Tomorrow is the fall equinox, which always gets me (at least) thinking more about the stars.
Let me pause here for a moment: I moved to Farmington just over a year ago, after living all my previous life in either suburbs or cities. I still can't get over looking up at the night sky, and seeing so many more stars, and how fascinating they are.
So, today's video is a talk from TEDxPhoenix, from Lucianne Watson, talking about light pollution, citizen-science (and how various projects are crowd-sourcing it - want to help discover a galaxy or a planetary system? You can!), and why we should care about how many stars we see in the wild, as it were. (11 minutes.)
