Here is the prompt:

“Render a 3840×2160 celestial canvas of swirling purple and blue nebulae, set against a velvety black background, with delicate wisps of gas and dust shimmering like diamonds. Against this cosmic tapestry, depict majestic constellations in silver and gold, their lines etched by the brushstrokes of ancient mythology. A radiant Milky Way arches across the top, its curves glowing softly as if illuminated by an unseen moon. At the center of the canvas, a magnificent Andromeda Galaxy rises like a celestial jewel, its spiral arms glinting with stardust and shooting stars. In the distance, a scattering of smaller galaxies and star clusters twinkle like diamonds on black velvet, while wispy tendrils of interstellar gas stretch out like ethereal tentacles, as if beckoning the viewer to explore the infinite expanse of the cosmos.”
