I don’t know how you would use this in practical terms, but it sure is a cool website if you are trying to explain what a light year is. Even the space it takes to scroll – with nothing to show, really, except emptiness – demonstrates the absolute void that exists outside our atmosphere.

(NOTE – I DID NOT MAKE THIS WEBSITE).
I can see showing this to middle school kids to not only get an idea of the expanse of our universe but also to impress upon them how small we all are, or really, anyone with any hope of meeting Chewbacca in a galaxy far, far away.
It also shows what is possible on the web.
