It's called a protostar.

I'm gonna make like 10 colonies on 10 different planets with uber turrets right near the center of the galaxy. Tell me this plan owns.

I made one colony (used the Staff of Life) on the Grox planet closest to the center.

Nice.

And wtf? I put an uber turret on my planet and the Grox still killed it.

Uber turrets die... they have 50,000 health. And also, they don't help that much. A waste of money in my opinion.

But I heard that they make it so a planet can't be attacked....

You heard wrong. They make it harder for an attacking force to conquer the planet by increasing defence.

GAAAAAAAAAYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Grox vs any amount of turrets including uber - Grox win.

The Uberturret, IMO, is frekin' awesome. I see a "Your planet's being raided/attacked!", and 2 seconds later, "Your planet is no longer being attacked!".

IM GETTING PISSED OFF WHERE IS SOL????????????

As it turns out, I am on the wrong arm of the galaxy to get to Sol... so it's not gonna be easy...

Sol is in the EXACT SAME PLACE on EVERY computer. Watch a tutorial.

I did that... I found and went to the Orion Belt, yet never found it. I flew to EVERY DAMN PLANET around there. Nothing.



*EDIT*

Nevermind, found it.

When I was going to another saved games planet, I was rushing the mouse around to find a path around a huge freaking gap (only haveing instellar drive 2), The mouse rushed passed a Star system which I think said Sol on it.
I found a way around the gap and clicked a bunch of star systems to the planet I was heading for, And I stopped and thought, Hold on, did I just pass by Sol? I turned around and searched but found no star system named Sol.

So close .

oh yeah, I made it to the center of the Galaxy (long after when i had instellar drive 4)!

In the file select screen, spin the galaxy very quickly and pictures pop out of the center of the universe.
