We are delighted to announce that Sadie Coffin, PhD student and co-lead (alongside her advisor, Dr. Jeyhan Kartaltepe) of the Redshift Wrangler project, will serve as the AAPS-NASA Cit Sci Leaders Fellow. Sadie’s task is to curate resources, advice, and best practices on topics of common interest from four years of NASA Cit Sci Leaders events. Sadie will dig into our recordings to find the moments, speakers, advice, and resources that offer the best guidance for project leaders starting or managing projects. She’ll help package the best elements of the recordings into usable formats for busy scientists and project leaders interested in creating, managing, and improving participatory science projects.
“This fellowship offers a unique opportunity to gain the mentorship and expertise I need to build a career that not only advances research but also fosters public engagement and inclusivity in science,” said Sadie.
The enthusiasm, talent, and passion in the applications we received revealed the broad appeal, utility, and growing acceptance of participatory research. One applicant commented, “Working in the participatory sciences is how I find meaning in my career as a researcher.” Many others commented that they were eager to connect with mentors and colleagues who were as invested in this work as they were.
Thank you to everyone who applied for this fellowship and to all of the early career professionals working in this field. You are inspiring, and we can’t wait to see what big ideas you contribute to the growth of this field! AAPS will announce additional fellowships focused on different projects in the coming months.

In October 1604, a new star appeared in the sky, puzzling astronomers of the day. First observed on Oct. 9, German astronomer Johannes Kepler (1571-1630) began his observations on Oct. 17 and tracked the new star for over a year. During that time, it brightened to magnitude -2.5, outshining Jupiter, and for several weeks remained visible in the daytime. Publication of his detailed observations in 1606 led astronomers to call the star Kepler’s Supernova, today formally designated as supernova SN 1604. Astronomers of the day did not know what caused the star’s sudden appearance and eventual disappearance, but the phenomenon helped shape European cosmology toward the heliocentric model proposed by Polish astronomer Nicolaus Copernicus half a century earlier. Today, astronomers designate SN 1604 as a Type Ia supernova, resulting from the explosion of a white dwarf star, and use ground-based and space-based telescopes to study its remnants.

Right: Closeup of Kepler’s illustration of the location of the new star, designated N, in the constellation Ophiuchus near the right foot of the serpent-bearer.
Italian astronomer Lodovico delle Colombo first observed the supernova in the constellation Ophiuchus on Oct. 9. Kepler, then working in Prague, heard rumors of the new star but did not observe it until Oct. 17. He continued to monitor the star for over a year, inspired by the earlier work of Danish astronomer Tycho Brahe’s observations of a similar phenomenon, the 1572 supernova. The new star quickly brightened to magnitude -2.5, outshining Jupiter, and for three weeks could be seen in the daytime before finally fading into obscurity in March 1606. Kepler could only make naked eye observations, since Italian astronomer Galileo Galilei didn’t turn his newly invented telescope to the skies for another four years after SN 1604 faded from view.
Later in 1606, Kepler summarized his observations in his book De Stella nova in pede Serpentarii (On the New Star in Ophiuchus’ Foot), published in Prague. SN 1604 is believed to be about 20,000 light years away, near the edge of a dark nebula complex. Kepler and his contemporaries observed not only the last known supernova to occur in the Milky Way Galaxy but also the last supernova visible to the naked eye until 1987. That one, Supernova 1987A, appeared in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way.
A Type Ia supernova results from a white dwarf drawing in material from a nearby red giant star, the additional mass leading to a runaway thermonuclear explosion.
Astronomers today understand that what Kepler and others believed as the birth of a new star actually represented the violent death of a star. Astronomers today classify supernovas according to their characteristics, and SN 1604 belongs to the group known as Type Ia supernovas, typically found in binary star systems composed of a white dwarf and a red giant. The gravitation force of the white dwarf draws in material from its larger less dense companion until it reaches a critical mass, around 1.4 times the mass of our Sun. At that point, a runaway thermonuclear chain reaction begins, causing a release of tremendous amounts of energy, including light, that we see as a sudden brightening of an otherwise dim star.

Supernova explosions leave remnants behind and those of SN 1604 remain visible today. Ground-based and space-based instruments using different parts of the electromagnetic spectrum study these remnants to gain a better understanding of their origins. The remnants of SN 1604 emit energy most strongly in the radio and X-ray parts of the electromagnetic spectrum. In recent years, astronomers have used Type Ia supernovas to determine the rate of expansion of the universe. Because Type Ia supernovas all occur in stars of about 1.4 solar masses, they give out about the same amount of light. This makes them useful as distance indicators – if one Type Ia supernova is dimmer than another one, it is further away by an amount that astronomers can calculate. Based on this information, astronomers believe that the expansion of the universe is accelerating, possibly caused by the presence of a mysterious substance called dark energy.

Although surrounded by the big and bold missions of human spaceflight, Margaret Kennedy, an aerospace systems engineer on the Human Health and Performance Contract, still appreciates the little things. Ask about her favorite NASA experience to date and she will tell you it is getting to show her badge to the gate guards at Houston’s Johnson Space Center every day. “Knowing I get to be a part of things that can change the world – that I’m helping to make it possible for astronauts to do their job safely, which in turn supports life on Earth – is very rewarding,” she said.
Margaret Kennedy poses with Johnson Space Center’s inflatable mascot, Cosmo, at Comicpalooza 2024 in Houston, Texas. Image courtesy of Margaret Kennedy Kennedy joined the Johnson team as a contractor with Aegis Aerospace in October 2019. Since then, she has spent most of her time as a systems engineer for the Human Research Program’s Program Integration and Strategic Planning group. That role required her to collect technical information for various projects and to ensure systems were in place to correctly track and manage program documents and agreements. This spring, Kennedy transitioned to a new role in which she provides systems engineering for flight hardware supporting Gateway and exploration missions to the Moon and Mars.
She started engaging with Johnson’s Employee Resource Groups (ERGs) shortly before the COVID-19 pandemic and jumped at the chance to get more involved once employees came back onsite. “A few people have been surprised when I tell them I’m really an introvert, not an extrovert, but I had to get out of my shell or I’d still be stuck in my apartment,” she said. “The ERGs were a way for me get out of my space and have allowed me to grow.”
Kennedy is thankful the Johnson Parenting ERG started allowing contractors to serve as secretaries because that led to similar opportunities with other ERGs. She served as the membership secretary for both Emerge and Out & Allied ERG (OAERG) in 2023 and is currently OAERG’s executive secretary. “I help keep our chair and co-chair up to date,” she said. “I have my finger on everything that’s happening in the ERG.” Filling these roles gives Kennedy numerous opportunities to support diversity, equity, and inclusion at Johnson, the most recent of which was her participation on a panel during the center’s Diversity, Equity, Inclusion, and Accessibility Day.

Even if you only get a hair’s width outside your zone of comfort, it makes a difference.”
She also said that simply participating in ERG meetings and events – whether in person or virtually – is another great way to get involved. “The ERGs can’t do what we do without you,” she said. “We do it because it’s important to us and to others, but we sometimes struggle to know what people want. We need your thoughts and your ideas because it helps us provide programming and inform the center about what is happening.”
Being a part of OAERG in particular has helped Kennedy personally and professionally. “It has provided me with a space to be my authentic self and bring that person to both the world and work,” she said. “In the long line of LGBTQI+ letter soup, I end up in the + on the end more times than not. Out & Allied has given me a way to not only embrace my identity but also help spread awareness about it.” Professionally, the ERG has helped her network with a range of people, including upper and middle management, and strengthen her communication, problem solving, and leadership skills.

Image courtesy of Margaret Kennedy Kennedy acknowledged that change can take time, noting that while Johnson’s safety-oriented culture is a strength, it can sometimes slow the pace of initiatives that may not be considered mission critical, as can staffing shortages in some areas. “Things like accessible walkways and gender-neutral bathrooms are still important,” she said, adding that leadership is working on it.
Kennedy encourages everyone at Johnson to check in with their teammates and have “water cooler moments” with their colleagues as a way of promoting inclusivity. “Be patient and willing to give everyone some grace,” she said. “We can get so focused on the mission and what we need that we sometimes forget there are things happening in other people’s lives that can affect their work.”

Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says collaborating with her teams is one of the best parts of her job.UC Santa Cruz, UC Regents Science is often portrayed as a solitary affair, where discoveries are made by lone geniuses toiling in isolation. But Dr. Natasha Batalha, an astronomer at NASA’s Ames Research Center in California’s Silicon Valley, says solving problems with the people around her is one of the best parts of her job.
“Oh, man, working with people is all I do!” said Batalha, whose current research involves using NASA’s James Webb Space Telescope to study exoplanets, planets outside our solar system that orbit other stars.
Batalha’s work explores hot, Jupiter-like exoplanets; smaller, rocky exoplanets more similar to Earth; and brown dwarfs, mysterious objects smaller than a star but huge compared to the biggest planets. A single question has driven her since she was a kid: “Does life exist beyond Earth?”
It’s a lofty question, bigger than any one scientist. And that’s the point.
“I love being part of a larger community,” she said, “We’re working together to try to solve this question that people have been asking for centuries.”
However, the particular joy of belonging wasn’t always present in Batalha’s life.
When she was 10, her family moved from Brazil to the U.S., where she was met with culture shock, pressure to assimilate, and a language barrier. She thinks the latter is partly why she gravitated toward the universal language of math.
Eventually, her interests and strengths took shape around astronomy. When she chose to study physics in college, followed by a dual PhD in astronomy and astrobiology, her parents – who are also scientists – helped fill in for the community she was otherwise lacking.
“In high school, I watched female students drop out of my physics classes,” Batalha said. “The honors physics track in college was devoid of women and people of color. I didn’t feel I had a community in my college classes.”
Her mother, Natalie Batalha, is an astronomer who served as project scientist for NASA’s Kepler space telescope– the mission that taught us there are more planets than stars. Natasha’s father is a LatinX physicist. Both her parents had already faced similar challenges in their careers, and having their example to look at of people who had successfully overcome those barriers helped her push on.
“I identify as female and LatinX, which are both underrepresented groups in STEM,” she said, “but I also have a ton of privilege because my parents are in the field. That gave me a dual perspective on how powerful community is.”
I love being part of a larger community. We’re working together to try to solve this question that people have been asking for centuries.

Since then, empowering her own science community has been a focus of Batalha’s work.
She builds open-source tools, like computer programs for interpreting data, that are available to all. They help scientists use Webb’s exoplanet data to study what climates they may have, the behavior of clouds in their atmospheres, and the chemistry at work there.
“I saw how limiting closed toolsets could be for the community, when only an ‘inner circle’ had access to them,” Batalha said. “So, I wanted to create new tools that would put everyone on the same footing.”
Batalha herself recently used Webb to explore the skies of exoplanet WASP-39 b, a hot gas giant orbiting a star 700 light-years away. She is part of the team that found carbon dioxide and sulfur dioxide there, marking the first time either was detected in an exoplanet atmosphere. Now, she is turning to the difficult-to-discern characteristics of smaller, cooler planets.
Dr. Natasha Batalha has been hooked on the search for life beyond Earth since elementary school.UC Santa Cruz, UC Regents Batalha says she’s exactly where her 6th-grade self imagined she would be. In elementary school, she read a biography of NASA astronaut Sally Ride and was hooked by an idea it contained: that in 20 years the kids reading those words could be the ones pioneering the search for life on Mars.
Today’s youth belong to the Artemis Generation, who will explore farther than people have ever gone before. The Artemis program will send the first woman and first person of color to the lunar surface. Missions over time will build a presence at the Moon to unlock a new era of science and prepare for human missions to Mars and beyond. Along the way, scientists will continue to search for signs of life beyond Earth, an endeavor building on the work of many generations and relying on those in the future to carry on the search.
“That’s something really rewarding about my work at NASA,” she said. “These questions have been asked throughout human history and, by joining the effort to answer them, you’re taking the baton for a while, before passing it on to someone else.”
