Have just been throwing my must-have applications onto my Windows 7 system and came across a nice surprise. There's a new build of WorldWide Telescope available. Here's the official blurb for those who haven't already tried it out:

Immerse yourself in a seamless beautiful environment.

WorldWide Telescope (WWT) enables your computer to function as a virtual telescope, bringing together imagery from the best ground and space-based telescopes in the world. Experience narrated guided tours from astronomers and educators featuring interesting places in the sky

I notice the website has had a bit of an overhaul, that there's several new sky surveys available, that it now has a 3D fly-around mode for viewing the Solar System and the Milky Way, similar to Celestia, and according to the little tip of the day box that popped up it now supports Xbox 360 controllers, but as it's gone 4 in the morning I'll have to wait until tomorrow and see if its got better support for 120 DPI systems and see if I can see anything else that's new.
