Celestial Oasis

A tranquil desert oasis under a celestial event. A glowing comet streaks across the twilight sky, leaving a trail of shimmering light. The oasis, with its crystal-clear water and lush palm trees, is a stark contrast to the arid desert surroundings. A group of nomads gathers by the water's edge, mesmerized by the celestial display. The style is serene and harmonious, capturing the beauty of nature and cosmic phenomena.
