Neptune The Astronomical Art of Don Dixon

448-neptune-from-triton-dixon –This detailed visualization looks across the rugged, icy cantaloupe terrain of Neptune's largest moon, Triton. In the middle ground, a powerful cryovolcanic geyser erupts, lofting dark nitrogen gas and dust high into the thin atmosphere where it begins to drift horizontally. Hanging in the starry sky above the fractured horizon is the gas giant Neptune, showing its banded blue atmosphere, Great Dark Spot, faint high-altitude clouds, and subtle ring system.Commisioned by Griffith Observatory for an exhibit.

394-neptune-rings-diagram-dixon –This three-quarter view diagram illustrates the structure of Neptune's dark, dusty ring system and its small inner moons. The gas giant is centered within concentric rings composed of fine debris, highlighting the localized clumps or "ring arcs" embedded within the outermost Adams ring. A small trailing alignment of inner shepherd satellites is depicted orbiting near the ring planes against a pitch-black background. for Scientific American

Migration of Neptune's Orbit, version 2

365-early-neptune2-dixon –This space art composition visualizes the chaotic formation of the early Neptunian system during the Late Heavy Bombardment. The proto-Neptune is depicted with a molten, glowing crust heavily scarred by bright kinetic impacts, surrounded by a thick primordial debris disk of dust and rocky fragments. A large, irregular asteroid-like planetesimal dominates the immediate foreground, while the distant young Sun encircled by comets shines in the distance.

212-triton-surface-dixon – This low-angle landscape perspective looks across the undulating, frozen plains of Neptune's largest moon, Triton. The foreground showcases hummocky terrains and fractured ridges composed of water ice and frozen nitrogen, bordered by a vast expanse of rough, snow-like frost fields. In the hazy, twilight-lit sky above the flat horizon, the massive, softly blurred disk of the blue gas giant Neptune looms prominently, showing vertical atmospheric banding.

Neptune from Triton

052-neptune-dixon – Neptune in the sky of its large moon Triton; This visualizes the surface landscape of a Neptunian moon, offering a dramatic look across an expanse of rugged, brown rock formations and icy plains. The stark horizon is dominated by the colossal, pale blue disk of the gas giant Neptune, showing subtle atmospheric banding and a soft limb glow against a dark star field. The composition captures a pre-Voyager scientific view of the outer solar system's extreme scales. acrylic and goache on illustration board ; 1974. © Don Dixon
