It is not actually a nova at all, but is a starfield of intense, blinding brightness; this "nova" also causes electronic equipment problems for smaller craft. The Straits of Madagon, a passage within this area of space, were mined by the Cylons, though these are cleared by a group of three Vipers lead by Captain Apollo (TOS: "Saga of a Star World").
In the separate continuity
The Nova of Madagon lies in between the path taken by the Fleet during their exodus from Twelve Colonies of Man and the planet Carillon. As Carillon was a "nine centon" journey via a more circuitous route, Captain Apollo convinces the newly-reformed Council of Twelve that the only way to avoid the Cylon trap at Borallus was to cut through the Nova of Madagon, destroying the minefield that the Cylons had laid using Vipers and laser torpedoes (Exodus!).
The cockpits were fully covered to prevent the blindness of the three pilots—Apollo, Boomer, and Starbuck—while they cleared a 100 maxim wide path through the minefield to Carillon. The starfield's energies were such that the Vipers' scanners failed, and thus had to be guided by Galactica's sensor suite (Deathtrap!).
- The interior of the nova was created using a one-watt laser reflected from multiple surfaces, in particular Richard Edlund's Saturn Award trophy that he received for his work on 1977's Star Wars.
- The word "centon" is misused as a placeholder for "day" instead of "hour" in Exodus!.
