Envision a grand celestial observatory perched on a mountain peak, its ornate domes glimmering under a blanket of stars. Ethereal light filters through vast stained glass windows, casting colorful patterns across the marble floor. Astronomers in vintage attire gather around intricate brass instruments, their faces illuminated by the delicate glow of distant galaxies. The night sky is alive with swirling nebulas and shooting stars, embodying the mysteries of the universe.
