Vera Rubin

Vera Rubin (1928–2016) was an American astronomer at the Carnegie Institution who fundamentally advanced our understanding of the universe. Through careful observations of galaxy rotation curves, she provided compelling evidence for dark matter—the invisible matter comprising the vast majority of the cosmos. Her discoveries became foundational to modern cosmology, demonstrating that the visible universe represents only a small fraction of all matter.

Rubin's scientific legacy extends beyond her groundbreaking research. She was a persistent advocate for women in science and a model of intellectual curiosity across her career. Her work continues to guide investigations into dark matter and the large-scale structure of the universe, making her one of the most influential astronomers of the twentieth century.
