Do you remember this from Douglas Adam's Hitchhiker's Guide to the Universe?:

Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.

You can now experience that a little bit. Microsoft released a preview of it's WorldWide Telescope software. But don't try this at work. You probably won't get anything done today
