I'm loving this side panel tattoo of an internal spiral galaxy. It belongs to Valentene Peinhardt, who tells Carl Zimmer her corporeal star systems were inspired by Carl Sagan's Cosmos:

I wanted a tattoo that would embrace my love for astronomy and consciousness of being. I remember years ago realizing the fact that we were made of star stuff when I was watching an episode of Carl Sagan's Cosmos series. Since then, my entire outlook on life has changed.

So cool. More science ink goodness over at The Loom.
