Everyone check out this Planetarium software. It's free and currently in beta. You can travel anywhere you like in the Universe and it gives you a great sense of scale of how big and far everything is.

Download it from the Google Drive link. It will warn you about Google Drive not being able to scan for viruses but don't worry about that. The install is clean and I did my own scan.
