Good morning everybody!
I know there is an error in the map but I'm waiting someone to update it. However you can find the map in the spreadsheet as well.
NOW THE IMPORTANT THINGS:
I strongly think that, reading carefully through all the data we found, we already have hints about how to find the other Ruins.
What I take from the data is that this civilization is very similar to us, or perhaps even less advanced, though they have reached other achievements in other aspects of technology, they were not so advanced in terms of interstellar travels.
So my conclusion is that THE OTHER RUINS MUST BE VERY CLOSE TO THE ONE WE ALREADY FOUND. A near star system, OR EVEN THE SAME ONE: EVEN THE SAME PLANET!
Another reason for me to think this, is that the mission has a time limit. And we know that a time limit not goes well with the size of the galaxy.
No need to go to the other side of the galaxy, like some are suggesting, being very wrong IMHO.
Be careful.
Many people suggest to look to the north of this planet, but is this really the home planet of the aliens? I mean it has no atmosphere and stuff... Maybe this is just an outpost, but yes the other one should be close by.
