I'd like to replace the current placeholder images with those found on OpenGameArt.org. I have no rights to the current images, and cannot legally release them in any fashion to the public. There are some great space related graphic sets that could suite this game perfectly (at least for the time being).
Here is an existing Space Collection: http://opengameart.org/content/space-game-starter-set
Some nice planets, sun:
Possible Background Nebulas:
These need to be darkened with faded or tileable edges
Please try to remain consistent in the colors, realism, and resolution of the images used. Celestial objects (Sun, Planet, Asteroids) and Spaceships should be grouped with similar themes. The Nebulae and Space backgrounds are optional and need to be modified before use in the game.
