A realistic scientific visualization of a pressure-resistant atmospheric research habitat designed to operate in Neptune’s upper atmosphere. The structure is compact and spherical, optimized for extreme pressure and wind resistance, made of thick matte metal and composite materials with visible reinforcement bands, bolted seams, and thermal insulation layers. No decorative elements or futuristic styling. Small, heavily reinforced observation ports only where necessary. The habitat is partially buoyant, suspended in Neptune’s deep blue and cyan cloud layers, surrounded by dense gas, wind-sheared clouds, and subtle storm bands. Natural lighting with muted colors, realistic scale, documentary-style rendering, aerospace engineering accuracy, NASA/JPL visualization style, photorealistic, high detail. See more
