Hakuou to the Stars troch DxSepley

The name makes no sense, but it's just a picture of Earth (viewed from Celestia, sans blackness of space via layer mask) superimposed over a color-adjusted (more blue, green, and cyan) picture of the Carina Nebula. Despite the CC-license that Mozilla attaches, the header is made of NASA Material and should be in the public domain. At least the Carina Nebula part is. Not sure about the Earth.
