Hi I've been playing this game for a week or so now, but I still haven't managed how to get my ships to jump from one system to another.

Scenario: 5-system game. I'm kicking arse all over one system, but see there are planets colonised by other civs and scouts turning u from who knows where. Why is that? I look for phase lanes, can't see 'em, I send my ships to the sun and try right clicking to send them other stars, but it doesn't work. Do I have to unlick tech or something?

thanks to anyone who helps me.
