Simulations of Exoplanet Formation May Help Inform Search for Extraterrestrial Life

Florida Tech astrophysicist Howard Chen is offering new insights to help aid NASA’s search for life beyond Earth. His latest theoretical work investigates the TRAPPIST-1 planetary system, one of the most widely studied exoplanetary systems in the galaxy. It has captured scientists’ attention for its potential to host water, and thus possibly life, on its planets. Now, he’s offering an explanation for why telescopes have yet to find definitive signs of either. The paper “Born Dry or Born Wet? A Palette of Water Growth Histories in TRAPPIST-1 Analogs and Compact Planetary Systems” was authored by Chen, an assistant professor of space sciences, and researchers from NASA, Johns Hopkins University and Harvard University, was published in The Astrophysical Journal Letters in September. It explores the likelihood that TRAPPIST-1’s three innermost exoplanets contained no water when they formed, despite existing in a zone where water is viable. TRAPPIST-1 is a red dwarf star located about 40 light-years away from us. (One light year is about 6 trillion miles.) It is thought to be about 7.6 billion years old, or 3 billion years older than our Sun. Astronomers are captivated by the TRAPPIST-1 system because its seven known planets are rocky and Earth-like. They also fall within the star’s habitable zone: the distance range from a star at which temperatures are not too hot or cold to support liquid water. Researchers are searching for any evidence of water on these planets, but have yet to detect anything. Some think a lack of gas in the atmosphere is disrupting the light needed to pick up detailed visuals. Others predict water could have escaped the planets’ atmospheres throughout their evolution. Chen and his team, however, decided to research a different theory: that there was no water to begin with because there was no gas to contain it. He would test it not from an observational perspective, but with mathematical modeling of the planets’ initial formation. “You have astronomers who are using telescopes to see what’s out there. I come from a different perspective,” Chen said. “I’m both trying to explain what we’re seeing while trying to make predictions about what we can’t.” The researchers created models that examined the composition and growth of these planets starting when they were as small as one kilometer wide. They simulated how material aggregated during collisions with other celestial objects until they reached their final planetary formations. There are several key factors in collision events that heavily influence a planet’s final composition. Chen’s models incorporated impact delivery, which is the transfer of materials like water and gases during a celestial collision; impact erosion, which refers to the removal of materials in a planet’s atmosphere due to impact; and mantle-atmosphere exchange, which is the transfer of water and gases between a planet’s atmosphere and mantle to maintain its conditions. The team ran hundreds of collision simulations, which returned thousands of different possibilities for how TRAPPIST-1’s planets might have formed. They varied several components, such as the amount of water available to the system, the profile of the initial planet formation environment, the planets’ density profiles and the initial system conditions. For the inner worlds, specifically the first three planets, most of the simulations came back dry. “Whatever we did, we couldn’t get much water in these inner planets,” Chen said. He believes that the main reason the planets couldn’t acquire water is due to the nature of the collision events. Compact planet collisions are higher velocity, so they are more aggressive and energetic, Chen said. This means that instead of acquiring material for a gaseous atmosphere, planets’ atmospheres were completely cleared out by the power of the collisions. With no gas in the atmosphere to contain water, it’s possible that any previously existing water escaped back into space during these collision events. Understanding a planet’s earliest characteristics, its water, air and carbon content, builds the foundation for how they evolve. That way, when researchers identify a planet that seems viable for life at the surface level, they can use Chen’s model to simulate what these distant worlds might be like on the inside, on the surface and in the air. Combining the theoretical context of a planet’s formation with the state in which it was discovered can help researchers – and NASA – make informed, efficient decisions on which planets are worth investigating and when it’s time to move on to the next.

Expert Research: The Fourth Industrial Revolution, Artificial Intelligence and Domestic Conflict featured image

Expert Research: The Fourth Industrial Revolution, Artificial Intelligence and Domestic Conflict

Artificial Intelligence is often framed as a driver of innovation. But it also has the power to disrupt the very foundations of our societies. In a recent study, experts Craig Albert, PhD, and Lance Hunter, PhD, from Augusta University explored how AI, as part of the Fourth Industrial Revolution, could reshape economies, politics and security within states. Here are three key takeaways from the research: AI brings breakthroughs in health care, logistics and engineering, but also disrupts jobs and economies. Unmanaged disruption can fuel instability, widening inequality and increasing risks of unrest or domestic conflict. Governments must act now with retraining, adaptive policies and strong governance to harness AI’s benefits while reducing risks. Lance Hunter, PhD, is an assistant professor of political science with a background in international relations. His research focuses on how terrorist attacks influence politics in democratic countries and how political decisions within countries affect conflicts worldwide. Hunter teaches courses in international relations, security studies and research methods. He received his PhD in Political Science from Texas Tech University in 2011.   View his profile here. Craig Albert, PhD, is a professor of Political Science and the graduate director of the PhD in Intelligence, Defense, and Cybersecurity Policy and the Master of Arts in Intelligence and Security Studies at Augusta University. His areas of concentration include international security studies, cybersecurity policy, information warfare/influence operations/propaganda, ethnic conflict, cyberterrorism and cyberwar, and political philosophy. View his profile here. The question we face is not whether AI will transform society (it already is!) but how we will manage that transformation to strengthen rather than destabilize. What steps do you think policymakers should prioritize to prepare for this future? Here's the abstract from the paper in Research Gate: An emerging field of scholarship in Artificial Intelligence (AI) and computing posits that AI has the potential to significantly alter political and economic landscapes within states by reconfiguring labor markets, economies and political alliances, leading to possible societal disruptions. Thus, this study examines the potential destabilizing economic and political effects AI technology can have on societies and the resulting implications for domestic conflict based on research within the fields of political science, sociology, economics and artificial intelligence. In addition, we conduct interviews with 10 international AI experts from think tanks, academia, multinational technology companies, the military and cyber to assess the possible disruptive effects of AI and how they can affect domestic conflict. Lastly, the study offers steps governments can take to mitigate the potentially destabilizing effects of AI technology to reduce the likelihood of civil conflict and domestic terrorism within states.

MSU researchers develop wood-based material that improves safety and life of lithium-ion batteries featured image

MSU researchers develop wood-based material that improves safety and life of lithium-ion batteries

For consumers worried about the risks associated with using lithium-ion batteries — which are used in everything from phones to laptops to electric vehicles — Michigan State University has discovered that a natural material found in wood can improve battery safety while also improving the battery’s life. Chengcheng Fang, assistant professor in the College of Engineering, and Mojgan Nejad, an associate professor in the College of Agriculture and Natural Resources, collaborated to engineer lignin, a natural ingredient of wood that provides support and rigidity, into a thin film separator that can be used inside lithium-ion batteries to prevent short circuits that can cause a fire. “We wanted to build a better battery,” said Fang. “But we also wanted it to be safe, efficient and sustainable.” Inside a battery, the positively charged cathode and negatively charged anode electrodes help the flow of electricity. To keep these electrodes apart, a commercial separator is typically made from polyethylene and polypropylene plastic materials, which can shrink at temperatures near 100 degrees Celsius. Without the protection of the separator, the cathode and anode sides of the battery have the potential to touch, causing an accidental short circuit and possible fire or explosion. In contrast, the lignin-based separators developed remained stable and didn’t become smaller in size up to temperatures of 300 degrees Celsius. Fang and her team tested varying thicknesses of lignin and found that films measuring 25 micrometers, which is thinner than one quarter of a human hair, were the most effective at keeping the inside of the battery stable and keeping the anode and cathode from connecting. Using the lignin film inside the battery had another benefit: the increased stability inside the battery also resulted in an improved cycle life, or how many times the battery can be charged and used. “We were surprised to see that the lignin film also improved the battery’s cycle life,” said Fang. “We increased the battery’s cycle life by 60%.” A third advantage of this research is an environmentally friendly one. The team was able to manufacture the lignin separators using a low-cost dry processing method. This meant that the team was able to produce large quantities of the lignin film, on demand, while avoiding the use of harmful solvents commonly used in traditional separator manufacturing, which can be harmful to the environment. In this case, the researchers were able to use lignin and other materials that provided a 100% raw material conversion to create a film without creating any waste or pollution. “Lignin, particularly lignosulfonate, is naturally abundant and it doesn’t need any further treatment to function in batteries,” said Fang. “This work demonstrates a new design pathway to improve both the safety and manufacturability of battery materials.” This research was published in Advanced Materials, and the technology is patent pending through the MSU Innovation Center.

Deaf children share insights on what researchers should study next in Aston University co-led project featured image

Deaf children share insights on what researchers should study next in Aston University co-led project

Aston University’s Dr Amanda Hall co-led the study with Dr Anisa Visram from the University of Manchester Deaf children and those with experience of childhood deafness have identified their top 10 research priorities including education and family relationships The project was funded by the National Deaf Children’s Society Deaf children and people with experience of childhood deafness from across the UK have come together to highlight what matters most to children affected by deafness and hearing loss, as part of a project funded by the National Deaf Children’s Society (NDCS). From 2023 to 2025, a team of parents, young people and health and education professionals set out to compile a list of the ‘Top 10’ most important questions that researchers should be trying to answer about childhood deafness and hearing loss. The project was co-led by Dr Amanda Hall, a senior lecturer in audiology at Aston University, and Dr Anisa Visram from the University of Manchester in conjunction with researchers at Lancaster University. The hope is that it will ultimately lead to more research into childhood deafness, in the specific areas it’s needed most. Children highlighted the potential impact of them missing out on things happening around them when interacting with their peers as their top priority, demonstrating the importance of social development for deaf children. Family relationships and educational needs ranked as high priorities for both adults and children, coming in the top 3 for both groups. Adults ranked educational needs as number 1, highlighting the importance of supporting deaf children in schools, particularly those with additional needs. Other important areas for research included understanding what support is needed for children with mild and unilateral (on one side) deafness, the impact of language deprivation on deaf children and how deaf children can be supported to understand their deafness and become empowered to advocate for themselves as they grow up into deaf adults. Several hundred respondents contributed to the project through a series of online surveys. Children were involved through activity-based focus groups. Respondents submitted over 1,200 ideas for research questions in the initial surveys. These were summarised into a list of 59 unique questions, and a second survey was used to prioritise the questions. The top 21 questions were then taken to two final full-day workshop where participants collaborated to choose their top 10 priorities. The research team used what’s known as a James Lind Alliance (JLA) priority-setting process to ensure the robustness of the project. Participants reported feeling valued as part of the project and satisfied that their feedback is reflected in the final lists. One of the children who took part in the workshop said: “I learnt that my voice matters and I can make a difference for me and other deaf children.” Dr Hall said: “It has been a real privilege to be part of this JLA partnership, working alongside deaf young people, families of deaf children and professionals to identify our two sets of top 10 research questions. We hope this is just the beginning of more research that reflects what matters most to deaf children, their families and professionals, and of more opportunities to work together.” Dr Visram said: “This has been an incredible project to work on with an amazing, committed, and diverse stakeholder group feeding into the process at all stages. We have formed important collaborations with deaf young people, parents of deaf children, and a whole range of professionals working with deaf children. The group plan to keep working together to promote the Top 10 lists and help develop research projects to start to answer these important questions.” Juliet Viney is a parent to a deaf child and has supported the project as a parent partner. She said: “It has been an absolute privilege working as a parent partner developing our Top 10 most important research questions for childhood deafness. This project has brought together and empowered deaf children and young people, parents and professionals from across the UK; using their valuable lived experiences to provide them with a strong voice to guide researchers towards addressing what is most needed to improve deaf children's educational, health, social and emotional outcomes. I am excited to see which questions will be pursued in further research and the positive impacts these will have on the lives of deaf children!” Dr Sian Lickess, Research and Analysis Lead at the National Deaf Children’s Society, said: “We are proud to have supported this important partnership, which has brought together the voices of deaf children, their families and professionals to shape future research priorities. The resulting Top 10 lists represent an important step toward ensuring research is aligned with real-world needs and is meaningful to those most affected. We look forward to the impact this work will have on improving outcomes for deaf children.” The full list of priorities identified can be found at: www.childdeafnessresearch.co.uk. As well as the National Deaf Children’s Society, several other partners have also contributed to the project. These include the Professor Kevin Munro’s National Institute for Health and Care Research (NIHR) Senior Investigator award, NIHR Manchester Biomedical Research Centre, PF Charitable Trust, Research England’s QR Participatory Research Fund to Lancaster University, and UKRI Future Leaders Fellowship MR/X035999/1.

America's literacy emergency continues; experts available with solutions featured image

America's literacy emergency continues; experts available with solutions

September is more than back-to-school season. It is also National Literacy Month. This return to the classroom and yearly recognition remind us of the urgent need to ensure every child has the literacy skills to thrive in school and beyond. One such example of this is Delaware.  Despite recent gains in statewide test scores, Delaware leaders have warned: a literacy emergency persists. Too many children – especially those from marginalized communities – are still being left behind in reading proficiency. The University of Delaware’s College of Education and Human Development is helping to change that. CEHD’s literacy experts are advancing research, building partnerships, and equipping educators with evidence-based strategies that make an impact. Annastasia Purinton and Steve Amendum work with the WTG Foundation to strengthen school-community partnerships that bring literacy support directly to students who need it most. Stephanie Del Tufo, whose recent essay in The Conversation spotlighted the science of reading, studies how early learning and memory processes shape literacy development. Adrian Pasquarella focuses on multilingual learners, helping educators bridge language learning and literacy growth – an area of growing importance in Delaware’s diverse classrooms. Rebecca Joella and colleagues at the Delaware Institute for Excellence in Early Childhood are leading professional development efforts that equip early educators to foster strong literacy skills from the start. These experts bring research to life – translating what works in the classroom into scalable practices and policies. Their work underscores a powerful truth: literacy is not just an academic milestone, it is the foundation for opportunity, equity and lifelong success. As Delaware and the nation confront the literacy crisis, CEHD stands at the forefront with the evidence, expertise and partnerships to make a lasting difference.

Ask an Expert: Augusta University's Gokila Dorai, PhD, talks Artificial Intelligence

Artificial Intelligence is dominating the news cycle. There's a lot to know, a lot to prepare for and also a lot of misinformation or assumptions that are making their way into the mainstream coverage. Recently, Augusta University's Gokila Dorai, PhD, took some time to answer some of the more important question's she's seeing being asked about Artificial Intelligence. Gokila Dorai, PhD, is an assistant professor in the School of Computer and Cyber Sciences at Augusta University. Dorai’s area of expertise is mobile/IoT forensics research. She is passionate about inventing digital tools to help victims and survivors of various digital crimes. View her profile here Q. What excites you most about your current research in digital forensics and AI? "I am most excited about using artificial intelligence to produce frameworks for practitioners make sense of complex digital evidence more quickly and fairly. My research combines machine learning with natural language processing incorporating a socio-technical framework, so that we don’t just get accurate results, but also understand how and why the system reached those results. This is especially important when dealing with sensitive investigations, where transparency builds trust." Q. How does your work help address today’s challenges around cybersecurity and data privacy? "Everyday life is increasingly digital, our phones, apps, and online accounts contain deeply personal information. My research looks at how we can responsibly analyze this data during investigations without compromising privacy. For example, I work on AI models that can focus only on what is legally relevant, while filtering out unrelated personal information. This balance between security and privacy is one of the biggest challenges today, and my work aims to provide practical solutions." Q. What role do you see artificial intelligence playing in shaping the future of digital investigations? "AI will be a critical partner in digital investigations. The volume of data investigators face is overwhelming, thousands of documents, chat messages, and app logs. AI can help organize and prioritize this information, spotting patterns that a human might miss. At the same time, I believe AI must be designed to be explainable and resilient against manipulation, so investigators and courts can trust its findings. The future isn’t about replacing human judgment, but about giving investigators smarter tools." Q. What is one misconception people often have about cybersecurity or digital forensics? "A common misconception is that digital forensics is like what you see on TV, instant results with a few keystrokes. In reality, it’s a painstaking process that requires both technical skill and ethical responsibility. Another misconception is that cybersecurity is only about protecting large organizations. In truth, individuals face just as many risks, from identity theft to app data leaks, and my research highlights how better tools can protect everyone."

How to respond when your teen rebels featured image

How to respond when your teen rebels

Why do some rebellious teenagers shun parental warnings about their behavior while others take them to heart? University of Rochester psychologist Judith Smetana has devoted her career to unpacking that question. Her research reveals that parents who live out their values — and take the time to understand the perspective of their teenagers — have the most success at positively shaping adolescent behavior. Smetana’s latest study, published in the Journal of Youth and Adolescence, shows that when parents “walk the walk” and model their values consistently, teens perceive rules and warnings as supportive guidance rather than controlling commands. But that alone won’t stop all risky teenage behavior. What really works, Smetana’s research finds, is “perspective-taking”: when parents try to understand their child’s feelings and the reasons for them. Smetana is widely cited for her expertise on moral development, autonomy, and parent-teen conflict — and how these dynamics shape young people’s lives. Connect with her by clicking on her profile.

Swimming in the deep: MSU research reveals sea lamprey travel patterns in Great Lakes waterways featured image

Swimming in the deep: MSU research reveals sea lamprey travel patterns in Great Lakes waterways

Why this matters: Invasive sea lampreys prey on most species of large Great Lakes fish such as lake trout, brown trout, lake sturgeon, lake whitefish, ciscoes, burbot, walleye and catfish. These species are crucial to Great Lakes ecosystems and to the region’s fishing industry. Understanding how sea lampreys migrate can inform management and conservation strategies, such as developing methods to catch the invasive fish that don’t involve dams, which reduce river connectivity, or lampricide, a pesticide that some communities and groups prefer not to use. The Great Lakes fishing industry is worth $7 billion and provides 75,000 jobs to the region. Reducing the amount of sea lamprey in waters is crucial for the industry’s well-being and the economic vitality of the Great Lakes. How do you catch an invasive fish that’s solitary, nocturnal and doesn't feed on bait? Researchers in the Michigan State University College of Agriculture and Natural Resources are one step closer to figuring it out. In a study published in the Journal of Experimental Biology and funded by the Great Lakes Fishery Commission, Kandace Griffin, a fisheries and wildlife doctoral student, and Michael Wagner, professor in the MSU Department of Fisheries and Wildlife, found that sea lampreys — a parasitic fish considered an invasive species in the Great Lakes region of the U.S. — follow a clear pattern of staying in the deepest parts of a river. These findings are important for informing sea lamprey management strategies, conservation of fish species native to the Great Lakes and protecting the region’s $7 billion fishing industry and the 75,000 jobs it provides. “We wanted to know how sea lampreys are making their movement decisions when migrating,” Griffin said. “Are they guided by certain environmental cues? Are they moving through areas that are safer? How can we potentially exploit those decisions or maybe manipulate them into going somewhere that they don’t want to go, like pushing them into a trap.” The primary methods used to control sea lamprey are dams that block them from entering waterways and lampricide, a species-specific pesticide that targets lamprey larvae. “Dams create a lot of challenges for conserving river ecosystems: They block all the other fish that are moving up and down in the system. Even though lampricide is proven to be safe and effective, there are communities that are uncomfortable with its use going into the future,” Wagner said. “Figuring out the right way to fish sea lamprey would decrease its population, lower reproduction rates and provide managers with the opportunity to match their control tactics to the community’s needs.” To track lamprey movements, Griffin and Wagner used a method called acoustic telemetry, which involved using sound emitted from a surgically implanted tag to track the movement of 56 sea lampreys in the White River near Whitehall, Michigan. Griffin likened acoustic telemetry to GPS. “There’s a tag that emits sound and has a unique transmission with a unique identification code, so I know exactly which fish is going where,” she said. “The receivers are listening for that sound and then calculating the time it reaches each receiver. We used this information to triangulate the position of the sea lamprey and analyzed it to find out how they’re using the river’s environmental traits to make decisions on where to swim.” Of the 56 lampreys studied, 26 of them (46%), consistently chose the deepest quarter of the river. “For nearly 20 years we have been discovering how sea lampreys migrate along coasts and through rivers. Now, thanks to Kandace’s work, we know where their movement paths come together near a riverbank — the perfect place to install a trap or other fishing device,” Wagner said. “That knowledge can be used to find similar sites across the Great Lakes basin.” Right now, a fishing device designed to catch bottom-swimming, solitary, nonfeeding, nocturnal sea lamprey doesn’t exist. However, Wagner notes there are places around the world — including Indigenous communities in the U.S. — where people have fished migratory lampreys of various species for hundreds of years and could help inform the creation of such a mechanism. “We have recently had a proposal funded to scour the Earth in search of knowledge, both scientific and traditional, about how to capture migrating lampreys and similar fishes,” Wagner said. “We want to talk with the communities of people who have histories fishing these animals and use this information, along with other data we’ve gathered, to conceive a device that could be used to fish sea lampreys.” Griffin views the new intel on lamprey migration patterns as a way to inform fishing practices to complement some of the existing control methods. “Hopefully, we can use this as a supplemental control method to the use of the barriers or dams,” she said. “We have societal pressure to remove barriers to enhance river connectivity, and some barriers are failing. Open water trapping is another way that we could try to still combat the invasive sea lamprey problem here but also promote river connectivity and other conservation goals for other species.” Wagner shares the same perspective. “When a community, or the Great Lakes Fishery Commission, or the governments of Canada and the U.S. come in and say, ‘We’d really rather be able to control this river with something other than lampricide,’ we want to be able to be able to provide 360-degree solutions that specify where to fish, when to fish and how to fish using fully prototyped and tested equipment,” he said. “We want our science to help solve real-world problems.”

First scientific paper on 3I/ATLAS interstellar object featured image

First scientific paper on 3I/ATLAS interstellar object

When the news started to spread on July 1, 2025, about a new object that was spotted from outside our solar system, only the third of its kind ever known, astronomers at Michigan State University — along with a team of international researchers — turned their telescopes to capture data on the new celestial sighting. The team rushed to write a scientific paper on what they know so far about the object, now called 3I/ATLAS, after NASA’s Asteroid Terrestrial-impact Last Alert System, or ATLAS. ATLAS consists of four telescopes — two in Hawaii, one in Chile and one in South Africa — which automatically scans the whole sky several times every night looking for moving objects. MSU’s Darryl Seligman, a member of the scientific team and an assistant professor in the College of Natural Science, took the lead on writing the paper. “I heard something about the object before I went to bed, but we didn’t have a lot of information yet,” Seligman said. “By the time I woke up around 1 a.m., my colleagues, Marco Micheli from the European Space Agency and Davide Farnocchia from NASA’s Jet Propulsion Laboratory, were emailing me that this was likely for real. I started sending messages telling everyone to turn their telescopes to look at this object and started writing the paper to document what we know to date. We have data coming in from across the globe about this object.” The discovery Larry Denneau, a member of the ATLAS team reviewed and submitted the observations from the European Southern Observatory's Very Large Telescope in Chile shortly after it was observed on the night of July 1. Denneau said that he was cautiously excited. “We have had false alarms in the past about interesting objects, so we know not to get too excited on the first day. But the incoming observations were all consistent, and late that night it looked like we had the real thing. “It is especially gratifying that we found it in the Milky Way in the direction of the galactic center, which is a very challenging place to survey for asteroids because of all the stars in the background,” Denneau said. “Most other surveys don't look there.” John Tonry, another member of ATLAS and professor at the University of Hawaii, was instrumental in design and construction of ATLAS, the survey that discovered 3I. Tonry said, “It's really gratifying every time our hard work surveying the sky discovers something new, and this comet that has been traveling for millions of years from another star system is particularly interesting.” Once 3I/ATLAS was confirmed, Seligman and Karen Meech, faculty chair for the Institute for Astronomy at the University of Hawaii, both managed the communications flow and worked on getting the data pulled together for submitting the paper. “Once 3I/ATLAS was identified as likely interstellar, we mobilized rapidly,” Meech said. “We activated observing time on major facilities like the Southern Astrophysical Research Telescope and the Gemini Observatory to capture early, high-quality data and build a foundation for detailed follow-up studies.” After confirmation of the interstellar object, institutions from around the world began sharing information about 3I/ATLAS with Seligman. What scientists know about 3I/ATLAS so far Though data is pouring in about the discovery, it’s still so far away from Earth, which leaves many unanswered questions. Here’s what the scientific team knows at this point: It is only the third interstellar (meaning from outside our solar system) object to be detected passing through our solar system. It’s potentially giving off gas like other comets do, but that needs to be confirmed. It’s moving really fast at 60 kilometers per second, or 134,000 miles per hour, relative to the sun. It’s on an orbital path that is shaped like a boomerang or hyperbola. It’s very bright. It’s on a path that will leave our solar system and not return, but scientists will be able to study it for several months before it leaves. The James Webb Space Telescope and the Hubble Space Telescope are expected to reveal more information about its size, composition, spin and how it reacts to being heated over the next few months. “We have these images of 3I/ATLAS where it’s not entirely clear and it looks fuzzier than the other stars in the same image,” said James Wray, a professor at Georgia Tech. “But the object is pretty far away and, so, we just don’t know.” Seligman and his team are specifically interested in 3I/ATLAS’s brightness because it informs us about the evolution of the coma, a cloud of dust and gas. They’ve been tracking it to see if it has been changing over time as the object moves and turns in space. They also want to monitor for sudden outburst events in which the object gets much brighter. “3I/ATLAS likely contains ices, especially below the surface, and those ices may start to activate as it nears the sun,” Seligman said. “But until we detect specific gas emissions, like H₂O, CO or CO₂, we can’t say for sure what kinds of ice or how much are there.” The discovery of 3I/ATLAS is just the beginning. For Tessa Frincke, who came to MSU in late June to begin her career as a doctoral student with Seligman, having the opportunity to analyze data from 3I/ATLAS to predict its future path could lead to her publishing a scientific paper of her own. “I’ve had to learn a lot quickly, and I was shocked at how many people were involved,” said Frincke. “Discoveries like this have a domino effect that inspires novel engineering and mission planning.” For Atsuhiro Yaginuma, a fourth-year undergraduate student on Seligman’s team, this discovery has inspired him to apply his current research to see if it is possible to launch a spacecraft from Earth to get it within hundreds of miles or kilometers to 3I/ATLAS to capture some images and learn more about the object. “The closest approach to Earth will be in December,” said Yaginuma. “It would require a lot of fuel and a lot of rapid mobilization from people here on Earth. But getting close to an interstellar object could be a once-in-a-lifetime opportunity.” “We can’t continue to do this research and experiment with new ideas from Frincke and Yaginuma without federal funding,” said Seligman, who also is a postdoctoral fellow of the National Science Foundation. Seligman and Aster Taylor, who is a former student of Seligman’s and now a doctoral candidate in astronomy and astrophysics and a 2023 Fannie and John Hertz Foundation Fellow, wrote the following: “At a critical moment, given the current congressional discussions on science funding, 3I/ATLAS also reminds us of the broader impact of astronomical research. An example like 3I is particularly important to astronomy — as a science, we are supported almost entirely by government and philanthropic funding. The fact that this science is not funded by commercial enterprise indicates that our field does not provide a financial return on investment, but instead responds to the public’s curiosity about the deep questions of the universe: Where did we come from? Are we alone? What else is out there?
