Minimalist Void Portal Glimpse

Prompt

Generate a piece of minimalist sci-fi concept art. The composition is dominated by a vast, pitch-black void. In the center hangs a perfectly smooth, white oval portal. Through the portal, we see a vibrant, swirling galaxy of stars and color. A tiny, solitary spacecraft hovers just at the threshold of the portal. The image should emphasize negative space, scale, and the contrast between the emptiness of the void and the richness of the galaxy.
