Aliens and Milky Way to the Guardian for Big Draw

Just sent over some aliens and the Milky Way (as you do) for saturday’s Big Draw workshop.  Bed-time reading at the moment is We Are Stardust, conversations with Stefan Klein.  Fascinating, although thinking about quasars etc makes my head ache.  Come to think of it, quite a few things make my head ache so can’t really blame quasars.
