Some of us may remember a classic adventure, "Powers of Ten". 

If you've never seen this rather famous video it's a great short watch that starts from earth(Chicago) and a thrilling perspective change as it zooms out over a million light years in the Universe.  At the farther point  our own galaxy becomes not even visible. 

The 2nd portion of the video does a similar perspective on our own human body & skin.
