preserving our dark skies

I haven't heard of this before but it makes sense (there is a "dark sky" association that lobbies for night sky conservation, see HERE).

Anyway, I found a similar article about preserving dark skies, HERE.  It is worth checking out.  I've left the photo above in a larger size (courtesy of the article) in case readers would like to click on it in order to view it in greater resolution.  It is an example of how darkness and the night sky can be quite beautiful.
