I was surprised in myself being able to name some of the terms that came up in this episode. I feel dumb; I just discovered that the show is somewhat based on Sagan's book called [wait for it...] Cosmos. This is by far my favorite new show of the season, and I hope that it remains, whether or not the ratings are strong.
Not certain if it'll be back or not for a second season. From what I've read I've been getting the impression that this may have always been intended as a "one and done" season type show like the original Cosmos. Not certain how well its been doing ratings wise, but I can't imagine it being too high. The Sunday premieres on Fox were/are competing with The Walking Dead/Game of Thrones and the Monday re-airs are on National Geographic Channel at the same time as The Voice, Mike & Molly, The Following, etc.
