A massive, multi-ringed orbital space station with a long central tower axis floats in deep space, suffering a bright orange and yellow explosion on its outermost ring. Below the damaged complex, a small crescent planet hangs suspended against a chaotic background dominated by an expansive, fiery spiral galaxy. The galactic core burns with intense orange, gold, and white light, while turbulent dust lanes and brilliant blue star-forming clusters swirl through the outer spiral arms.

			<image:title>Green Mars Cover Painting</image:title>
			<image:caption>289-green-mars-dixon – cover painting for book two of the science fiction trilogy by Kim Stanley Robinson. I began the painting in 1993 sitting outside Biosphere II in Arizona with “Bionauts” watching through the glass. There are hints of the Biosphere architecture in the painting. A vast Martian canyon landscape undergoes terraforming, featuring a winding river reflecting a distant, low-slung sun or atmospheric laser line, with alpine pine trees taking root along the rugged rocky cliffs and cold foreground slopes. A central vertical montage strip divides the composition, displaying six distinct science fiction scenes from top to bottom: a complex orbital space station, a high-altitude research glider soaring above an orange Martian atmosphere, an erupting volcano venting gases, an industrial terraforming plant with a cooling tower near biodomes, a heavy mechanical walking harvester or crane chassis, and a spacesuited explorer surveying a rugged, pinkish alien hillside. The wide right-hand side reveals an intricate habitat structure built directly into a massive cavern opening within a sheer canyon wall. acrylic on illustration board, overall size 17x21.5 inches, picture area 16x20.5 inches. 1995</image:caption>

			<image:caption>366-evolving-orbits-dixon – This two-part technical diagram illustrates the dynamic evolution of planetary and planetesimal orbits within a stellar system, contrasting an early configuration with a later, rearranged state. The upper panel shows an initial stage where thin, concentric, color-coded rings (orange, green, light blue, and white) encircle a central star on a single, relatively flat plane. The lower panel depicts a post-migration phase where the orbits have destabilized and evolved, showcasing an expanded, highly elongated, and eccentric outer white orbit that stretches far into the foreground, while the inner planetary tracks remain relatively contained. Gravitational perturbations may have caused the orbit of Pluto to become more elliptical. digital, 2004, copyright Don Dixon</image:caption>

			<image:caption>458-cepheid-variable-cycle-dixon – A Cepheid variable star pulses in a regular period that is directly related to its intrinsic brightness, allowing astronomers to use such stars as &quot;standard candles&quot; to measure distances to other galaxies. A three-panel sequential astronomical illustration demonstrating the dramatic pulsation cycle of a Cepheid variable star as observed from the surface of a barren, airless rocky planet or moon. The panels depict a time-lapse sequence tracking the simultaneous changes in the star&apos;s physical size, color temperature, and luminosity, along with the corresponding illumination cast onto the craggy landscape below. Left Panel: The star is at its minimum size but highest temperature, appearing as a compact, intense white-blue sphere that casts sharp, cool, violet-tinted highlights onto the rocky ridges. Middle Panel: The star expands into its largest and coolest state, swelling into a massive golden-yellow supergiant that floods the entire planetary landscape with a warm, amber-orange glow. Right Panel: The star contracts back to its compressed, highly energetic white-blue state, returning the landscape to its initial coolly lit appearance and completing the periodic cycle.Artwork for cientific American, © 2007 Don Dixon / cosmographica.com</image:caption>

			<image:caption>457-type-ia-supernova-mechanism-dixon – Diagram for Scientific American shows second type of supernova. A vertical, multi-stage astrophysical infographic illustrating the sequential mechanics of a Type Ia supernova explosion within a binary star system. The process flows downward against a black space background, detailing the progression from mass transfer to runaway thermonuclear detonation. Top Stage: A massive yellow donor star undergoes Roche lobe overflow, stripping its outer envelope into an accretion disk surrounding a compact, white dwarf companion star. Second Stage: A detailed callout focuses on the white dwarf, showing a cutaway of its internal shell structure as it approaches the Chandrasekhar limit (approximately 1.44 solar masses). A secondary callout zooms in further on the carbon-oxygen core where turbulent, runaway nuclear fusion is triggered.Third Stage: The white dwarf is shown in partial cross-section as a supersonic deflagration/detonation wave rips outward from the core, shattering the star&apos;s crystalline electron-degenerate structure amid brilliant rays of energy. Bottom Stage: The sequence culminates in a catastrophic thermonuclear explosion, showing a blinding white-hot central core surrounded by a rapidly expanding, turbulent orange shockwave shell that completely obliterates the white dwarf.

			<image:caption>454-type-2-supernova-diagram-dixon – Diagram for Scientific American shows steps in a celestial cataclysm. A vertical, multi-stage astrophysical infographic illustrating the sequential mechanics of a core-collapse (Type II) supernova event inside a massive star. The diagram details the transition from an onion-skin elemental shell structure down to gravitational collapse and the asymmetric explosion mechanisms against a deep black space background: Top Stage: A massive evolved supergiant star is shown in a three-quarter cutaway, detailing its interior concentric shells of advanced nuclear burning (the &quot;onion-skin&quot; model). A callout lines up with the innermost zone, zooming in on the dense iron core where black vectors point inward to represent overwhelming gravitational pressures attempting to trigger core collapse. Middle Stage: A secondary circular callout details the moment of core collapse. The central core has imploded into an ultradense stellar remnant (neutron star or black hole), while white arrows blast outward against the inward-rushing outer layers, showing the bounce shockwave mechanism. Bottom Left Stage: The shockwave propagates unevenly through the star&apos;s remaining envelope, showing the early development of an asymmetric, butterfly-shaped stellar explosion with white outward-pointing expansion vectors. Bottom Right Stage: The final phase details the violent, fully developed supernova remnant expanding rapidly into a non-spherical nebula of gas and dust. A prominent central arrow indicates the rapid space-velocity &quot;kick&quot; given to the central compact stellar remnant as it is ejected from the center of the asymmetric blast zone.Artwork © 2007 Don Dixon / cosmographica.com</image:caption>

An abstract, geometric visualization depicting theoretical concepts of string cosmology and brane multidimensional space. A warped, translucent orange surface representing a dynamic cosmic membrane or &quot;brane&quot; curves down over three metallic spheres of increasing size resting on a flat, light blue plane. The minimalist 3D rendering uses clean lighting and shadows to represent complex mathematical ideas like higher dimensions, bulk space, or parallel universes interacting within a multiverse framework.

			<image:title>Caesareum Temple in Ancient Alexandria</image:title>
			<image:caption>The Caesarium (or Caesareum) was a temple built by Cleopatra VII to commemorate the deification of her murdered lover Julius Caesar and to honor her husband Marc Antony. When Octavian, Caesar&apos;s heir, conquered Antony and occupied Alexandria he destroyed every statue of the &quot;Egyptian whore&quot; but preserved her monument, rededicating it to himself. So travelers entering Alexandria&apos;s harbor might notice the temple he set before it two fifteen-centuries-old pylons from the temple of Ra in Heliopolis, one of which now stands behind the Metropolitan Museum in New York&apos;s Central Park and the other in London&apos;s Thames Embankment. Until the middle of the 4th century the Caesarium was the center of a temple complex that included gardens, lecture halls, and satellites of the Great Library. Converted to a Christian church in the late 4th century, The Caesarium served as headquarters to Bishop Cyril who led a campaign to stamp out all non-Christian influences in Alexandria. The philosopher Hypatia was murdered on the steps of this temple in March, 415. The artist&apos;s reconstruction above depicts how the temple might have looked during late afternoon on 15, March 415 A.D. A print of this image is available.

			<image:title>Fast Radio Burst Magnetar</image:title>
			<image:caption>[frb_fin_001] Fast Radio Burst (FRB) — This scene illustrates the &quot;starquake&quot; model of a magnetar, a type of neutron star with an ultra-strong magnetic field. The artwork depicts a rupture in the stellar crust, which triggers a catastrophic reconfiguration of magnetic field lines and the subsequent release of a Fast Radio Burst (FRB). The resulting emission is shown as a high-energy plume of radiation erupting from the fractured surface into the magnetosphere. Illustration by Don Dixon. [Publication History]: This illustration was prominently featured in the June 2019 issue of Astronomy magazine to accompany the article &quot;Cosmic Firecrackers,&quot; which explores the origins of Fast Radio Bursts. It is also documented within the artist&apos;s &quot;Exotic Stars&quot; digital archive.</image:caption>

			<image:caption>[504] Binary Black Hole Merger — An illustration by Don Dixon depicting the merger of two stellar-mass black holes and the resulting emission of gravitational waves. The scene visualizes the final stages of a binary inspiral, where the orbital decay of the singularities creates intense ripples in the fabric of spacetime, rendered as concentric, glowing blue and white distortions against a multi-colored nebular background. This digital has been utilized to represent the astrophysical events detected by laser interferometry. Interior painting for November, 2017 Astronomy Magazine shows the space-time distortions produced as two black holes merge. © Don Dixon / cosmographica.com</image:caption>
