Stephanie should enjoy this blog:

I was reading Digg.com and someone has posted a digg about a free open source planetarium
. The program is called Stellarium and it's quite amazing. It offers a view of over 100,000 stars and you can coordinate it to your local area. There are groundscapes that you can change and a lot of different ways to look at the starry night.

Here are some screenshots from the program.













It's enjoyable and available for a number of platforms.

Give it a try.
