Is there a way to keep the ships of pesky aliens outside my system without destroying them??

Not sure if I want to communicate with my aliens, they have a canny resemblance of the Alien in Alien (The movie).
Not sure if I want to bee invited to their smorgasbord...

None that I know of.

I assume you don´t have a trade treaty with them (possible once relations reach 200+ I belive)? If you have, then shooting down their freighters will not make them happy

Thinking about it, shooting down their ships, no matter what, will not make them happy.

Very true! But, unavoidable, alas. NPRs build gates like mad, and explore
everywhere, even in your territory. I find that rather cheeky, so I blow their
ships to "kindom come" whenever they enter my space. If you leave them
be, they'll be setting up colonies in your systems, even if only mining colonies
at first.
