This is the mid-season finale. Unlike those of the second and fourth seasons, this lasted only a month, making it the shortest of the series' run. As a result, the Region 1 DVD set was released in whole, much like the first season, which had no break (excluding the miniseries).

According to Jane Espenson, who wrote the previous episode, this episode was originally titled with the name Zeus. Ron Moore explained that it was changed later to Jupiter simply because it sounded better.

The temple's interior is the same abandoned factory that served as the large room on Ragnar Anchorage where Doral is left at the end of the miniseries.

The episode's teaser runs past 11 minutes, making it the longest teaser of the series thus far.

Despite having appeared in several episodes together, this marks the first time Boomer and Athena are seen meeting and interacting with each other.

Number Six: It feels like old times, doesn't it?
Baltar: I can't believe how much I actually miss this place.
Number Six: You know you can't return. They'd toss you out the nearest airlock, and then throw a party.
Baltar: Yes, I know. Still, I can't help feel I'm finally... home.
Number Six: If you're really a Cylon - a member of the Final Five - these feelings are just part of your programming, part of your cover.
Baltar: And if I'm a human being after all - if I'm not one of the Final Five, then this is the last chance I get to see my kind again.

(Baltar and three Cylon models are being escorted when they run into Athena)
Athena: Colonel, wait.
Cavil: Well, look at this. Should we salute?
Athena: (indicating an Eight model) That's Boomer.
Tigh: The one who shot the Old Man. Well, you just lost your visiting privileges.

Adama: What's your offer?
Number Three: You give us the Eye of Jupiter, we let you go.
Cavil: And, we'll throw in Baltar.
Baltar: What are you talking about?
Number Three: Indeed.
Baltar: What's he saying?
Cavil: I'm improvising. Throw in something, sweeten the pot. Besides, I suspect that the Admiral and Madam President would enjoy some nice, quiet, private time with the former leader. Am I right?
Tigh: It's worth thinking about.
Adama: Definitely worth thinking about.

Kara: Can I make a suggestion that you won't like?
Lee: Do you make any other kind?

Gaeta: Sir, I am not one to look to religious signs, but I can't get my head around these odds. That human and Cylon both converge on this planet, at this exact moment, just as the star's about to go supernova?
Adama: I'm not a religious person, Mr. Gaeta, as you both know. So if this is the work of a higher power, then they have one hell of a sense of humour.

Helo: You, of all people.... know what it's like to loose a child.
Adama: The difference is your child's still alive. And eventually, I hope you become grateful of that.
