Confession: My husband and I do not have cable, but we do have favorite shows that we watch by streaming over Netflix or Zune. The heart of this confession is this - we are major documentary junkies, especially for science documentaries. Our very favorites are those about stellar astronomy. We loved History Channel's The Universe, and watched every episode we could get access to. Yesterday we started watching Discovery Channel's How the Universe Works.
We highly recommend both of these series. Go ahead - indulge your inner nerd!!
