It's so tempting to just blow myself up so I can get back faster but then I'd loose all this lovely exploration data...
I'll reiterate what I said a few pages ago: I strongly recommend we take UA's with us to the planets we go to an listen to them. We have spent a lot of time searching and even if we know which nebula they are in it's STILL very vague, even if, as I suspect, they really are in Merope, the UA's might say something different when we land on a planet with barnacles so it's worth checking.
I say this because it seems likely they are fixed POI's, which means no amount of blue circle hunting is going to find em for us, in which case we'd need some way of being given coordinates, and the UA's have been the aliens mouthpiece to us the whole time, I think they very much want to be found.
