Reference made to Capella binary star system with one blue and one gold star. Capella is actually a four star system. A pair of massive G type stars, colored like our sun but much larger. And out about 100,000AU is a pair of red dwarf stars.

Beka refers to a charged plasma nebula as "the black goat with a thousand young". Lovecraft associated a "black goat of the woods with a thousand young" with Shub-Niggurath in "The Whisperer In Darkness".
This is an economizing bottle episode. Using only the core cast and only the permanent sets means the episode is cheap and quick to make. A production crew does this when the season has gone over budget or when they want to allocate extra resources to a grand finale.
