Spotlight on Astronomer Laurie Rousseau-Nepton

Dr. Laurie Rousseau-Nepton made history when she became the first Indigenous woman in Canada to obtain her PhD in astrophysics. Since Rousseau-Nepton finished her doctoral dissertation and graduated from Université Laval in 2017, she has forged her own path as an astronomer and a science communicator.

Rousseau-Nepton worked as a Resident Astronomer at the Canada-France-Hawaii Telescope for six years. Her work as the principal investigator of SIGNALS (Star Formation, Ionized Gas, and Nebular Abundance Legacy Survey) drew enough attention that the National Film Board of Canada made a short five episode docuseries of Rousseau-Nepton's life and work on the project.

Since then, Rousseau-Nepton joined the Dunlap Institute for Astronomy and Astrophysics at the University of Toronto, where she continues to explore the universe, teach, and find ways to communicate science to the community.

She received the Qilak Award in 2023 from the Canadian Astronomical Society for her outstanding contributions to astronomy education and outreach. One of Rousseau-Nepton's favorite topics is how her research aligns with Innu traditions, which says that humans originate from and return to the stars.

In September 2026, the University of Toronto announced Rousseau-Nepton was one of eight recipients of the Connaught Community Partnership Research Program Awards. With the award money, Rousseau-Nepton will continue her current research into how ancient Indigenous peoples observed, understood, and tracked celestial events using stone circle alignments.

On October 16, 2026, Rousseau-Nepton and a team of astronomy students will present Aurora Ancestors & Teachings of the North at Calgary's Telus Spark Science Center. The science center is hosting Stones, Stories, & Stars: Experience Astronomy from the Stone Ancestors. This evening of astronomy and explorations into indigenous oral storytelling takes place from 5 p.m. to 11 p.m.

Emily Calandrelli: 100th Woman in Space

On November 24, 2024, Emily Calandrelli, an aerospace engineer and popular science communicator, became the 100th woman to reach space. Calandrelli joined five other passengers on Blue Origin’s ninth space tourism flight. Blue Origin streamed the launch and Calandrelli’s reaction, which brought hundreds of supportive comments online, but Calandrelli also received some toxic and sexist comments disparaging her response.

Seeing our planet for the first time, a dream decades in the making.

You’re seeing so many emotions intertwined. Excitement, awe, and pride - but to be honest a little fear and confusion too. You just launched on a rocket and you’re seeing something you’ve never seen before… pic.twitter.com/HlL85ENshC

Calandrelli received degrees in Mechanical and Aerospace Engineering from the University of West Virginia. She then attended MIT and earned master’s degrees in Aeronautics and Astronautics and Technology and Policy in 2013. Calandrelli also interned at NASA. 

Since 2013, Calandrelli has worked as a science communicator, advocating for STEM education, particularly for girls, through various media. She is the host of Xploration Outer Space, part of Fox’s Xploration Station, which targets pre-teens and teens with mainly STEM-based programs. Calandrelli had already filmed YouTube videos with the engineering department at the University of West Virginia and had a growing online following as The Space Gal on her social media channels when Fox tapped her to host the program.

Calandrelli also pursued writing with Ada Lace, a STEM adventure series for kids. This six-book series follows 8-year-old Ada Lace as she uses science to solve problems. Calandrelli has also written a picture book, Reach For The Stars, and two science experiment books for kids. 

In 2020, Calandrelli took her passion for STEM education a step further. She pitched the idea for a children’s science show to Netflix and the company picked up the show. Calandrelli, who was pregnant with her first child, got to choose whether she wanted to film the series pregnant or wait until after delivery. The science communicator took the opportunity to film the entire series of Emily’s  Wonder Lab while 36 weeks pregnant.

In an interview with Parentaly, Calandrelli said, “On TV, you don’t usually see someone who is pregnant doing something other than being an expectant mother - or hiding it.” While the show wasn’t renewed for a second season, it still ranks high on Netflix’s list of shows. 

Calandrelli has continued to support STEM education and careers for girls and women through her YouTube channel, recently launching Emily’s Science Lab, where she demonstrates science experiments for kids. Calandrelli also maintains active social media accounts on Instagram, Facebook, X, TikTok, and Bluesky, where she reaches several million followers as The Space Gal.

When Calandrelli traveled past the Kármán line in November, fulfilling a long-held dream to travel to space, she posted her reactions online, despite the risk of all-too-familiar disparaging comments from internet trolls.  Calandrelli posted on Instagram, “I refuse to give much time to the small men on the internet.” Instead, she continues to focus her efforts on advocating for STEM and space exploration for all, particularly for girls and women.

Crosspost: Physicists turn to TikTok for science communication

Written by Madison Brewer for Physics Today

Kirsten Banks is a physics graduate student at the University of New South Wales in Australia and creator of the popular TikTok account, @astrokirsten, on all things astrophysics.

When the pandemic hit, Kirsten Banks missed speaking to audiences. A physics PhD student at the University of New South Wales in Australia, she was used to giving educational astronomy talks regularly at elementary and secondary schools and at public events. When those engagements were canceled, she turned to social media to continue her science outreach.

“I started doing science communication on social media by joining Twitter and making a Facebook page and an Instagram page,” Banks says. Then her partner introduced her to TikTok.

TikTok launched internationally in 2017. In contrast to Twitter, which features mostly written text, and Instagram, which consists primarily of images, TikTok users can post only short videos. If Twitter is like writing a pithy summary, TikTok is akin to giving a short, catchy talk with audiovisual aids. The platform is most popular with teenagers and young adults; in a survey conducted earlier this year, nearly half of US adults ages 18–29 reported using the service, compared with 22% of those 30–49 and 4% of people 65 and over.

Astronomers for Planet Earth: Michelle Willebrands

This feature is part of our ongoing series about the amazing women at Astronomers for Planet Earth (A4E), a global network of astronomers and astronomy enthusiasts dedicated to offering their unique perspective to the fight for climate justice. For this post, we'll hear from Michelle Willebrands, a project officer for the European Regional Office of Astronomy for Development (E-ROAD).

If you're interested in learning more about A4E's work combating global climate change and want to get involved, join them here at: https://astronomersforplanet.earth/join-us-1. And be sure to check out A4E's white paper on what astronomers (like you!) can do to address the climate crisis: Astronomers for Planet Earth: Engaging with the Public to Forge a Sustainable Future.

Michelle Willebrands is a project manager with E-ROAD with a focus on forging partnerships between European and African scientists.

What is your current career and how did you end up there?
I am the coordinator of the International Astronomical Union’s European Regional Office of Astronomy for Development (IAU E-ROAD) based at Leiden, the Netherlands. I did a master’s degree in astronomy and decided to specialize in science communication. During this specialization, I got the chance to work at the headquarters of this office in Cape Town and learn about the field of astronomy for development. After my studies, applying for this position was a great opportunity to continue working in this niche within astronomy and I was lucky enough to get the position. Now, I look at how astronomy can contribute to the UN Sustainable Development Goals and set up projects and collaborations to do so.

What is your role in Astronomers for Planet Earth (A4E)?
I have been involved fairly early on when the European chapter was established. I try to help out with the operations and across the various projects, including for example the recent Open Letter initiative. In general, I also try to connect A4E with the global network of the IAU Office of Astronomy for Development (OAD) that I am part of. Climate change and sustainability are crucial topics when addressing the sustainable development goals (SDGs), so this connection between A4E and the OAD is a very natural one to me.

What goals do you have for your role in A4E?
At A4E, I hope that I can keep contributing with the expertise and network that I have. One thing that matters to me a lot is the social justice aspect of the climate crisis. Currently, A4E does not represent astronomers from all over the world, although we are trying to engage with astronomers everywhere. I hope that we can achieve creating a diverse network with voices from all backgrounds and perspectives in the near future.

Describe the first time you made a personal connection between your passion for astronomy and the urgency of fighting climate change.
Climate change was a topic that I think I always connected to astronomy in outreach, but the time that the urgency of the climate crisis really hit me may actually coincide with that of some of the other members from Europe. One of the first conferences I attended in my current position was the 2019 annual meeting of the European Astronomical Society in Lyon, France, during which there was a heatwave. To try and keep the attendants comfortable there were plastic bottles with water everywhere you looked but it was still unpleasant to be with so many people in an old building. The combination of the extreme heat, the plastic litter and the fact that so many people had travelled (by train or airplane) to take part in the conference felt a bit ridiculous and almost immoral. It was during this conference that the precursor of what is now the European A4E chapter was first raised and I joined briefly afterwards.

How does your career in astronomy intersect with the fight against climate change?
In my position of E-ROAD coordinator, I am lucky enough that I can look at astronomy in the broadest sense possible: as a research field, in education and public engagement, the benefits it brings to society, but also the challenges we face in sustainable development and the role that scientists can play to address them. This means that I consider the work I do with A4E and combating climate change as a part of my astronomy career. Specifically, this translates to an educational program that we are setting up for young children called Pale Blue Dot. In this project, we use the awe-inspiring images of Earth as seen from space to teach children across the globe about the interconnectedness of our home planet and the need to work together in solidarity to protect it. Astronomy can offer a very powerful perspective on the uniqueness of the Earth and its climate which can be used in education and science communication to engage people everywhere in the fight against climate change.

How can the astronomical community engage with the climate crisis movement?
As scientists, astronomers understand the science behind climate change and the urgency to act now. The astronomical community, like any scientific community, can be a role model in handling the climate crisis by changing their own behaviors on one hand and by engaging with the public to talk about climate change on the other. Astronomy is a field of research that has a relatively high footprint, so the astronomical community needs to reflect on the way that research is being done and adapt its practices to be more environmentally sustainable. I believe that this is our responsibility as scientists, but it is also simply necessary to make the field future-proof. Secondly, astronomers can (and should!) use the cosmic perspective on Earth to communicate and educate about the climate crisis. The sense of wonder about our vast Universe and the place of our home within it can unite people and instill a strong incentive to act against the climate crisis.

If you weren’t in the field of astronomy, what would you be doing?
My interests are very wide, so life could have taken me in a lot of different directions! I would love to work with my hands more, making furniture or blowing glass for example, or to take the circus sport I do as a hobby to a professional level. But I suppose I will always have a weak spot for sciences and STEAM fields, and working as a biologist or geologist also sounds terribly interesting. I am happy doing what I do but the world has a lot of amazing things to offer.

Do you have any advice for future astronomers who might also be interested in addressing the climate crisis?
My advice would be to realize that we can all do something and play our part. Whether you simply talk about it with your friends, incorporate climate change into classes for your students, or raise the topic with the governance of your institute, it is all worthwhile. And most importantly, keep focusing on the positive changes we can make, it can be overwhelming to try and create change. And anyone who is looking for advice or support is of course welcome to join A4E and strengthen the movement!

Astronomers for Planet Earth: Gina Maffey

This feature is part of our ongoing series about the amazing women at Astronomers for Planet Earth (A4E), a global network of astronomers and astronomy enthusiasts dedicated to offering their unique perspective to the fight for climate justice. For this post, we'll hear from Dr. Gina Maffey, an interdisciplinary science communicator and founder of the Wildeor Foundation.

And be sure to check out A4E's white paper on what astronomers (like you!) can do to address the climate crisis: Astronomers for Planet Earth: Engaging with the Public to Forge a Sustainable Future.

Dr. Gina Maffey is an experienced science communicator and interdisciplinary scientist with a guiding passion for the natural world. 

What is your current career and how did you end up there?

I currently sit as the chair of the Wildeor Foundation—a charity with the aim of Bringing Nature Back to Life. It’s been a very windy road getting here, but the path has never veered too far from environmental topics. Academically, I started in the UK with a BSc in Zoology, Masters in Ecology and Environmental Sustainability and a PhD in Environmental Science. However, during this time I also built up a portfolio of experience in science communication, including a British Science Association Media Fellowship. I began to wonder whether moving to another discipline would offer an opportunity to really understand and improve my science communication skill set. After working in South America for two years in environmental communication I accepted a part-time post in the Netherlands at the Joint Institute for VLBI ERIC (JIVE)—a European Radio Astronomy Institute—where I was introduced to a whole new universe of concepts, ideas and terminology. Throughout my time at JIVE I maintained a strong connection with the natural world, also working with conservation and outdoor skills organizations - and even spending a year living outside in some of the wonderful natural areas that the Netherlands has to offer. I was inspired by many of the conversations that I had with the astronomy community and a small group of us came together to establish the Wildeor Foundation, where we are keen to explore cross-disciplinary approaches to nature connection in everyday life.

What is your role in Astronomers for Planet Earth (A4E)?
I am one of the co-founders of the European arm of A4E. This began in 2019 at the European Astronomical Society conference in Lyon—what started as a conversation with one astronomer on climate change quickly snowballed into our first official meeting by the end of the week. As we were establishing ourselves we came across the newly formed Astronomers for Planet Earth in the US; at this point, we met online and joined forces to form an international group—after all, there is only one planet we are fighting for! I continue to be actively involved in many different aspects of A4E, and currently this is focused on much of the background framework to ensure the long term sustainability of the movement.

What goals do you have for your role in A4E?
I really want to work towards astronomers having a key voice in the environmental movement. I continue to be inspired by the dedication and depth that astronomers engage with the climate crisis, you (astronomers) speak the language of data and you can see that data as part of a much greater and complex picture. The climate crisis may be our global society’s most pressing problem, but it sits alongside a plethora of environmental issues that require as many voices as possible to collectively shout that something needs to be done, now.

Dr. Maffey observes the delicate beauty of an elephant hawk moth.

Describe the first time you made a personal connection between your passion for astronomy and the urgency of fighting climate change.
For me, this sits the other way round. My passion for environmental issues has never waned, and engaging with the astronomy sector has only stimulated me further. To pin an actual moment in time is difficult, but the greatest catalyst was undoubtedly meeting the wonderful group of people at the 2019 European Astronomical Society in Lyon. Many of these individuals have become friends through the A4E movement and that social interaction in turn serves as an incredible motivator.

How does your career in astronomy intersect with the fight against climate change?
It has steered my career in ways that I could never have anticipated. I have been lucky enough to present and write about astronomy and climate change, which forces me to review and reflect on my own thinking and I am continually challenged by the discussions that occur through A4E. Above all though, it is influencing how the Wildeor Foundation is growing. It is now less an intersection and more a parallel, conjoined path.

How can the astronomical community engage with the climate crisis movement?
By understanding how environmental change will affect the conduct of astronomy. It is somewhat misleading to think of environmental topics under a disciplinary label. The environment should form the foundation of each action and decision that we take— what will the long term impact be? What is the true economic cost? Who will be affected by the decisions that we make now? Asking these kinds of questions embeds astronomy in both (local and global) social and environmental frameworks. It also demonstrates that there is a lot of room for change, and that, at the very least, astronomers have the power to make those changes in their own field.

If you weren’t in the field of astronomy, what would you be doing?
Investment banking.

No, I jest. I still think of myself as an outsider in astronomy, just as I do in ecology, environmental science and science communication. For me, the labels mean little, but my interest for nature runs deep. I know that wherever I was, even in investment banking, I would be fighting on behalf of the natural world.

Do you have any advice for future astronomers who might also be interested in addressing the climate crisis?
Join Astronomers for Planet Earth.
Start asking questions and challenge the status quo.
Finally, don’t be intimidated, there is an overwhelming amount of data on climate change, there are climate scientists, climate communicators, climate policy officers… the list goes on. It is impossible to read and know everything, the unifying factor is that those in the field trust what the data is telling them and understand that change has to happen now. The best thing you can do is support them and amplify their message.
