"Create a mesmerizing digital painting of an expansive space scene, capturing the breathtaking beauty and mystery of the cosmos. The scene should feature a vivid array of stars, nebulae, and distant galaxies, each contributing to a sense of infinite depth and wonder. In the foreground, a massive, ethereal nebula should dominate the composition, with swirling clouds of gas and dust in vibrant hues of blue, purple, and pink, illuminated by the light of newborn stars within. The nebula's intricate details and textures should evoke a sense of awe and majesty. Scattered across the scene, countless stars of varying sizes and colors should twinkle against the inky blackness of space. Some stars should be surrounded by planetary systems, with a few planets visible in the distance, showcasing diverse terrains and atmospheres. In the background, distant galaxies should add to the grandeur of the scene, their spiral arms and bright cores creating a celestial tapestry. A few comets and asteroids should streak across the sky, adding dynamic elements to the composition. The overall atmosphere should be one of serene beauty and profound mystery, inviting the viewer to ponder the vastness of the universe and the endless possibilities it holds. The painting should capture the ethereal glow and infinite expanse of space, evoking a sense of wonder and exploration."
