Timeline of American astronomer Vera Rubin, whose pioneering observations of spiral galaxy rotation curves provided the first direct evidence for dark matter, revolutionizing cosmology.
Vera Florence Cooper is born in Philadelphia, Pennsylvania. Her father, Philip Cooper, an electrical engineer, and her mother, Rose Applebaum, encouraged her early interest in astronomy. #astronomy #biography
Rubin graduates with a bachelor's degree in astronomy from Vassar College, where she was the only astronomy major in her class. She later notes that Vassar had a strong astronomy program for women. #education #astronomy
Vera marries Robert Rubin, a mathematician and physicist. The couple will have four children, all of whom pursue science, including their son Karl Rubin, a mathematician. #personal #science
Rubin earns a master's degree in astronomy from Cornell University, where she studied under William A. Baum and George B. Field. Her thesis investigated the kinematics of spiral galaxies. #education #astronomy
Rubin earns her PhD in astronomy from Georgetown University under the supervision of George Gamow. Her dissertation analyzed the distribution of galaxies in the nearby Universe. #education #astronomy
After her PhD, Rubin teaches at Montgomery College in Maryland for two years. She faces gender discrimination and is denied a full-time position at the Carnegie Institution initially. #career #astronomy
Rubin joins the Carnegie Institution of Washington's Department of Terrestrial Magnetism (DTM), where she would work for the rest of her career. She begins her research on galaxy rotation. #career #astronomy
Rubin gives birth to her first child, David Rubin. She balances family life with her research, often bringing her children to the observatory. #family #science
Rubin publishes a paper on the clustering of galaxies, challenging the notion of a uniform distribution. This work supports the existence of large-scale structure in the universe. #cosmology #astronomy
Rubin's second child, Karl Rubin, is born. Karl will later become a prominent mathematician. #family #science
Rubin starts a long-term collaboration with instrument builder Kent Ford, using the spectrograph Ford designed. This partnership leads to the key observations of galaxy rotation. #collaboration #astronomy
Rubin and Ford use the 72-inch telescope at Lowell Observatory to obtain spectra of Andromeda and other spiral galaxies. They discover that rotation curves remain flat beyond the visible disk. #observations #darkmatter
Rubin and Ford publish their seminal paper on the rotation of the Andromeda galaxy, showing that the rotation curve does not follow Keplerian decline. This is one of the first clear indications of dark matter. #publication #astronomy
Rubin's third child, Judith Rubin, is born. She later becomes a geologist. #family #science
Rubin's fourth child, Andrew Rubin, is born. He later becomes a physicist. #family #science
Rubin and Ford publish a study of 10 spiral galaxies, all showing flat rotation curves. This provides strong evidence for a large amount of unseen mass. #darkmatter #astronomy
