PROMPT:
Create a mesmerizing image of a cosmic hub, Nebula Nexus, where swirling clouds of iridescent gases converge. Employ vibrant colors, with an emphasis on turquoise, emerald, and amber hues, while subtly incorporating deep blues and purples to evoke an otherworldly atmosphere. Minimize the use of pink tones. The result should appear photorealistic, as if gazing through a cosmic portal. Portray the nebula's center radiating an intense, celestial energy, pulsating with an ethereal light that illuminates the surrounding clouds, casting an aura of mystique and wonder.
