This beautiful space wallpaper is a photo illustration based on a Hubble Space Telescope survey of evolving Milky Way-type galaxies. The current night sky is dominated by the white glow of myriad middle-aged stars along the lane of the Milky Way.

Thousands of stars appear as pinpoints of light throughout the sky.
