Create an enchanting scene featuring a celestial observatory nestled atop a misty mountain. The dome shines with vibrant constellations while ethereal light spills from its windows, illuminating ancient, intricately carved stone. Surrounding the observatory, lush emerald trees sway gently, their leaves glimmering like stars. Wisps of cosmic clouds drift lazily through the sky, reflecting a palette of deep purples and blues, evoking a sense of wonder and infinite exploration.
