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

Happy birthday to #astronomer Henrietta Swan Leavitt (1868-1921) who set the scale of our Universe. My portrait of Leavitt is printed in silvery lavender ink on Japanese kozo paper. Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco, Ursa Minor & Andromeda). ⁠🧵1/ ⁠ #linocut #printmaking #WomenInSTEM #sciart #histsci #astronomy #mastoArt

Day 11 #ArtAdventCalendar: Happy birthday to trailblazing US #astronomer Annie Jump Cannon (1863 – 1941), here with her stellar classification system which sorted stars based on spectral types, revealing their temperature from hot blue to cool red stars: O,B,A, F, G, K & M. Named the Harvard Classification after the university, her tremendous contribution was less visible. 🧵 #printmaking #womenInSTEM #histsci #DisabledInSTEM #linocut #mastoArt
