PROMPT:
Create a mesmerizing Celestial Cipher image with vibrant, electric hues that radiate an otherworldly essence, set against a velvety black background that seems to stretch into infinity. Incorporate iridescent nebulae, swirling clouds of stardust, and glittering constellations that shimmer like diamonds scattered across the cosmos. Depict a mystical, glowing portal at the center, pulsing with an intense, luminescent energy that draws the viewer in. Use vibrant colors, with an emphasis on blues, oranges, and yellows, and only subtle hints of pink. Ensure the image exudes a sense of realism, as if captured through a high-tech telescope on a cosmic reconnaissance mission.
