Photorealistic Supernova Snow Globe

Photorealistic scene inside a crystal-clear snow globe: a miniature cosmos suspended within glass, featuring a brilliant supernova at the center exploding in magenta-pink and fiery orange with a halo of electric blue. Surrounding it are wispy nebulae, dust lanes, and a field of tiny stars, while delicate glittering snowflakes swirl around, refracting the stellar glow and creating sparkles on the curved glass. The globe sits on a dark, carved wooden base with a subtle brass trim. Soft ambient lighting from above contrasts with the intense inner glow, producing realistic reflections, glass caustics, and depth of field. Render in ultra-high detail (photorealistic 8k), cinematic lighting and micro-detail such as rim highlights and slight frosting on the inner glass for realism.
