Create a mesmerizing image depicting an otherworldly marketplace set amidst a swirling nebula, bathed in radiant luminescence. Incorporate an array of extraterrestrial vendors, each with unique, bioluminescent skin patterns, showcasing an assortment of iridescent wares and peculiar artifacts. Vibrant hues of turquoise, emerald, and amber should dominate the palette, minimizing the use of pink. The atmosphere should exude an air of mystique and wonder, as if the viewer has stumbled upon a hidden, cosmic trading hub. Ensure the overall aesthetic is photorealistic, with intricate textures and subtle, atmospheric effects that transport the viewer to this celestial bazaar.
