PROMPT:
Create a mesmerizing sci-fi artwork depicting a sprawling, ancient alien metropolis hidden within the heart of a nebula, illuminated by radiant, iridescent lights that dance across the wispy, ethereal clouds. Incorporate vibrant colors, excluding pink, to emphasize the extraterrestrial environment's mystique. The structure's organic, glowing architecture should appear worn, as if carved by an ancient civilization, blending seamlessly with the surrounding celestial matter. The atmosphere should exude an otherworldly essence, as if frozen in time. Render the image in photorealistic detail, with intricate textures, subtle reflections, and a sense of depth that invites the viewer to explore the mysterious, forgotten world.
