Columnar Vertical Nebular Spiral with Ultramarine and Coral Stratifications

Full prompt

A striking 9:16 vertical composition designed for a social story, featuring a columnar nebular spiral curling upward through interstellar space. The swirling gas column rises from a textured foundation of dark cosmic dust veils in the lower third, ascending in stratified layers of rich ultramarine, dusty coral, and soft gold. Dramatic shadows cast by an off-center internal star cluster accentuate the sculptural ridges of the ascending column. The spiral's crest curves gracefully through the midground before transitioning into a quiet, deep navy upper expanse sprinkled with pin-sharp stars, ensuring ideal visual hierarchy for full-screen mobile viewing. Clean spatial distribution, refined color contrast, and convincing volumetric depth imbue the celestial column with commanding vertical presence.
