White glowing spheres in the dark

Three white glowing spheres arranged vertically against a pitch-black background. Each sphere emits a soft gradient light that blends smoothly, giving a sense of depth and layering. The top sphere is the largest, with a subtle glow surrounding it, while the two spheres below decrease in size and brightness. The overall composition emphasizes softness and minimalism, with a futuristic and abstract aesthetic. The spheres appear to float, creating a calm and mysterious atmosphere that draws attention to their light and form.
