016-sunjammer-dixon – The pressure of sunlight on a solar sail carries tourists to the Earth from the moon, seen reflected in the sail. A technical concept painting depicting a massive, circular solar sail spacecraft navigating interplanetary space. The primary craft features a vast, lightweight reflecting sail structured with radial and concentric rigging, centered on a gold cylindrical payload module. Another, distant sailship is visible in the lower left quadrant against the black starfield. The crescent limb of the Moon is reflected in the sail along with the glaring sun, whose light pushes the craft. A full Earth is visible through a central hole in the sail. Oil on canvas panel, 24x36 inches, 1972.

Cyclotron
418-cyclotron-diagram-dixon – In a cyclotron, or toroidal particle collider, such as the LHC in Geneva, streams of protons are accelerated in oppoisite directions by magnetic fields and then are deflected to collide head-on. A technical three-dimensional diagram illustrating subatomic particle acceleration within a circular ring accelerator or synchrotron. The cutaway view reveals two counter-rotating particle beams, represented by illuminated orange and blue trajectories, traveling through a toroidal vacuum chamber wrapped in electromagnetic focusing coils. The beams converge at a designated collision point surrounded by an array labeled "DETECTORS," where a high-energy particle impact event is visualized.The resulting burst of sub-atomic particles tells us much about the nature of the universe. Digital, for Scientific American, 2005.

206-shuttle-and-comet-dixon – Shuttle And Comet - Spacelab mission during apparition of Halley's Comet (mission never flown). A stunning space illustration depicting a Space Shuttle orbiter carrying an ESA Spacelab module in its payload bay, maneuvers in Earth orbit. The spacecraft flies along a glowing orange and yellow atmospheric horizon line that splits the blue planet from deep space. In the dark starfield background, there is a brilliant comet with a prominent ice-blue plasma and dust tail, creating a striking cosmic juxtaposition. acrylic and gouache, 1985. digitally remastered, 2026
560-space-colony-cover-dixon - The interior landscape of a massive, rotating cylindrical space colony arches upward into the background, showcasing a curved overhead sky dominated by the linear streaks of a starlight window and a central structural column. Lush green, terraced hillsides on the left feature modern, stilt-supported residential modules, while a woman in a red gown tends to hanging plants on a balcony in the immediate foreground. In the distant center and right, an organized urban layout with modular architecture extends along the cylinder’s interior curve beneath a bright, reflected solar source. cover painting for Colonies in Space by T.A. Heppenheimer, 1977, acrylic and gouache on board.
