The Lagoon Nebula is a stellar nursery about 5,000 light years away towards the center of the Milky Way. The Nebula itself spans a distance of about 50 light years. Link to picture.

Smashing Magazine has a Killer collection of Space Themed Wallpaper links for your enjoyment. Some appear to be artist representation, while others are shots from the Hubble Heritage Project (which by the way has an great collection of wallpapers in itself). Also be sure to check out the Hubble site archives which contains a crap load of wallpaper sized images from Hubble taken over the years (one of my personal favorites).
