Created by Microsoft, the WorldWide Telescope sports a high performance Visual Experience Engine and allows seamless panning and zooming around the night sky, planets, and image environments.
The WorldWide Telescope (WWT) enables your PC to function as a virtual telescope, bringing together imagery from the best ground and space-based telescopes in the world. A web-based version of WorldWide Telescope is also available now, for preview. This version enables seamless guided explorations of the universe from within a web browser. It’s compatible with PC (requires Microsoft Silverlight 2.0 though) and Intel Mac OS X.
