Curving Cosmic Ribbon of Plum and Golden Stardust in Lower Vertical Third

Full prompt

An expansive 16:9 landscape astrophotograph framed for an editorial feature, displaying a gentle curving ribbon of plum, rose gold, and deep sapphire stardust flowing across the panoramic cosmos. The celestial stream sweeps horizontally across the lower and central field, its iridescent gaseous tendrils illuminated softly by embedded stellar nurseries that cast gentle highlights along undulating crests. Above and around the primary arc, vast obsidian space stretches outward, punctuated by minute crystalline stars and diaphanous whispers of background nebular mist. Low-key, contemplative lighting preserves pristine tonal gradations and crisp edge definition along the cosmic dust rifts. The horizontal vista emphasizes majestic astronomical scale, fluid continuity, and quiet celestial serenity across the wide frame.
