Using Microsoft’s Visual Experience Engine technologies (which allows smooth panning and zooming of objects in the night sky), the Microsoft Research program will provide images of the following four categories of objects: Earth, Panoramas, Planets, and Sky.
Sky mode provides high-quality images of outer space from data collected by the Hubble Space Telescope and ten ground-based telescopes. Earth mode provides views of the Earth, similar to Google Earth and NASA World Wind.
Planet mode allows users to see the planets Mars and Jupiter, and Earth’s Moon. The Panorama view, as the name suggests, allows users to view panoramas of parts of the Universe.
