Happy birthday to #astronomer Vera Rubin (neé Cooper, ‘28-‘16) & her discovery that angular motion of galaxies deviates from predictions, 1st evidence for dark matter, now known as 5x as common as matter & the stuff which dictates dynamics of galaxies & evolution of our universe! The Nobel committee waited 3 years after she died to reward another for the theory of dark matter. 🧵1/ https://minouette.etsy.com/listing/1393796836 #printmaking #sciart #linocut #mastoArt
