Futuristic Nebula

A vibrant depiction of a futuristic nebula, with swirling colors of emerald green and sapphire blue. The top of the image is a deep black void speckled with stars, and a bright comet streaks across. The colors blend into a gradient of fiery red and orange towards the bottom. Silhouetted against this backdrop on the left are abstract shapes resembling distant planets, outlined in neon pink and yellow. The style is distinctly retro-futuristic, echoing the bold color palettes of 1980s science fiction.
