A physically plausible young solar nebula / protoplanetary disk seen obliquely from space, the young star forming at its center at left-middle, dense flattened disk of dusty gas with subtle uneven warm illuminated bands and dark lanes, very tiny grains rather than a belt of oversized boulders, deep natural black starfield, sparse stars, volumetric light scattering through real-looking fine dust. Authentic natural history / observatory reconstruction, realistic muted gray, bronze, ember and blue-black, wide scale, optically plausible, restrained light bloom not fantasy. Leave lower fifth darker for UI. No existing planets, no modern Earth, no rings around a planet, no exploding star, no cartoon, anime, low poly, toys, neon artwork, letters, labels or watermark. The disk must extend around the central star in a flattened plane, not a spiral galaxy.",

One complete spherical rocky protoplanet, centered with margin, primitive Earth during a strongly molten phase: detailed turbulent orange-yellow molten silicate surface with dark irregular basalt-like cooling rafts, finely branching incandescent fractures, craggy uneven rock texture, realistic physical lighting and self-shadow, no smooth solid red sphere. No present-day continents or blue oceans, no greenery, no snow, no faces, no stars or external objects. Planet lit from upper left, right limb in deep shadow, very thin smoky volcanic haze close to sphere only, subtle hot emission, photographic natural science CGI rather than illustration. Optically spherical, not a ball on a floor. Avoid cartoon, low-poly, flat art, magic, labels, text, watermark, candy saturation. Alpha transparency around planet; keep haze subtle to preserve silhouette.",
