I still feel like the signals source might be out there and this might become another mystery to solve. I wrote this in another Thetis thread so I'll just copy and paste it over:
So lets say they recieved the message in a system about 15LY away from Nefertem. As AstroExplorer67 stated (quote down below), there is only one system which is so close and relatively aligned to Sol. LFT 698.
So Astro had the idea to check the third planet, first moon because of the binary code. I just got to the system but instead, I checked if planets lie between Sol and Nefertem
because they literally said the passed the planet, 15LY ago - and indeed there is Planet 4 with its 6 moons. I like the binary theory so I will check out the third moon, now.
(Checked an area for around 3 hours, nothing except a few data points and crates) but I will continue the search later on)

I also made a video about the ship if someone is interested in hearing the voices with nice visuals:
