from the galaxy to subatomics

Wow, jenna2 emailed me this link http://micro.magnet.fsu.edu/primer/java/scienceopticsu/powersof10/index.html to a series of pictures that zoom in step by step from a view of our Milky Way galaxy to an imagined subatomic view of a proton at the level of quarks. I always wanted to do something like this. It is very cool.
