I've just started a game passed a tutorial I have only 1 solar system, the circle of my empire reached the other 2 solar systems. But I don't know how to reach them, what to do how to colonize planets there?

The circle indicates population, so has nothing to do with range to the next system.

Generally you click on the space ship next to the planet, then select the fleet you want to move, then right click on the system you want to move them too.



Now I have a question. This will only work where there is an unbroken line to the next system. Where it looks wavey you need a new technology before you can make the jump. What technologies lead to greater range. I tried a couple that looked likely, but still had the neighbouring civilization visiting me, but I couldnt reach them...

Thaanks I have some tecnology as someting with wormholes and with out them. They say they allow to travel to the system threw the wormholes something like that...

Thankyou very much i didn't uderstand at all how to travel through to other star systems...
