Arc Céleste Lumineux au‑dessus d’une Crête Montagneuse Sombre

A majestic, glowing arc of light dominates the dark silhouette of a rugged mountain ridge, its vibrant turquoise and cyan concentric rings pulsing around a radiant golden core, as a luminous spiral trail rises through the twilight blue hour atmosphere, set amidst a subtle, atmospheric haze and soft light diffusion, evoking a dramatic sky phenomenon, with a blue and gold gradient tone palette, an epic scale, a cinematic composition, and a long exposure photography style, featuring ultra-sharp detail, photorealistic, extremely high resolution, and a vertical 9:16 composition.
