AMNH: After hovering over Mount Everest and the gorges that plunge to the Ganges, you are pulled through the Earth's atmosphere to glimpse the inky black of space over Tibet's high desert... Pulling farther and farther from Earth, you see the deep blue of the Pacific give way to night as the Sun comes into focus, the orbits of the solar system shrink smaller and smaller, the constellations Sagittarius and Scorpio stretch and distort, and, as the Milky Way recedes, the spidery structure of millions of other galaxies come into view.

It gave everyone a new perspective on where they live in relation to others, and we hope the Digital Universe does the same on a grander, cosmic scale.'
