PROMPT:
Create a breathtakingly realistic celestial navigation scene set within a luminous, iridescent nebula, teeming with stars, gas, and dust. Incorporate an ancient, mysterious, ornate astrolabe at the center, radiating a soft, ethereal glow, as if it's alive and guiding the cosmos. Surround the astrolabe with a series of gleaming, curved, metallic arms, adorned with intricate, swirling patterns that seem to pulse with an otherworldly energy. The arms should be tipped with gleaming, gemstone-like objects that refract and reflect vibrant, electric blues, emerald greens, and fiery oranges, bathing the entire scene in a kaleidoscope of colors. Use dramatic, cinematic lighting to create an sense of awe and wonder, as if the viewer has stumbled upon a hidden, ancient portal to the universe's secrets.
