Prompt
A nebula-like burst of vibrant particles expands from a central soft core, blending deep blues with neon orange, emerald, and pale violet. Wisps of glowing filaments spiral outward, merging into misty clusters that gradually fade into a dark void. The structure holds a loose circular shape but remains organic, like cosmic dust in motion. A subtle gradient enriches the center to maintain focus while outer regions stay free for background purposes. Cool ambient light softens transitions between colors, creating a dreamy atmospheric feel. Foreground particles stay crisp while distant ones dissolve.
