She helped prove one of the most important discoveries in modern astronomy.
She was never awarded a Nobel Prize for it.
Born in 1928, Vera Rubin pursued astronomy at a time when women faced major barriers in the field. Princeton rejected her graduate application because she was a woman.
Rubin kept going.
In 1965, she became the first woman officially permitted to observe at Palomar Observatory. The observatory had barred women in part because it had no women’s restroom. When Rubin arrived, she drew a skirt on a paper figure and taped it to the men’s restroom door.
Then she found something that changed our understanding of the universe.
By studying the rotation of galaxies, Rubin found evidence that vast amounts of invisible matter were holding them together. Her work became some of the strongest evidence for what we now call dark matter.
She never received a Nobel Prize. She died in 2016.
Three years later, the National Science Foundation renamed a major observatory in her honor. The Vera C. Rubin Observatory became the first U.S. national observatory named after a woman.
