Reloj de arena cósmico que fusiona galaxias, estrellas y tiempo

Create a mesmerizing double exposure image that intertwines celestial bodies, such as galaxies, stars, and planets, with a clock or hourglass to symbolize the passage of time in the universe. The clock or hourglass should be partially transparent, revealing the stunning cosmic scene within. The artwork should evoke a sense of wonder about the vastness of space and the concept of time.
