Hello, returning player here.

Hiya commanders! I havent played since 2018 but recently got back into it, and I've been exploring like nuts! I got a thargoid question? Can they show up outside of invaded territories? I was around Ueon, getting back from an expedition and I picked up a lot of nonhuman signals in a star system? I didnt check it out cuz I was in a hurry to get home, and didn't want to risk loosing 25mil in data

Edit: Nuen! I meant Nuen, dunno where Ueon came from lol
