Colonization
In brief:Colonization — an Xterium research: gives maximum number of planets +14 at maximum, up to 14 upgrade levels, cost 1–3 600 000 000 science.

Description
To ensure that new colonies are well maintained and have everything they need, special Colonial Support Centers were established to cluster information concerning each colony on every planet. The number of colonies your empire can currently maintain directly depends on the well-being and development of these very centers.
What it gives
Levels: effect and price
| Level | Maximum number of Planets | Science (price) |
|---|---|---|
| 1 | +1 | 1 |
| 3 | +3 | 3 500 |
| 5 | +5 | 25 000 |
| 7 | +7 | 375 000 |
| 9 | +9 | 7 500 000 |
| 11 | +11 | 300 000 000 |
| 13 | +13 | 1 800 000 000 |
| 14 | +14 | 3 600 000 000 |
Reference levels are shown. The study price is in Science points (values, they grow with the level). It can be instantly sped up with Dark Matter.
Science price and calculator
How much science each level needs:
Calculator: time and instant speed-up
Enter your science and choose a level — we'll show how long the research takes and how much dark matter is needed to finish it instantly.
Formulas verified: time = science price ÷ your science per hour (but no less than price ÷ 5), divided by research speed. Instant completion is calculated by the dark matter for the remaining time. Overlock multiplies the science price (and thus the time and dark matter): each overlock level is pricier.
Overclock (honing)
After the maximum level, the research can be “honed” with star ore — this gives a super-bonus.
Maximum number of Planets · first reset 150 star ore
Each reset adds the bonus on top of the max level; the star-ore price grows with every reset.
