be delicious.

“It’s so exciting to see this happening,” says Amy Dunbar-Wallis, who this semester completed her PhD in the Department of Ecology and Evolutionary Biology and collaborated with CU Boulder faculty and students and community partners to bring the idea of the first orchard on CU Boulder campus to fruition.

“It represents how so many people on campus, so many people in the community, have come together to plant this orchard that will be a place to learn and a place to preserve a really neat part of Boulder’s history.”

In search of old apple trees

The new apple orchard grew from the Boulder Apple Tree Project, an initiative that began almost 15 years ago with a simple observation: There seemed to be a lot of old apple trees in Boulder.

Katharine Suding, a professor of distinction in the Department of Ecology and Evolutionary Biology, had recently moved to the area, “and I was really surprised to see so many old apple trees everywhere,” she recalled during the 2022 Apple Symposium. “I realized I had no idea about the histories and particularly the history of apples, so looking into it a little more, it was clear there are trees here that are remnants of past histories starting in the turn of (20th) century.

Amy Dunbar-Wallis (left) and Tiffany Willis (right, EBio'22) consult a chart designating where each tree would be planted in the new apple orchard in front of the 30th Street greenhouse Saturday morning. Willis, who lives in Boulder, took EBIO 1250 online during Covid lockdowns and was a lab assistant for the class in 2021.

“There are apple trees in Colorado and in Boulder that are remnants from old orchards that still exist. There are also remnants of trees that were planted when people came and built ranches or had farms here, and often they were bringing along apple trees from where they came from, whether it was Germany, whether it was the Midwest, whether it was Scandinavia.”

In fall 2017, the Boulder Apple Tree Project (BATP) sprouted, combining historical sleuthing with cutting-edge genetic testing and grafting to not only locate and catalog Boulder’s historic apple trees, but also to revive its legacy of apple growing. In the ongoing project, researchers gather data on the age and health of the trees, as well as the type and flavor of the apples, and the genetic diversity that the trees offer to future populations.

Suding and BATP co-principal investigator Lisa Corwin, an associate professor of ecology and evolutionary biology, have worked with undergraduate and graduate students not only to gather data, but also to develop the EBIO 1250 course, during which students conduct research on Boulder’s apple trees; curricula and materials in partnership with the CU Museum of Natural History; a database and app in collaboration with computer science students; an interactive map of apple trees that have been tagged and studied; and the A Power of Place Learning Experience and Research Network (APPLE R Net), a multi-institution research network directed by Corwin that introduces students to field research by involving them in a project examining apple trees across the Rocky Mountain region.

BATP also is part of the Historic Fruit Tree Working Group, which connects Colorado researchers with other apple-exploring groups and researchers across North America.

Mia Williams (left) waters a newly planted apple tree Saturday morning. Williams, who will graduate this summer, is double majoring in ecology and evolutionary biology and environmental studies.

“This project has grown so much since our initial community engaged Apple Blitz in 2018,” says Dunbar-Wallis. “We've tagged over 1,000 trees and created a database, taught multiple course-based undergraduate research experiences at CU and at colleges across Colorado and northern New Mexico, started a data-collection app and interactive map in collaboration with CU computer science capstone students and installed a demonstration orchard in collaboration with Boulder Open Space and Mountain Parks.”

The demonstration orchard, planted two years ago, functions as a teaching and research laboratory to explore how biodiversity affects the functioning of apple orchards and their services to human well-being, including efficient water use, pollinator habitat and structural complexity supporting natural pest control.

A part of the narrative

The idea for the 30th Street orchard was revived by a group of six undergraduate and two graduate students almost two years ago, who proposed resubmitting a grant application that hadn’t been accepted in 2019.

“We’re a group who really love what we do and love apple trees and working with the soil,” says Katie Mikell, an ecology and evolutionary biology student who is graduating today and who was a member of the team that crafted and submitted the grant proposal.

“Before, (the orchard plot) was a lawn full of monoculture turf grass, so part of our argument was that if we put in an apple orchard, it would create a carbon sink (a system that absorbs more carbon than it releases), it would save the school money and anyone walking by could pick an apple. Plus, once the trees are producing, we can donate apples to the food pantry. Everyone can benefit from an apple orchard.”

Deidre Jaeger (right, PhDEBio'22) and her sons Sage, 4 (left), and Cedar, 1 (center), plant apple trees at the 30th Street orchard Saturday morning. Jaeger was a postdoctoral researcher in the Department of Ecology and Evolutionary Biology and an advisor for the Center for Sustainable Landscapes and Communities and is a researcher with the Boulder Apple Tree Project.

Students prepared the 30th Street site during fall semester, working with departments and organizations across the university, as well as many community partners. The trees planted Saturday are about three years old and were obtained from Widespread Malus and Benevolence Orchard in Boulder.

“Our students are at the core of the university, and their passion and ingenuity are critical to our values around infusing sustainability throughout CU Boulder. This orchard exemplifies that pursuit in so many ways,” says Vice Chancellor for Sustainability Andrew Mayock.

“It is not only helping to protect biodiversity in our community. It will help feed those in need on our campus and create a living-learning laboratory space where sustainability leaders of the future will learn and develop strategies for urban agriculture planning.”

Fifteen varieties of apples are represented in the orchard, including locally grown historic cultivars like Wolf River and Colorado Orange. A beloved apple tree on the Bobolink Trail is even represented in a newly planted graft.

“There’s so much learning that can happen in an orchard,” says Manuela Mejia, an ecology and evolutionary biology PhD student who will conduct her doctoral research, which will include studying insect diversity, at the orchard. “So many facets of science are represented here.”

In addition to trees, the orchard will include an understory of native, drought-tolerant grasses and pollinator-friendly wildflowers, notes Mia Williams, who is majoring in environmental studies and ecology and evolutionary biology and will graduate this summer.

“It’s really exciting that this orchard will become a part of the story of agriculture in this area,” Dunbar-Wallis says. “We’ve tagged more than 1,000 trees (through BATP) and some of them are a hundred years old, so you think about everything they’ve seen and been through, the history that they hold, their stories, and now these trees—which are little now and probably won’t produce fruit for two or three years—are part of that narrative.”

Newly opened exhibit at the University of Colorado Museum celebrates ceramic artist’s donation and the legacy of her family and community

A new piece of Acoma Pueblo pottery begins, in a way, with all the pottery that came before it.

Artisans finely grind shards of old pottery and mix it into clay gathered from Acoma Pueblo land, hand-forming the light yet strong vessels for which they are renowned. There are no precise measurements, no written recipes, for the clay or slip or mineral paints that come together in Acoma Pueblo pottery; “you just know when it’s right,” says artist Dolores Lewis Garcia.

Noted Acoma Pueblo ceramics artist Carmel Lewis Haskaya, a proud CU Boulder alumnus, ensured that her love for her community and its traditions would unite with her love for CU Boulder by donating one of her pieces to the University of Colorado Museum.

Lewis Garcia learned the art from her mother, Lucy M. Lewis, the famed New Mexico ceramics artist known for reviving traditional pottery techniques whose work is displayed in the Smithsonian National Museum of the American Indian. Most of Lewis’ nine children learned by watching her and also became ceramic artists, including her youngest, Carmel Lewis Haskaya.

Lewis Haskaya was not only a respected ceramic artist, but a proud ��Ƶ alumnus. Before her death in 2019, she ensured that her love for her community and its traditions would unite with her love for CU Boulder by donating one of her pieces to the University of Colorado Museum.

The vibrant cylindrical pot is a centerpiece of the new exhibit “A Family Tradition: Acoma pottery, CU and the Lewis family,” which opened with a reception and ribbon cutting Tuesday evening.

“We are delighted to highlight and honor the important artworks that this family has shared with us,” says Nancy J. Stevens, CU Boulder professor of anthropology and director of the Museum Institute. “It represents a pivotal point for connecting communities and growing meaningful collaborations into the future.”

The exhibit features pieces by Lucy Lewis and many of her children, including Forever Buff Carmel Lewis Haskaya.

“(Lewis Haskaya’s cylinder jar) is not just an object or a gift,” explains William Taylor, a CU Boulder assistant professor of anthropology and CU Museum curator of archaeology who partnered with the Lewis family to create the exhibit.

“For many folks, creating pottery is a way to impart something of yourself in a permanent and lasting way. Having this pottery at CU means that a part of Carmel and her family will always be here in Boulder.”

Learn by watching

Lewis Haskaya belonged to an artistic lineage that can be traced in centuries. For hundreds of years, Acoma Pueblo artists have gone to certain spots on their land to collect the clay, white slip, wild spinach and oxides that are the raw materials for their pottery.

“Being an Acoma potter, there’s a lot of work that goes into it,” Lewis Garcia says.

“Everything is gathered from the land and hand-processed,” adds Claudia Mitchell, also a famed Acoma Pueblo artist and Lewis’ granddaughter. “It teaches you to take your time and be present; you’re putting yourself into the work.”

As a child, Lewis Haskaya learned these traditions and techniques watching her mother. When she came to CU Boulder through the American Indian Educational Opportunity Program and built a career with the Native American Rights Fund, she never forgot or outgrew her community, Mitchell says. Eventually, Lewis Haskaya returned to her community at Acoma, west of Albuquerque, New Mexico, and became an accomplished artist.

Lewis Haskaya was a student of history and art traditions from around the world and was known for creating cylinder vessels in the style of ones found at Chaco Canyon, Mesa Verde and other ancient sites, adding her own touch to traditional designs.

The cylindrical vessel made by noted Acoma Pueblo artist Carmel Lewis Haskaya, which she donated to the University of Colorado Museum before her death in 2019.

“She had the hardest time grinding mineral paints,” Lewis Garcia recalls with a laugh, adding that her sister eventually conquered the hurdle that many artisans using traditional techniques encounter.

Like her mother and siblings, and now her nieces and nephews, Lewis Haskaya walked Acoma land to specific spots for the gray and yellow clays, the minerals and the plants that are the foundation of traditional techniques. “To get the white slip, it’s not in an easy place,” Lewis Garcia says. “It’s underground and there’s a big boulder on it. You have to use it sparingly.”

Though it’s more common now to use kilns rather than dung fires, the process of thinning vessel walls, of burnishing with a stone, of applying the geometric patterns associated with Acoma Pueblo pottery hasn’t changed for centuries.

‘The ties that bind us together’

While pottery is revered as art, “in our traditional ways, it’s a utility, it’s an item that we use,” says Benny Shendo Jr., CU Boulder associate vice chancellor for Native American affairs and a member of the Jemez Pueblo Tribe. “And it plays a big role in our ceremonial life.”

Mitchell notes that traditional pottery helps not only those who make it, but those who use it to “ground ourselves to the place that we’re from; it’s that connection that we have to our land and to our people—not only just for personal use, but for community use. It gives us that tie to one another. We’re keeping those traditions alive not only through our dance and song but through our pottery.

“Those are the ties that bind us together, that make us a people. It’s important to keep those ties, to make sure that those things—the pottery making, the dancing, the singing—all of those are taught to our younger generations, because that helps them identify who they are and where they are. It helps give them a sense of place and sense of purpose.”

“It’s part of life,” says Diana Lim Garry (Anth'71), Lucy Lewis’ granddaughter who lives in Boulder and helped bring the exhibit to life, loaning pieces from her own collection. “Everywhere we go—you’re walking on a hike and you’re walking along the streambed, and you’re saying, ‘Would that make a good polishing stone?’ You go along, even (in) roadcuts there’s all these pretty colors of the minerals in the rocks: ‘Would that make good paint?’ It’s always on your mind that this is something that’s been done for a long time and will continue to be done thanks to my aunts and my cousins.”

Mitchell adds that a pottery vessel made in traditional ways allows the Acoma Pueblo people to say “I have my piece of the rock. That’s how we identify ourselves, by place and name, that’s our place in this world, and no matter where we go in this world, we can always go back to that one place, and that’s where we belong. For our people, that’s who we are, that’s where we’re from.”

"A Family Tradition: Acoma pottery, CU and the Lewis family” is open to the public during regular museum hours, which are 9 a.m. to 5 p.m. Tuesday through Friday and 10 a.m. to 4 p.m. Saturday and Sunday.

Pieces made by famed Acoma Pueblo artist Lucy M. Lewis are part of the new University of Colorado Museum exhibit "A Family Tradition: Acoma pottery, CU and the Lewis family."

Following in the footsteps of her grandmother, Lucy M. Lewis, Acoma Pueblo artist Claudia Mitchell made these pieces using traditional techniques and designs.

Scholars aim to build community for women in quantum Rachel Sauer Fri, 04/25/2025 - 13:46

Quantum Scholars Emily Jerris and Annalise Cabra started CU Women of Quantum to help women interested in careers in quantum to network and share experiences

First, the good news: Between 1970 and 2022, the percentage of U.S. women workers in STEM jobs grew from 7% to 26%.

The obvious and not-so-good news is that while women represent almost half the U.S. workforce, they hold only a quarter of STEM jobs. And the numbers get even more stark in quantum fields. A 2022 report from the London School of Economics and Political Science found that fewer than 2% of applicants for jobs in quantum fields are female.

However, in the 100 years since German physicist Werner Heisenberg submitted his paper “On quantum-theoretical reinterpretation of kinematic and mechanical relationships” to the journal Zeitschrift für Physik, a July 1925 event that is broadly credited with kick-starting the quantum revolution, the possibilities and potential of quantum science and engineering have grown enormously.

Recognizing that potential, a group of ��Ƶ scholars wants to help ensure that women participate equally and fully in quantum science and engineering.

CU Women of Quantum, founded last semester by Quantum Scholars Emily Jerris and Annalise Cabra, aims to be a community of support, connection, mentorship and networking for women interested in pursuing careers or research in quantum fields.

“Our primary focus,” Cabra explains, “is just to create a space where we can come together, share our experiences and create relationships that are lasting.”

100 years of quantum

Both Jerris and Cabra say that this is an exciting time to be in quantum science and engineering. Not only did the United Nations declare 2025 as the International Year of Quantum Science and Technology, and not only did Colorado Gov. Jared Polis last week announce the Blueprint for Advancing K–12 Quantum Information Technology, but research happening on the CU Boulder campus and in Colorado is swiftly expanding the boundaries of quantum technology.

However, they also add that as exciting as this time is, women in quantum fields still face some of the same roadblocks that women in STEM always have.

“I think if you asked most of the women in the club or just in a STEM major if they’ve had a moment where a peer or coworker has talked down to them or they felt not necessarily fully included in a project because they were the only woman in the group, I think most probably have,” Jerris says. “So, it’s nice to have a space to talk about that—how to navigate situations like that. A lot of us do research, too, and those types of situations are also really prevalent in the research space.”

Jerris and Cabra worked with Michael Ritzwoller, a physics professor of distinction and Quantum Scholars co-founder, and physics Professor Noah Finkelstein to create CU Women of Quantum, which is open to all students, as a place for not only female Quantum Scholars, but for women across campus who are interested in pursuing careers in quantum science, technology or engineering.

Annalise Cabra (left) works with Brooke Nelson (right), a career advisor for the College of Engineering and Applied Sciences, on her resume during a recent CU Women of Quantum meeting.

Supporting women in quantum

One of the group’s aims is creating networking and mentorship opportunities for members by asking professors and women working in quantum fields to speak at group meetings. This has included Alex Tingle, a CU Boulder physics alumna and senior technical project engineer at Quantinuum, who was named one of the Wonder Women of the Quantum Industry by the Quantum Daily.

CU Women of Quantum gatherings also focus on skill-building, including a recent meeting at which Brooke Nelson, a career advisor for the College of Engineering and Applied Sciences, gave a presentation on creating and honing a resume.

“One of our goals is to help (CU Women of Quantum members) narrow in on their interests and build connections,” Cabra says. “And then also having opportunities to see how women in their shoes were able to navigate and build careers in quantum. I think it’s important for a lot of women in the field, too, to go back and encourage other women who are just starting out or just getting interested in quantum.”

The members of CU Women of Quantum also get together for study sessions, “because even if we’re not taking the same classes, with other women you can feel more open and not like you’re the outlier in the group.”

Both Cabra, who is graduating next month, and Jerris, who is completing her third year, are interested in pursuing careers in a quantum field, bolstered by the support they’ve found in CU Women of Quantum.

“It’s so fascinating because it’s just so unintuitive,” Cabra says. “It makes your brain think in such crazy ways, from the ways particles behave to the ways stars don’t collapse or do collapse, to parallel universes, and it all goes back to quantum. I think it’s just so exciting to study.”

Jerris adds that often the common perception of quantum science and technology is that “it’s kind of magic or something we don’t totally understand, but we actually do have a pretty good understanding of quantum. We know what’s going on and can model it, and we’re maybe just one step behind with how we can actually manipulate things. So, it’s not magic; it’s something we do know a lot about and we’re learning more every day.”

In the archaeological record, size does matter

In the archaeological record, size does matter Rachel Sauer Mon, 04/14/2025 - 09:24

CU Boulder archaeologist Scott Ortman and colleagues around the world explore relationships between housing size and inequality in PNAS Special Feature

If the archaeological record has been correctly interpreted, stone alignments in Tanzania’s Olduvai Gorge are remnants of shelters built 1.7 million years ago by Homo habilis, an extinct species representing one of the earliest branches of humanity’s family tree.

Archaeological evidence that is unambiguously housing dates to more than 20,000 years ago—a time when large swaths of North America, Europe and Asia were covered in ice and humans had only recently begun living in settlements.

Between that time and the dawn of industrialization, the archaeological record is rich not only with evidence of settled life represented by housing, but also with evidence of inequality.

CU Boulder archaeologist Scott Ortman partnered with colleagues Amy Bogaard of the University of Oxford and Timothy Kohler of the University of Florida on a PNAS Special Feature focused on housing size in the archaeological record and inequality.

In a Special Feature published today in the Proceedings of the National Academy of Sciences (PNAS), scholars from around the world draw from a groundbreaking archaeological database that collects more than 55,000 housing floor area measurements from sites spanning the globe—data that support research demonstrating various correlations between housing size and inequality.

“Archaeologists have been interested in the study of inequality for a long time,” explains Scott Ortman, a ��Ƶ associate professor of anthropology who partnered with colleagues Amy Bogaard of the University of Oxford and Timothy Kohler of Washington State University to bring together the PNAS Special Feature. (Special Features in PNAS are curated collections of articles that delve into important topics.)

“For a long time, studies have focused on the emergence of inequality in the past, and while some of the papers in the special feature address those issues, others also consider the dynamics of inequality in more general terms.”

Kohler notes that "we use this information to identify the fundamental drivers of economic inequality using a different way of thinking about the archaeological record—more thinking about it as a compendium of human experience. It’s a new approach to doing archaeology.”

Patterns of inequality

Ortman, Bogaard and Kohler also are co-principal investigators on the Global Dynamics of Inequality (GINI) Project funded by the National Science Foundation and housed in the CU Boulder Center for Collaborative Synthesis in Archaeology in the Institute of Behavioral Science to create the database of housing floor area measurements from sites around the world.

Scholars then examined patterns of inequality shown in the data and studied them in the context of other measures of economic productivity, social stability and conflict to illuminate basic social consequences of inequality in human society, Ortman explains.

“What we did was we crowdsourced, in a sense,” Ortman says. “We put out a request for information from archaeologists working around the world, who knew about the archaeological record of housing in different parts of world and got them together to design a database to capture what was available from ancient houses in societies all over world.”

Undergraduate and graduate research assistants also helped create the database, which contains 55,000 housing units and counting from sites as renowned as Pompeii and Herculaneum, to sites across North and South America, Asia, Europe and Africa. “By no stretch of the imagination is it all of the data that archaeologists have ever collected, but we really did make an effort to sample the world and pull together most of the readily available information from excavations, from remote sensing, from LiDAR,” Ortman says.

The housing represented in the data spans non-industrial society from about 12,000 years ago to the recent past, generally ending with industrialization. The collected data then served as a foundation for 10 papers in the PNAS Special Feature, which focus on the archaeology of inequality as evidenced in housing.

Housing similarities

In their introduction to the Special Feature, Ortman, Kohler and Bogaard note that “economic inequality, especially as it relates to inclusive and sustainable social development, represents a primary global challenge of our time and a key research topic for archaeology.

In the PNAS Special Feature published Monday, researchers from around the world describe evidence of inequality found in archaeological data of housing size. (Cover image: Johnny Miller/Unequal Scenes)

“It is also deeply linked to two other significant challenges. The first is climate change. This threatens to widen economic gaps within and between nations, and some evidence from prehistory associates high levels of inequality with lack of resilience to climatic perturbations. The second is stability of governance. Clear and robust evidence from two dozen democracies over the last 25 years that links high economic inequality to political polarization, distrust of institutions and weakening democratic norms. Clearly, if maintenance of democratic systems is important to us, we must care about the degree of wealth inequality in society.”

Archaeological evidence demonstrates a long prehistory of inequality in income and wealth, Ortman and his colleagues note, and allows researchers to study the fundamental drivers of those inequalities. The research in the Special Feature takes advantage of the fact “that residences dating to the same chronological period, and from the same settlements or regions, will be subject to very similar climatic, environmental, technological and cultural constraints and opportunities.”

Several papers in the Special Feature address the relationship between economic growth and inequality, Ortman says. “They’re thinking about not just the typical size of houses in a society, but the rates of change in the sizes of houses from one time step to the next.

“One thing we’ve also done (with the database) is arrange houses from many parts of the world in regional chronological sequences—how the real estate sector of past societies changed over time.”

The papers in the Special Feature focus on topics including the effects of land use and war on housing disparities and the relationship between housing disparities and how long housing sites are occupied. A study that Ortman led and conducted with colleagues from around the world found that comparisons of archaeological and contemporary real estate data show that in preindustrial societies, variation in residential building area is proportional to income inequality and provides a conservative estimator for wealth inequality.

“Our research shows that high wealth inequality could become entrenched where ecological and political conditions permitted,” Bogaard says. “The emergence of high wealth inequality wasn’t an inevitable result of farming. It also wasn’t a simple function of either environmental or institutional conditions. It emerged where land became a scarce resource that could be monopolized. At the same time, our study reveals how some societies avoided the extremes of inequality through their governance practices.”

The researchers argue that “the archaeological record also shows that the most reliable way to promote equitable economic development is through policies and institutions that reduce the covariance of current household productivity with productivity growth.”

GINI Project data, as well as the analysis program developed for them, will be available open access via the Digital Archaeological Record.

Tales as old as time … yet we still love them

With yet another Snow White adaptation currently in theaters, CU Boulder scholar Suzanne Magnanini reflects on the enduring appeal of fairy tales

Once upon a time—this time, in fact, and many of the ones that came before it—there was a story that never grew dull in its telling.

It possibly leaped the porous cultural and national borders of narrative, carried by caravans or ships or ethernet cables and planted in the ready imaginations of successive generations of story lovers—those who tell them and those who hear them.

Maybe it’s the story of a young person who ventures into the unknown, where they encounter magic and beasts of all sizes and a resolution specific to the tale’s time and place. Maybe there really even are fairies involved.

Suzanne Magnanini, a CU Boulder associate professor of Italian and chair of the Department of French and Italian, notes that fairy tales' malleability helps them remain fresh and relevant over centuries of retellings.

And we never seem to tire of hearing about them.

The recent theatrical release of Disney’s live-action Snow White—one of countless retellings of the tale over more than 400 years—highlights the place of honor that fairy tales occupy in cultures around the world and in the hearts of people hearing them for the first time or the thousandth.

One of the reasons they remain fresh through countless years and iterations is their malleability, says Suzanne Magnanini, a ��Ƶ associate professor of Italian and chair of the Department of French and Italian. “The Italian author Italo Calvino, who also edited a seminal collection of Italian folktales, writes of fairy tales as being like a stone fruit, where you have that hard core center that is always the same—you’ll usually recognize a Sleeping Beauty story, for example—but the fruit can be radically different around that.”

Stories of time and place

As a researcher, Magnanini has published broadly on fairy tales, including her 2008 book Fairy-Tale Science: Monstrous Generation in the Fairy Tales of Straparola and Basile. She began studying fairy tales while working on her PhD, finding in them a fascinating dovetailing between her interests in monstrosity and otherness.

“As a scholar, I take what’s called a social-historical approach,” she explains. “I’m really interested in all those little details that link a tale to a very precise place in time where it was told, and I’ve written about the ways in which fairy tales are used to elaborate on and think about scientific theories of reproduction that hadn’t really been nailed down at the time—questions that were still being circulated about whether humans could interbreed with animals, for example, and would that produce a monstrous child?

“You look at a some variations of Beauty and the Beast, like Giovan Francesco Straparola’s story of a pig king, where it’s a magical version of these questions, and maybe what’s actually happening is that fairy tales are a way to think through the anxieties and interests of the time.”

Fairy Tales at CU Boulder

The ATU Index is one of the search elements that Suzanne Magnanini and her students are including as they develop the database for Fairy Tales at CU Boulder. The project aims, in part, to improve access and searchability of the more than 2,000 fairy tale collections that are part of the Rare Books Collection at Norlin Library.

The project is a partnership between undergraduates and graduate students under the direction of Magnanini and Sean Babbs, instruction coordinator for the University Libraries' Rare and Distinctive Collections, as well as Hope Saska, CU Art Museum acting director and chief curator, who has trained students in visual-thinking strategies. The project is supported by Undergraduate Research Opportunities Program, the ASSETT Innovation Incubator, the President’s Teaching Scholars Program and the University Libraries.

Fairy Tales at CU Boulder will host a showcase of CU's fairy tale collection from 3:30 to 4:45 p.m. April 16 in Norlin Library M350B. Learn more here.

Though fairy tales may be spun in response to what’s happening in a specific time and place, they also often address concerns that aren’t specific to one location or culture but are broadly pondered across humanity. “Andrew Teverson has written that fairy tales are literature’s migrants because they can move across borders, they can move across boundaries and then make themselves at home and assimilate to a certain extent in different cultures,” Magnanini says.

For example, the Brothers Grimm heard a tale called “Sneewittchen” (Snow White) from folklorist Marie Hassenpflug, as well as from other sources, and included it as tale No. 53 in their seminal 1812 Grimm’s Fairy Tales. However, says Magnanini, there was a similar tale called “The Young Slave” in Giambattista Basile’s 1634 work Pentamerone. In fact, Snow White is type 709 in the Aarne–Thompson–Uther Index (ATU Index), which catalogs and describes common motifs and themes in fairy tales and folklore around the world.

Not so happily ever after

The origins of many fairy tales can be traced as far back as ancient Greece, Rome and China, Magnanini says, which speaks to their ability not only to help people of particular times and places explore their anxieties and questions, but to address the feelings that have been central to the human condition almost since our species emerged from caves.

“When I think about fairy tales, I think about number of characteristics that make them really appealing across time and space,” Magnanini says. “If you think about it, the protagonists are almost always young people heading out into the world—much like our students are heading out—leaving home behind, having to make their way in world, facing challenges. That experience can be very transformational, so in a way these stories are all about metamorphosis and change.

“A lot of times that’s when you’re living your life in Technicolor and all the emotions are new. So, even if you’re no longer in that moment of life, fairy tales tap into experiences like the first falling in love, the first adventure from home. And they often end right after the wedding, so you don’t see someone having to do their taxes or being like, ‘Oh, my god, I’ve been in this relationship for 30 years and I’m bored.’ I think part of the reason we don’t get tired of fairy tales is because they capture this fleeting time in life.”

“If you think about it, the (fairy tale) protagonists are almost always young people heading out into the world—much like our students are heading out—leaving home behind, having to make their way in world, facing challenges," says CU Boulder scholar Suzanne Magnanini. (Photo: Disney Studios)

While fairy tales, particularly as they’ve been interpreted and simplified by Disney, are stereotyped as having “and they lived happily ever after” endings, fairy tales pre-Disney more commonly ended with justice served, Magnanini says. For example, the version of “Snow White” in the 1812 Grimm’s Fairy Tales ends with the evil queen being forced to step into a pair of red-hot iron shoes and dance until she dies.

“A lot of people will say, ‘Oh, it’s the happy ending that’s the appeal of fairy tales,’ but it’s important to remember the vast majority of fairy tales end with the deliverance of justice—something really unjust has happened, someone has been discriminated against, there’s some evil in the world, and justice is delivered,” Magnanini explains. “People who study the formal aspects of fairy tales always talk about how the ‘happy ending’ is found in justice.

“Disney Studios has a tendency to remove the ambiguity from these tales and remove most of the violence—simplifying them in a lot of ways. If you read the French version of Beauty and the Beast, Charles Perrault’s version, there were other siblings in there; there was a complex family structure with complex interactions and a lot of really heavy issues—the family must deal with economic disaster.”

In fact, the field of fairy tale scholarship addresses everything from feminist interpretations of the stories to the ways in which children use fairy tales to help navigate psychosexual rites of passage. Generations of authors have told and continue to retell these familiar stories through different lenses of gender, sexuality, geography, racial identity, economic status and many, many others.

“What makes these stories different, and what I think is a big part of the appeal of fairy tales, is the magic or the marvel,” Magnanini says. “For it to be a fairy tale, scholars would say there has to be magic in there—not just the presence of magic, but magic that facilitates the happy ending by allowing the protagonist to overcome whatever obstacles are in the way of what they desire, maybe the marriage, the wealth, the happy ending. There’s something so satisfying about that, because it doesn’t happen in your quotidian day-to-day life. I mean, imagine if you met a talking deer.”

Picturing climate change in the West Rachel Sauer Wed, 04/02/2025 - 14:57

What began as a hobby for CU Boulder economics undergrad Lucas Gauthier came together as a photographic portfolio documenting the already-evident and potential effects of climate change

Lucas Gauthier and his family moved to Colorado when he was in 6th grade, and after a decade of fairly frequent moves—both parents were in the military—this is where everything made sense: mountains for climbing, runs for skiing, trails for hiking and rivers for rafting.

They took some convincing, but eventually his parents let him venture out on his own—forays that grew longer and longer and took him farther and farther into the Colorado wilderness.

Lucas Gauthier, a senior majoring in economics, has photographically documented his adventures in western landscapes since he was in high school.

��Ƶ four or five years ago, he began taking pictures along the way, usually on his phone. The photography wasn’t the point, necessarily, “but I found that, especially in Colorado, hiking puts you in some very beautiful places,” he explains. “I hike, and the pictures happen while I’m hiking.”

A through line for what had become a large portfolio of photographs emerged in spring 2024. Gauthier, a senior majoring in economics with a focus on natural resource management, was taking ENLP 3100—Complex Leadership Challenges, a class that requires students to complete three projects during the semester.

The first two projects were more technically focused, but the third emphasized creating something of personal value. So, Gauthier thought about all the places in Colorado that he loves, scrolling through both his memories and his photos. He realized that what began as an almost offhanded hobby was actually documenting places that would be or already were altered by climate change.

From that realization was born Climate Change in the West: A Photographic Journal, a multimedia project that incorporates not only data about things like wildfire, heat wave and drought risk and their potential for significant economic impact, but makes it personal with the scenes of incomparable beauty he has witnessed and documented.

“My interest in water specifically came from my interest in hiking and skiing and an interest in all outdoor sports,” Gauthier says. “When people say there’s going to be less rain, less precipitation, that’s a big deal for me.

“I worked and lived in Breckenridge, which is a tourism-dependent area, so if there’s not enough water, that’s weeks of ski season that are lost, and there might not be a rafting season, so that’s where you start to see the overlaps between how climate change is affecting natural systems and the actual economic impacts on livelihoods.”

Capturing what he sees

“My interest in photography has been in capturing this broad swath of environments that we get to play in—as a way to memorialize the experience for myself, and also to share it with others,” Gauthier says.

He took two photography classes in high school, neither of which focused on outdoor or landscape photography, “but I do think those gave me a good idea for how to compose photos and set them up, how to look for different lighting and visual elements,” he says. “They got me in the mindset of thinking, ‘This is something that strikes me, and I’ll see if I can frame it in way that works with what I want to capture.’”

Gauthier was also in high school when he began tackling ever-more-ambitious climbs and started working his way through Colorado’s 58 fourteeners, a goal he completed over the summer. Of those 58, he climbed at least 45 solo.

“(Climbing solo) is kind of a mix of preference and necessity,” Gauthier explains. “It’s easier when the only person you have to plan for logistically is yourself. And when you’re trying to beat lighting and thunder, it’s best to move light and fast.”

However, he never moves so fast that he can’t look around and, if he’s able, to capture what he’s seeing in a photograph. And he returns to certain favorite places, enough that he can compare them season by season or year by year.

“We’ve had a mix of good and bad snow years, but it’s been very noticeable when a particular area that usually has good (snow) coverage into May or June has already melted,” he says. “And there have been times when I’ve hiked through area and a few years later it’s a burn scar, which is a very visceral sense of change in the environment.

“Then there are little things like aspens are yellowing at a different date, wildflowers are blooming and stop blooming at different times. While it’s not as black and white a change, moving those transition points is definitely something that adds up in aggregate.”

Factors of climate change

Now, as he works his way through Colorado’s 100 highest peaks—he’s summited more than 80—and completes his bachelor’s degree, he still is conceptualizing what it all means. Many climate change models are forecast to take decades—if not centuries—to happen, but Gauthier is already seeing anecdotal evidence of them. What does that mean for how he exists in the outdoors and what he’s going to do after he graduates?

“I feel like there is a lot of doom and gloom, and I definitely feel that, but at the same time I am very much a person who feels like I have to say what I’m going to do about it,” he says. “With my area of emphasis in environmental economics, it’s about acknowledging that we have these issues and asking how we address them through actual, tangible means. For me, that means engaging in actual political and broader social processes. When I’m engaged in something, I feel less powerless.

“I think the main point that I wanted to communicate with this project was emphasizing how each of these different factors of climate change are integrated,” he says. “Fires affect water quality, flooding affects agriculture and all of it impacts places that I and a lot of other people love.”

Black History Month celebration emphasizes building the ‘beloved community’ Rachel Sauer Mon, 02/03/2025 - 15:07

While speakers acknowledged the change and uncertainty of the moment, they encouraged hope and the importance of continuing to work toward justice

The afternoon began with a karibu, the Swahili word for “welcome”—not just to the Glenn Miller Ballroom or the ��Ƶ campus, but to the beloved community “where everybody is included and nobody is excluded,” said Reiland Rabaka, founder and director of the Center for African and African American Studies (CAAAS), in opening the CAAAS Day Black History Month celebration Saturday afternoon.

The celebration came, as several of the speakers acknowledged, during a time of great change, when many are feeling the anxiety that often accompanies uncertainty.

CU President Todd Saliman (left) and Reiland Rabaka, Center for African and African American Studies founder and director, emphasized the importance of compassion in the present moment.

“I have spent many decades watching progress and regress,” said CU Boulder Chancellor Justin Schwartz. “We seem to step forward and then back and then forward again.”

In emphasizing the Rev. Dr. Martin Luther King Jr.’s observation that, “The arc of the moral universe is long, but it bends toward justice,” Schwartz noted that the arc “is not smooth like a rainbow,” but rough and jagged. “The arc does not bend on its own, people bend the arc. Collectively, we bend the arc toward justice.”

Todd Saliman, president of the University of Colorado, told those in attendance that “we are not changing anything until we are required to do so by a lawful order. We’ll keep our eye on the ball and continue to do our work. At this point, there’s very little we’ve been required to do lawfully.”

Saliman added that the University of Colorado remains committed to all of Colorado and encouraged people to “approach each other with compassion right now.”

CU Regent Wanda James, the second Black woman and third Black regent in the history of CU, was forceful in pointing out the lack of Black leadership within the CU system, while Annett James, president of the NAACP of Boulder County, emphasized the importance of accurately told history during Black History Month.

“History must be approached as a discipline rooted in fact,” James said, “not interpreted by those who wrote it.”

Boulder Mayor Aaron Brockett, while acknowledging the “struggle, setback and oppression” in Boulder’s history, said that “in the days and years to come, we will continue to build the beloved community here in Boulder.”

Carrying the theme of building the beloved community, Rabaka emphasized that “we are going to keep doing this and we shall not be moved.”

CU Regent Wanda James (center, black baseball cap) observed that "this is a deep Black History Month for us for a lot of reasons."

CU Boulder Chancellor Justin Schwartz emphasized that the "arc (of the moral universe) does not bend on its own, people bend the arc."

Movies did not invent stars—there were stars of theater, opera and vaudeville well before moving pictures—but movies made them bigger and more brilliant; in some cases, edging close to the incandescence of a supernova.

Consider a star like Paul Newman, who would have turned 100 Jan. 26. Despite being an Oscar winner for The Color of Money in 1987 and a nine-time acting Oscar nominee, he was known perhaps even more for the radiance of his stardom—the ineffable cool, the certain reserve, the style, the beauty, the transcendent charisma that dared viewers to look away.

“There are still actors we like and want to go see, so I’d say there still are movie stars but the idea of them has changed,” says CU Boulder film historian Clark Farmer, a teaching assistant professor of cinema studies and moving image arts.

Even now, 17 years after his death in 2008 at age 83, fans still sigh, “They just don’t make stars like that anymore.”

In fact, if you believe the click-bait headlines that show up in newsfeeds every couple of months, the age of the movie star is over. In a 2022 interview with Allure magazine, movie star Jennifer Aniston opined, “There are no more movie stars.” And in Vanity Fair’s 2023 Hollywood issue, star Ana De Armas noted, “The concept of a movie star is someone untouchable you only see onscreen. That mystery is gone.”

Are there really no more movie stars?

“There are still actors we like and want to go see, so I’d say there still are movie stars, but the idea of them has changed,” says ��Ƶ film historian Clark Farmer, a teaching assistant professor of cinema studies and moving image arts. “I think that sense of larger-than-life glamor is gone, that sense of amazement at seeing these people on the screen.

“When we think of what could be called the golden age of movie stars, they had this aristocratic sheen to them. They carried themselves so well, they were well-dressed, they were larger than life, the channels where we could see them and learn about them were a lot more limited. Today, we see stars a lot more and they’re maybe a little less shiny and not as special in that way.”

Stars are born

In the earliest days of film, around the turn of the 20th century, there weren’t enough regular film performers to be widely recognized by viewers, Farmer says. People were drawn to the movie theater by the novelty of moving pictures rather than to see particular actors. However, around 1908 and with the advent of nickelodeons, film started taking off as a big business and actors started signing longer-term contracts. This meant that audiences started seeing the same faces over and over again.

By 1909, exhibitors were reporting that audiences would ask for the names of actors and would also write to the nascent film companies asking for photographs. “Back then you didn’t have credits, you only had the title of the film and the name of the production company, so people started attaching names to these stars—for example, Maurice Costello was called Dimples.”

As the movie business grew into an industry, and as actors were named in a film’s credits, movie stars were born. In 1915, Charlie Chaplin conflagrated across screens not just in the United States, but internationally, Farmer says.

“You could say that what was produced in Hollywood was movies, but studios were also actively trying to produce stars—stars were as much a product as the movies,” Farmer says. “There was always this question of could they take someone who had some talent or some looks or skills like dancing or singing, and would they only rise to the level of extra, would they play secondary characters, or would they become stars? Would people see their name and want to come see the movies they were in?

“Stars have this ineffable quality, and studios would have hundreds of people whose job it was just to make stars; there was a whole machinery in place.”

During Hollywood’s studio period, actors would sign contracts with a studio and the studio’s star machinery would get to work: choosing names for the would-be stars, creating fake biographies, planting stories in fan magazines, arranging for dental work and wardrobes and homes and sometimes even relationships.

For as long as it has existed, the creation and existence of movie stars has drawn criticism from those who argue that being a good star is not the same as being a good actor, and that stars who are bigger than the films in which they appear overshadow all the elements of artistry that align in cinema—from screenwriting to cinematography to acting and directing.

“There’s always been a mixture of people who consider film primarily a business and those who consider it primarily art,” Farmer explains. “Film has always been a place for a lot of really creative individuals who weren’t necessarily thinking of the bottom line and wanted to do something more artistic, but they depended on those who thought about it as a business. Those are the people asking, ‘How do you bring people in to see a movie?’ Part of that can be a recognizable genre, it could be a recognizable property—like a familiar book—but then stars are one more hook for an audience member to say, ‘I like Katherine Hepburn, I like her as an actress and as a person, and she’s in this movie so I’ll give it a try.'

“One of the biggest questions in the film industry is, ‘How can we guarantee people will come see our movie?’ And the gamble has been that stardom is part of that equation.”

Evolving stardom

As for the argument that movie stars cheapen the integrity of cinema, “I don’t think they’re bad for film as an art form,” Farmer says. “Audiences have this idea of who this person is as a star or as a performer, which can make storytelling a lot easier. You have this sense of, ‘I know who Humphrey Bogart is and the roles he plays,’ so a lot of the work of creating the character has already been done. You can have a director saying, ‘I want this person in the role because people’s understanding of who this person is will help create the film.’ You can have Frank Capra cast Jimmy Stewart and the work of establishing the character as a lovable nice guy is already done.”

As the movie industry evolved away from the studio system, the role of the movie star—and what audiences wanted and expected from stars—also began changing, Farmer says. While there was still room for stars who were good at doing the thing for which they were known—the John Waynes who were excellent at playing the John Wayne character—there also were “chameleon” stars who disappeared into roles and wanted to be known for their talent rather than their hair and makeup.

As film evolved, so did technology and culture, Farmer says. With each year, there were more channels, more outlets, more media to dilute what had been a monoculture of film.

“Before everyone had cable and streaming services and social media, movies were much more of a cultural touchpoint,” Farmer says. “People wanted to dress like Humphrey Bogart or Audrey Hepburn. Faye Dunaway wears a beret in Bonnie and Clyde and beret sales go off the charts. People went to the movies, and they recognized and admired these stars.

“One of the markers of stardom is can an individual actor carry a mediocre film to financial success? Another would be, are there people who have an almost obsessive interest in these stars, to the point of modeling themselves after star? Stars tap into a sort of zeitgeist.”

However, the growth and fragmentation of media have meant that viewers have more avenues to see films and more ways to access stars. Even when A-listers’ social media are clearly curated by an army of publicists and stylists, fans can access them at any time and feel like they know them, Farmer says.

“Movies are just less central to people’s lives than they used to be,” Farmer says. “There are other forms of media that people spend their time on, to the point that younger audiences are as likely to know someone who starred in a movie as someone who’s a social media influencer. But that’s just a different kind of stardom.

“I think the film industry really wants movie stars, but I’m not sure viewers necessarily care all that much. Again, it’s always the question of, if you’re spending millions and millions of dollars on a product and you want a return on that, how can you achieve that without making another superhero movie or another horror movie? The industry wants movie stars and audiences just want to be entertained.”
