The Photopic Sky Survey: An Interactive Photo Survey of the Night Sky
"The Photopic Sky Survey is a 5,000 megapixel photograph of the entire night sky stitched together from 37,440 exposures. Large in size and scope, it portrays a world far beyond the one beneath our feet and reveals our familiar Milky Way with unfamiliar clarity. . . . Seen at a depth thousands of times more faint than the dimmest visible star, tens of millions of other suns appear, still perhaps only a hundredth of one percent thought to exist in our galaxy alone." It's beautiful. [rdbrewer]
