Downloaded and installed ..really nice quality if you adjust it under Settings. Thanks for sharing

Wow, you really need to know your stuff to make this thing work. Very cool graphics once you figure out how to move things around.

One challenge I foresee is everytime to want to watch a tour you need to download it one tour was 5mg, this could get pretty hefty on the computer if you get into it.

Very cool idea, will spend some more time trying to get it to work.

Took a couple of the Black hole guided tours... totally awesome! I felt like I was at one of those space/science centers that have galaxy shows on the ceiling.

Just imagine the quality of education one can get on space from anywhere with an Internet connection. I can't wait to see what they do with it.

Andy thanks for sharing I downloaded it during lunch and checked it out I have been waiting for this to come out since I heard about it last month. The really cool thing is I can even check out the night skies in your neck of the woods and I don't even have to be there it's going to really give the classroom a new way to show the stars.

The audio ads the extra bonus that you don't get out of the other tool out on the net.

Great move from Microsoft and TED.

Awesome stuff, the guided tours rock! Feature request: Ability to set as screen saver with random guided tours!

It is a great program. Familiar design, runs smooth and no crashes for me. Already beats the other stuff i've used ;)

Very nice but it remains a windows only application...
I wont use it. Google has the same thing that works on all platforms.
