After long waiting since the talk by Roy Gould and Curtis Wong in Feb 2008, Microsoft WorldWide Telescope is finally available for download.
This is a really great art of masterpiece. It features the photos taken by ground-based observatories and space telescopes. There’re terrabytes of images at research grade resolution. I am not sure how to do research with it but it’s totally full of marvelous sceneries. Beware, your harddisk might be filled up with all these images. 
It also allows you to point your telescope to the target you currently focus on by installing the ASCOM component. This software certainly comes in handy when we do public outreach.
Explore it yourself!
PS: I’m going to do a review of this stunning virtual telescope soon.
