As described, my linocut is a space travel poster for a future where we all share the citizenship of Earth and can take rapid transport to Europa, one of Jupiter's moons, known as the Galilean Moons (named after Galileo, who first observed them with a telescope. There’s a view of a section of Jupiter with big red spot and its moon Europa. Text reads “Take the Europa Express, your passport to the Galilean Moons.” There’s a hand holding a blue passport with a ticket in it. The passport has a stylized image of Earth with the symbol for Earth and the words “Earth Passport” on it. Each print is burnished by hand onto lovely Japanese kozo (or mulberry) paper in a creamy ivory colour, 8" x 10" (or 20.3 cm by 25.4 cm).

My linocut portrait of astronomer Vera Rubin with short hair, glasses and resting her face in her hand in burgundy on a background of outer space with stars and galaxies in black with blue and pink splotches to mimic how dust bends light in space. At the base of the print is a large spiral galaxy with a plot of orbital velocity versus distance going out from its centre (so the distance axis is indeed distance from centre). There are two lines labelled “observed” which goes up from the origin and then is a pretty flat wavy line all the way across. This line marks the bottom of Rubin. Below it is a wide empty gap of visible white paper down to the second line labelled “predicted”. The Predicted line goes up from the origin to a peak where it diverges from the observed and falls smoothly back down in a gentle curve.

My linocut portrait of Johannes Kepler on cream coloured washi paper. Kepler is in Renaissance garb printed in indigo. He holds a compass and rests his hand on his model of nested Platonic solids from Mysterium Cosmographicum, printed in gold ink. Above that in silver in are 7 musical staves with notes next to symbols for related planetary bodies: Mercury, Venus, Earth and Moon, Mars, Jupiter and Saturn. Over his other shoulder are 3 schematic diagrams drawn in ellipses (oriented with the semi-major axes horizontal) in magenta. The top one relates to his first law and shows an ellipse cut in two horizontally, the two foci labelled F and F’ and a triangle drawn to a point P on the ellipse (FPF’). The middle ellipse (2nd law) shows the Sun at a focus, and a series of circles on the ellipse as a planet such that the sections are equal area and alternate colouring (magenta or none) like a peppermint. The bottom ellipse (3rd law) is cut in half with semi-major and semi-minor axes shown

My linocut of Annie Jump Cannon shows her in a 3/4 profile view wearing a shirt with a lace collar and her hair up. She is printed in a gradient of violet at the bottom to green at the top, printed on white 11” x 14” paper. The background is printed in a gradient (left to right) of dark blue, light blue, yellow, pale yellow, pale orange, orange and red. The background block excludes her silhouette of shoulder and head with the exception of a smattering of small dots in a swath from upper left to lower right (which extends to white spots on the coloured background). Also along the bottom are a series of circles of decreasing size (left to right, blue through red) labelled O, B, A, F, G, K, M. There’s a axis line along the bottom with 6 tick marks.
