Microsoft WorldWide Telescope

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.

The software utilizes Microsoft's Visual Experience Engine technologies to function.[4] 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.
