Cosmic Hourglass

In a vast, empty desert, a lone figure stands with their back to the viewer, gazing at a colossal hourglass suspended in the sky. The hourglass is filled with shimmering cosmic dust that cascades downwards, forming a starry river that flows into the horizon. The sky is painted with swirling galaxies and nebulae, creating a cosmic tapestry of vibrant colors. The scene is infused with a sense of timelessness and mystery.
