Things you didn't know you didn't know

The Bad Astronomer's at it again with a great post called Ten Things You Didn't Know About the Milky Way Galaxy. I actually did know a few of those things, but certainly not all. I can do little more than look at stuff like this in absolute wonder. We know so much and yet everything we learn simply points to how much we have yet to find out. If there's anything I feel any sort of reverence for, it's that spirit of inquiry that makes us explore everything from galaxies to the tiniest, microscopic organisms that inhabit our world, just to find out what makes them tick.
