Edit: Never mind, I just figured out how to just seconds after this post. Ironic. But is it normal for all the jump points to say 'Unex'? Does this mean ALL of them go to that one system?
Also, I vaguely remember needing some other kind of sensor aside from grav survey sensors in order to detect ships and home worlds and whatnot. What would you recommend, for a ship to explore beyond the solar system and investigate?
