The Beta Triangle is a large area of space that has at its heart, a very large black hole. This in itself would be a navigational hazard for ships, but compounding this further is the fact that the black hole routinely gives off very damaging gravity waves that make the area of space more dangerous. Add to this the fact that there are many rogue and loose asteroids and planetoids that have not been mapped, and the area is considered avoidable if at all possible.
Colonial and Cylon forces tend to steer clear of the area as travelling within it is a sure way to damage and destroy ships, especially as the rogue objects within its sphere have not been mapped at all. Guides can be found to travel around the edges of the Triangle, but travellers are advised to be wary of old maps of the area as nothing stays still for long enough to be mapped successfully for a long period of time.
However, for precisely this reason, the area is a haven for pirates who make their bases on the many spatial objects found within. Pirates found here are generally considered the more dangerous of the lot as to have survived to make a base of operations here requires some considerable skill and courage, as well as a drop in sanity. The pirates that do operate here are skilled as dropping onto asteroids for cover against the more fierce gravity waves, and most ships are more heavily armoured than normal.
The Magnetic Void is a vast area of space where normal sensors and communications do not work. Everyone knows of its location, but no one ventures there as no one has ever returned. Whilst this magnetic void is the largest known, it is not the only one present in this part of space.
Voids are very dangerous. They confuse sensors, making them useless, and communications soon lose their range and break up. Once inside the void, there is only blackness, and the further you travel, the deeper this gets. It is very rare to actually find anything within a void, but occasionally rogue planets ore asteroids can be found there, trapped by the void. The stars can only shine so far inside a void and as a rough guide, when you can not see the stars anymore, you most definitely can not communicate outside the void, or vice versa. With communications, sensors and electronic readings disrupted, combat and navigation literally becomes a line of sight affair with a pilot trusting to skill and eyes rather than to what his useless sensors are telling him.
While Cylons sensors are also affected, a Cylon itself is not disrupted by the void.
The Nova Madagen is not actually a nova at all, but instead is a very bright starfield. In addition, this starfield gives out a lot of heat that can be damaging to slow moving craft or small vessels like shuttles and fighters. These small vessels are restricted even more by the fact that their cockpits have to be sealed so as to not allow the pilot to physically go blind and to protect their occupants against the heat. Generally the only way these craft will be able to get through the starfield is if they are piloted through the field by the mother ship.
This Nova Madagon is a naturally occurring phenomenon surrounding most of the navigation routes around the planet Carillon, and allows only one safe access to the system.
Around 7300, the Cylons started mining the Nova Madagen to stop any such access through it.
Some worlds and planets sometimes get covered with mist or clouds. These resemble vast fog patches that sometimes travel on solar currents. They are called space storms or astral winds. More often though, they just form around planets, being collected by the pull of the planets gravity, and then they dissipate after a while. They are not damaging to a craft passing through them, but they do block visibility and can interfere with a crafts scanner.
