WorldWide Telescope has garnered rave reviews in the press, support from educators and scientists across the globe, two award nominations, and nearly 2 million regular users. it now has 25 terabytes of data and imagery in the “cloud” – huge Microsoft data centers that make it possible to access tremendous amounts of data from nearly anywhere. For comparison, one terabyte will hold about 1,000 copies of the Encyclopedia Britannica. Additionally, Fay also has implemented three-dimensional viewing. Users with anaglyph glasses (which convert side-by-side images into a single stereoscopic image) can fly through the large-scale structure of the universe, the valleys of Mars, or the panoramas from the Mars rovers – all in 3-D. Users also can create and take any number of intergalactic tours hosted by astronomers, educators, or students, Wong said.
