No more spacecrafts on a black background! This blend includes a procedural stars background for Cycles. Blender Internal includes one option in the world settings, but cycles engine doesn't.

The background is not perfect and in some points there are too much saturated galaxies. You can avoid them easily by rotating the clouds pattern coordenates in the background settings.

Map moon image is not packed in the file, as I'm not sure with its rights. If you want you can look for it in your web search engine.

This images has no compositing. You get what you see. There is a high res version with compositing [here](http://elbrujodelatribu.deviantart.com/art/Moon-between-Galaxies-384810931). And a brief explanation in [my blog](http://elbrujodelatribu.blogspot.com/2013/07/blender-cycles-procedural-stars-world.html).

EDIT: @shadow12312gx has made an animation with this World settings:
