Nebulas

[Katherine1]

A natural phenomena in space. They can range from a sector to tens of sectors. Being within one would, obviously obscure vision, and knock out sensors. You'd also be undetectable on sensors while in the nebula. Electrically charged nebula could have effects like knocking out shielding, or reducing the effectiveness of your systems.

You would also have to deal with re-finding your base yourself. A double-edged sword.
