The Beta Triangle

The Beta Triangle is known to the Colonials as an "Extreme Hazard to Shipping" for both the fact that its apex is that of a black hole and its known "infestation" of pirates who prey on wrecked ships for salvage and other goods.

Galactica and her Fleet encounter barrier waves from the Triangle, resulting in damage to a Gemini freighter. The Triangle is also monitored by Cylon sentinel buoys (The Beta Pirates).
