joerojasburke:An X-ray image of the Cassiopeia-A supernova rendered in needlepoint by astronomer and astrophysicist Cecilia Payne-Gaposchkin. (She was the first to work out that stars are predominantly made of hydrogen, a pivotal finding at odds with expert opinion in the 1920s, when she published the work in a doctoral dissertation.)She crafted the needlepoint in 1975. It being the 70s, her friend and colleague John R. Whitman had to use a giant mainframe computer at the Smithsonian Institution’s Center for Short-Lived Phenomena to output the schematic.via True Anomolies -- source link
