Artist Caitlin Russell's "The Outer Sun" series pairs her carefully composed works with descriptions of theories of the universe, present and past, believable and absurd. For the above image, the caption reads: "fig. 7 ~ The planets travel on elliptical orbits around the sun. (Johannes Kepler, Astronomia nova, 1609)"

You can see the rest of this series illustrations at The Outer Sun, buy prints of Russell's work at her store, and see more work at her website.
