Depict a futuristic underwater city beneath Europa’s icy surface, designed like giant, floating metal jellyfish. Translucent, dome- like structures glow with soft, bioluminescent light in shades of blue and purple, blending organic forms with cybernetic technology. The city floats through the ocean depths, suspended by mechanical tendrils resembling jellyfish tentacles that extend downwards, absorbing geothermal energy for power. These structures feature smooth, circular designs, with semi- transparent walls exposing intricate inner machinery and energy conduits. Smaller platforms and glowing arches connect the domes, forming a network of fluid, flowing architecture in harmony with ocean currents. The deep ocean is dark and expansive, with only the faint illumination of Europa’s icy surface filtering through. Cinematic lighting enhances the city’s ethereal beauty, casting a serene, otherworldly glow on the scene. "
