The WorldWide Telescope (WWT) is a computer program created by Microsoft that displays the astronomical sky as maps, the 3D Universe, and earth science data. It can also be used to visualise arbitrary or abstract data sets and time series data, using the power of a PC graphics card to render up to a half million data points. WWT was announced at the TED Conference in Monterey, California in February 2008. Users are able to pan around outer space and zoom as far into any one area as the data will allow. Images are taken from the Hubble Space Telescope and approximately ten earth-bound telescopes. It is possible to view the sky in many wavelengths of light. The software utilizes Microsoft's Visual Experience Engine technologies to function. The program runs under either a Microsoft Windows or a web client based on Silverlight. The program is designed to scale from web browser to desktop to large multi-channel full dome digital planetarium.
