Vera Rubin

Biography

Vera Rubin transformed dark matter from a curiosity into a central problem of physics. Measuring how stars orbit within spiral galaxies, she found that the outer regions move just as fast as the inner ones — impossible unless the galaxies are embedded in vast halos of unseen mass. The Vera C. Rubin Observatory is named in her honour.
