Today, we come together to honor and celebrate the incredible contributions of women astronomers who have played a vital role in exploring the mysteries of the universe. Their brilliance, dedication, and perseverance have paved the way for future generations of aspiring stargazers and scientists. Throughout history, women astronomers have defied societal norms and overcome numerous obstacles to pursue their passions. Their thirst for knowledge and unwavering curiosity have driven groundbreaking discoveries that have enriched our understanding of the cosmos.
Spectroscopy has been crucial in identifying and characterizing distant exoplanets. By analyzing the light passing through an exoplanet’s atmosphere, astronomers can infer the presence of specific gasses and potential signs of habitability. The study of the spectra of galaxies has also provided important insights into the expansion of the universe, dark matter, and dark energy.
Caroline Herschel
Caroline Herschel became the first woman to be credited with the discovery of a comet, known as “C/1786 P1.” Over the years, Caroline continued her astronomical work, discovering several more comets and recording her observations meticulously. In 1828, she was awarded the Gold Medal of the Royal Astronomical Society for her significant contributions to astronomy.
Cecilia Payne-Gaposchkin
Women astronomers have played a significant role in advancing spectroscopy techniques and using them to make groundbreaking discoveries. For example, spectroscopy has been instrumental in identifying the elemental composition of stars, enabling scientists like Cecilia Payne-Gaposchkin to demonstrate that hydrogen is the primary component of stars, a revolutionary idea in the 1920’s.
Vera Rubin
By using spectroscopy, Vera Rubin was able to measure the velocities of stars within galaxies and observe how their velocities change with distance from the galactic center. Her observations revealed that the outer regions of galaxies were rotating much faster than they should have been based on the visible mass alone. This discrepancy in the rotation curves provided evidence for the existence of dark matter, as there must be additional unseen mass contributing to the observed velocities.
