Our Ever-Evolving Host | Space Wallpaper

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. Interstellar "pollution" from thick dust lanes can be seen threading through the long band of stars. They are interspersed with a few pinkish emission nebulae from ongoing star formation. Thousands of stars appear as pinpoints of light throughout the sky.
