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
