Photo collection of images based on prompt: A silhouetted astronaut stands atop a wide, iridescent rainbow staircase that leads into a swirling galactic nebula. The cosmic background is filled with vibrant purple and green stardust, a large Saturn-like planet with glowing rings, floating transparent wireframe cubes, and colorful 3D geometric slabs. The style is a blend of 80s retrofuturism, synthwave, and surreal digital art, with cinematic lighting and a psychedelic, dreamlike atmosphere.
