A hyper-realistic macro photograph revealing a mind-bending, miniature swirling spiral galaxy housed within the central cavity of a rough, highly complex rocky geological formation on a microscopic scale. The surface and interior of the rock structure are adorned with exotic, feather-like tendrils and crystalline growths that emit a vibrant, bioluminescent glow in electric blue, turquoise, and lime green. The contained galaxy shines brilliantly with deep cosmic blues, purples, golden yellow, and sparkling white star clusters. Extreme close-up. Hyper-realistic micrograph textures with extraordinary, unprecedented detail. Harsh microscopic lighting contrasted with the ethereal, exotic light emanating from the galaxy inside. Shallow depth of field emphasizing the jagged, rough outer textures. 8k resolution, masterpiece quality, absolute 'wow' factor.
