After watching the short videos on the site, all I can say is I really cannot wait to start playing with this and cut my kids loose. I can tell you that this is going to service that gets a lot of utilization. From the Microsoft website is this statement.
“The WorldWide Telescope (WWT) is a rich visualization environment that functions as a virtual telescope, bringing together imagery from the best ground and space telescopes in the world for a seamless, guided exploration of the universe.
WorldWide Telescope, created with Microsoft’s high-performance Visual Experience Engine™, enables seamless panning and zooming across the night sky blending terabytes of images, data, and stories from multiple sources over the Internet into a media-rich, immersive experience.”
So come on Microsoft cut it loose. wwtelescope.com
