Anthony Handley has some great content over at his blog, and from there I learned about something called the "worldwide telescope" being developed by Microsoft Research as a free download at http://worldwidetelescope.org sometime this summer. This stitches together a 3d view in an all around the earth view of stitched together pictures from the worlds best telescopes in a completely immersive environment.

If you can't wait you can check out the video of the "worldwide telescope" in a video preview at (Standard Def) and (high def) download. I highly recommend Anthony's blog UXConfidential, he is an excellent UX Designer/Developer as well..

PS Oh and yes, some of these videos are done in Flash, just in case anyone was wondering..
