Colonies, Minings -> Money

First source for money is to colonize stars. After building a colony the star will give you its income (see the picture above) every hour.

Second possibility to get money is to build minings on stars that have asteroids. To build minings you first need to get mining technology.

Factories -> Capacity

To build ships you need money and capacity. To get capacity just build factories. Productivity of a star shows how many factories it is wise to build on a star. Factories above that limit will generate less capacity, just 40% of normal.

Labs -> Tech-points

To get tech build labs. Every lab produces 1 techpoints per hour. But you cannot produce more labs than the star's tech (see the picture above).
