Ochoa says, "After a day of running between the House and the Senate, I left with a sense that I had done something to protect the funding for my research, but that the work is far from over. While this year's CVD primarily focused on advocating for science funding, there are numerous other issues important to US astronomers, such as dark skies and space debris, that also require advocates."

Read the rest of Ochoa's experience as an advocate in The Unknowns of Science (Policy).

Congressional Visits Day for 2026 are April 13-15, and applications are open through February 1.

How Women’s Invisible Labor Shaped Astronomy

By Kimberly Mitchell

For centuries, the work women did in astronomy went uncredited. Much of that work has been lost to the past, but some examples exist of women astronomers whose work was never fully recognized in their time or was attributed to men. 

  • Sophia Brahe (1556–1643) assisted her brother, Tycho Brahe, with detailed astronomical observations and record‑keeping that Tycho used in his publication, “De Nova Stella.” Her contributions were treated as assistant work, although the observations she helped produce were foundational for heliocentric orbital theory.

  • Maria Margarethe Winckelmann Kirch (1670–1720) collaborated closely with her husband, Gottfried Kirch, at the Berlin Academy, making observations and calculations and co‑discovering at least one comet in 1702. The comet discovery was formally credited to her husband, and after his death, Maria was denied his post because of her gender.

  • Caroline Herschel (1750–1848) catalogued nebulae and clusters, discovered multiple comets, and compiled an influential index of nebulae that underpinned her brother, William Herschel’s, work. Much of her cataloging and reduction work appeared under William’s name, with Caroline described as an assistant, despite being the first salaried woman astronomer and an accomplished observer in her own right.

We will never fully know the extent to which women contributed to astronomy in its earliest recorded days, but these women, whose efforts went mostly unrecognized or whose contributions were downplayed, were part of the early invisible labor that shaped astronomy.


Moving from the early modern era to the late modern era, women’s contributions to astronomy continued, with work still largely invisible or unacknowledged. In the 19th and 20th centuries, women filled the roles of human “computers.” The calculations they made pushed astronomy forward even as their contributions remained largely unknown. 

  • Annie Maunder (1868–1947) was one of the first “lady computers” at the Royal Observatory, Greenwich. Maunder worked alongside her husband, Edward, studying the prolonged period of time from 1645 to 1715 when little sunspot activity appeared on the Sun. Edward Maunder eventually published two papers on the phenomenon, but Annie’s name was excluded because she lacked a college degree. This work is now known as the Maunder Minimum, with Annie finally getting the credit she deserves.

  • Mary Adela Blagg (1858–1944) was a self‑taught mathematician who did meticulous work standardizing lunar nomenclature and analyzing lunar features. Her observations were crucial to lunar mapping. She also worked on variable stars. 

  • Women worked as “computers” at many major observatories (Harvard, Yerkes, Mount Wilson, etc.) They measured positions, spectra, and brightnesses from photographic plates to produce catalogs of stellar classification, variable‑star studies, and galactic structure. Their contributions are buried in annual reports and plate logs, remaining largely unknown.

  • Jocelyn Bell Burnell (b. 1943) identified the first radio pulsar in the data from a new radio telescope she helped build while still a graduate student. The 1974 Nobel Prize for this discovery went to her (male) supervisor and a senior colleague, with Bell Burnell’s contribution omitted completely. As Bell Burnell was graduate student, the omission was controversial, but her contribution to the discovery was well-documented.

  • Margaret Burbidge (1919–2020) co‑authored the landmark B²FH paper explaining how elements are formed in stars and was a leader in observational spectroscopy. While she is now well-known, she faced early exclusion from the use of some telescopes.

While women in astronomy today are now credited for their work, the invisible labor continues in various ways, ultimately affecting individual careers and the advancement of women in the field in the long run. 

Invisible labor continues to impact the lives and work of women astronomers. While it looks different today than simply excluding women from recognition for their work, it is still a significant problem that must be recognized and rectified to bring true parity to the field.

Crosspost: Picture an Astronomer: Best Practices for Retaining Talent in Astrophysics

Our crosspost today is from a newly released whitepaper edited by Ava Polzin and Katherine E. Whitaker about the challenges women in astronomy face and how these might be overcome.

The background is one of the first light images from the NSF-DOE Vera C. Rubin Observatory released June 2025. It is the first major observatory to be named after a woman. All art by Julie Malewicz.

Summary:


Women are consistently underrepresented in astrophysics yet are simultaneously subject to disproportionate attrition at every career stage. This disparity between demonstrated efficacy in job performance and ultimate career outcome was the primary motivation for the Picture an Astronomer series, which included both targeted public outreach to increase representation of women in astrophysics and high-level, solution-oriented discussions among professional astronomers. 

In March 2025, more than 200 astronomers came together in a hybrid-format symposium focused on the state of the field for female scientists, combining scientific exchange with discussions of policies and practices to strengthen retention of talent in the field. This white paper is the result of those discussions, offering a wide range of recommendations developed in the context of gendered attrition in astrophysics but which ultimately support a healthier climate for all scientists alike.

Excerpt from the foreword by C. Megan Urry:


One particular conversation when I was a postdoc in the 1980s clarified both the ubiquity and inaccuracy of the upside-down notion that women had it easier than men. It started with the usual statement from a male colleague that, thanks to affirmative action, I would have no difficulty advancing in the field (a claim wildly contrary to the lack of encouragement I experienced to that point). I challenged him to substantiate that view. He launched into a story about a woman hired as faculty at a top university despite her complete lack of qualifications, and despite overwhelming competition from an outstanding young man for whom the job had actually been intended. But an interfering Dean had insisted that this woman be added to the short list and then insisted that she be hired. I might have believed this story—after all, such stories were commonplace—but when I asked who the woman was and what her research area was, the storyteller didn’t know any details. 

Wait, I said, you don’t know who she is or what she does but you are sure she was unqualified? “Everyone knows this is true,” he responded

As scientists, we know this isn’t how evidence and scientific analysis is supposed to work. Before coming to conclusions, we seek facts and are skeptical of broad claims— you don’t just accept some story because it aligns with your beliefs. Later, I happened to meet someone who had been on the actual search committee for that position. When I recounted the story to him, he—a person who was there, who participated in the deliberations and the decision to hire this woman—told me the story was flat out wrong. 

In fact, the woman had been on the short list from the get-go and was hired because she was the strongest candidate by far. According to this first-hand account, she blew the rest of them out of the water, including the young man who was a supposed shoo-in. This jolted me into a new awareness of the realities of my profession. I began to see that women2 were judged differently than men—indeed, much more harshly—which the social science literature confirms. We were less likely to be seen as academic stars, more likely to be criticized or overlooked. At the Space Telescope Science Institute (STScI), created in 1981, the tenure-track staff included only one woman (Neta Bahcall) among the first 60 people hired. This was despite the fact that women received 10-20% of the PhDs in astronomy in the 1980s. I was the third woman hired onto the tenure track, after Anne Kinney. 

She and I started asking, “Why so few?”
