Battlestar Galactica (Fri, 10PM-11PM, Sci Fi Channel)
At long last, the best sci-fi show on TV is back for its fourth and final season.

Egypt's Ten Greatest Discoveries & Why Ancient Egypt Fell (Sun, 8PM-11PM, Discovery Channel)
Discovery Channel has a couple of interesting new specials Sunday night. First up is a two-hour program which features host Zahi Hawass and a team of archaeologists picking the ten most important finds made in Egypt. This combines two of our favorite things: Ancient Egypt and top ten lists! Also, we love Zahi Hawass. The second hour-long program features archaeologists trying to determine what could have caused the collapse of the powerful Egyptian empire.
