A breathtaking underwater scene resembling a galaxy, deep in the ocean's depths. Bioluminescent marine life mimics celestial formations, with glowing jellyfish floating like distant stars and swirling schools of fish creating nebula- like shapes. The water is an inky blue, fading to black, with shafts of light penetrating from above, illuminating the ethereal underwater galaxy. Coral formations, resembling alien planets, glow faintly with vibrant hues of blue, green, and purple. The composition captures a surreal, cosmic vibe, blending aquatic and astronomical elements seamlessly. The color palette is rich and luminous, featuring neon blues, radiant purples, and soft pink highlights. The atmosphere is otherworldly and tranquil, evoking wonder and mystery, as if the ocean itself holds secrets of the universe. Fine details, such as shimmering particles suspended in the water and the soft glow of bioluminescent creatures, add depth and realism to the scene
