Imagine a futuristic underwater city floating in the sky, with intricate glass domes allowing sunlight to filter through the depths of the ocean. In the center of this city, a massive, glowing neon jellyfish sculpture pulsates with energy, illuminating the surrounding buildings and technology with its otherworldly glow.

Envision an advanced metropolis submerged undersea, yet astonishingly hovering in the firmament. It flaunts an elaborate network of transparent glass domes that permit the sunlight to sift through the marine depth. At the very heart of this underwater city, a colossal sculpture in the form of a jellyfish radiates with neon lights. The sculpture rhythmically throbs with vibrancy, casting an extraterrestrial luminescence on the neighboring edifices and machinery.
