If you want to see stars, planets and other space type things, you may wish to take a look here click here, Asynx Planetarium 2.00, it's on the betanews site (you can access the homepage through the link).
I've not tried it, not really my thing, just noticed it on the site a couple of days ago.
Oh yes, did I mention that it is free.
It is beta software, so it may be a good idea to create a restore point before installing it.
Hope this helps.
