Hourglass reflections

An ancient, ornate hourglass filled not with sand, but with a swirling nebula of cosmic dust and distant galaxies. Starlight spills from the glass, casting ethereal reflections onto a polished obsidian surface below. The scene is depicted in a hyperrealistic style, emphasizing the profound depth of the cosmos and the intricate details of the hourglass, with a focus on how the light from the nebula creates shimmering, otherworldly refractions.
