139-io-sodium-aurora-dixon - A dramatic vista from the highly volcanic and rugged surface of Io, looking across a jagged, rocky canyon landscape. A colossal, half-illuminated Jupiter hangs in the dark sky, its dense cloud bands and iconic Great Red Spot visible along its day-night terminator line. To the left, a luminous, orange-glowing cloud of neutral sodium atoms forms a vast magneto-atmospheric nebula, interacting with the Jovian magnetic field and casting an eerie glow over the star-flecked background. 6x7 inch acrylic and gouache on illustration board, 1984. © Don Dixon
