Pioneering Mexican Astronomer Julieta Fierro Dies at 77
Mexico City – Julieta Fierro,a leading Mexican astronomer and passionate advocate for science communication,has died at the age of 77. Fierro, renowned for making complex astronomical concepts accessible to the public, passed away leaving behind a legacy of groundbreaking research and a commitment to social justice.
Fierro dedicated her life to unraveling the mysteries of the universe, specializing in planetary nebulae and the chemical evolution of the universe. She earned her doctorate in astrophysics from the University of California, Berkeley, and became a prominent figure at the Institute of Astronomy of the National Autonomous University of Mexico (UNAM).
Beyond her scientific contributions, Fierro was a vocal public intellectual, unafraid to tackle controversial issues. She openly supported legislation aimed at preventing young mothers from abandoning their studies, advocated for a law permitting euthanasia for a “decent death,” championed the installation of solar panels in Mexico’s deserts, and even called for drug legalization.
In a recent public appearance at the Hay Festival Querรฉtaro in early September, when asked about the purpose of astronomy, Fierro reflected that the discipline served to help her “find herself and to ‘return to the origins of humanity, things and nature.'”
fierro’s dedication to sharing her knowledge is evident in her extensive bibliography, which includes: Astronomy, for what (Sexto Piso), explaining the practical applications of astronomy; Astronomy challenges (Mexican Academy of Language), geared towards young readers; The chemical evolution of the universe (Economic Culture Fund), co-authored with Manuel Peimbert; Planetary nebulae (Economic Culture Fund), co-authored with Silvia Torres; Galileo and El Telescope, 400 years of science; Astral letters: a scientific romance of the third type, co-authored with Adolfo Sรกnchez Valenzuela; and the surprisingly popular THE BOOK OF LAS CICHINADAS, co-authored with Juan Tonda, which has sold over 100,000 copies in Mexico with its humorous take on bodily functions.
Fierro’s passing marks a meaningful loss for the Mexican scientific community and for all those who benefited from her tireless efforts to bring the wonders of the cosmos to a wider audience.She will be remembered not only as a brilliant astronomer but as a champion of accessible science and a fearless voice for progressive change.
