This image provided by NASA Friday July 16, 2010 shows the famous Pleiades cluster of stars as seen through the eyes of WISE, or NASA's Wide-field Infrared Survey Explorer. The mosaic contains a few hundred image frames -- just a fraction of the more than one million WISE has captured so far as it completes its first survey of the entire sky in infrared light. What's special about WISE is its ability to see through impenetrable veils of dust, picking up the heat glow of objects that are invisible to regular telescopes. So far, WISE has discovered 25,000 never-before-seen asteroids. Of those, 95 are considered 'near-Earth' asteroids.
