Black Hole Starships - mostly a really cool pop description of black holes but also briefly delves into theoretical starship applications.
Astronomy Picture of the Day: Earth at Night - Power! Earth lit up like a Christmas tree.
November/December Horizons Newsletter - I haven't looked at this one yet but, among other things, it has more reprints of Collier's 1952-4 space articles which are extremely nifty, if a little painful in this era. (That particular series goes back for two previous issues.)
Also, the January/February "double issue" of Analog (which now has exactly the number of pages a single issue used to have and which used to come out 13 times a year and now comes out 10 with 8 being shorter but I digress) which includes a probably overly entertaining discussion of the Real Story behind the geocentric/heliocentric shift in Michael F. Flynn's "The Great Ptolemaic Smackdown and Down-and-Dirty Mud-Wrassle" which, alas, doesn't seem to be online.
