For #spacetober_challenge day 29 prompt orbit: #mathematician and #astronomer Johannes Kepler (1571-1630)! We remember him for his role in the Scientific Revolution, and his three laws of planetary motion in particular. His laws modified Copernicus’ heliocentric model; he replaced the circular orbits with elliptical ones & described velocities of planets. Today we know them as:

Happy birthday to #mathematician & geodesist Gladys West (née Brown 1930)! Shown with 3 satellites important to her career + tracks: Seasat, GEOS-3 & a GPS satellite. Her work, using math to precisely model the shape of Earth, laid the groundwork for GPS! Born to sharecropper parents in Virginia, she graduated with a Math BSc in ‘52 then MSc at VSU in ‘55. She started her career at 🧵

For the #Spacetober_challenge day 23 prompt space station I made a tiny linocut print of the track of the ISS across the night sky.

For Day 21 of @spacetober_challenge #spacetober_challenge prompt star: 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. 🧵1/

For #spacetober_challenge prompt telescope: #astrophysicist Jocelyn Bell Burnell as a grad student in ‘67 discovered the 1st radio pulsar, a highly magnetized, rotating neutron star that emits a beam of EM radiation. This radiation can only be observed when the star is pointed towards us; so, like the light from a lighthouse, it appears to pulse at a precise frequency. She had been working with her supervisor Hewish & others to construct a radio telescope 🧵1/

For the #Spacetober_challenge prompt historic person, day 17, I’m sharing my portrait of British-born, American #astrophysicist Margaret Burbidge (1919-2020) who was one of the people instrumental in building our understanding of stellar nucleosynthesis, how nuclei are produced in stars & that you and I are all stardust! She was the 1st author of a monumental scientific paper Synthesis of the Elements in Stars, 🧵

New print for #Spacetober_challenge prompt day 16: parachute! 🪂

This is a collaged lino block print with an image of the parachute deployed during the descent of the Mars Perseverance rover as it landed on the planet February 18, 2021. The spacecraft team selected the red and white stripes to encode a secret message in binary: "DARE MIGHTY THINGS" along with

For #spacetober_challenge day 15 prompt blackhole: my 6” x 8” mono print, built up with layers of ink on a gel plate of a Super Massive Blackholes (SMBH) with relativistic jets.

The #Spacetober_challenge @spacetober_challenge day 4 prompt is moon so I’m sharing my Theia #linocut about the formation of our moon. This 6 colour hand printed linocut print illustrates the formation of the Moon in a comic book influenced pop art style. The favoured model of Moon formation is that 4.5 billion years ago, early in the history of our solar system, a Mars-sized astronomical body called Theia crashed 🧵
