Astrophysics Technology
Astrophysics is a key technology in OGX. It unlocks new colony slots, additional expedition slots, and access to outer planet positions in each solar system.
Main effects
Astrophysics provides three main benefits:
- Increases the maximum number of colonies you can own.
- Increases the maximum number of simultaneous expeditions.
- Unlocks outer planet positions (1, 2, 3, 13, 14, 15) for colonization as you level it up.
Colonies and expeditions
The table below shows the main progression:
| Level | Max colonies | Max expeditions |
|---|---|---|
| 1 | 1 | 2 |
| 2 | 1 | 2 |
| 3 | 2 | 3 |
| 4 | 2 | 3 |
| 5 | 3 | 3 |
| 6 | 3 | 3 |
| 7 | 4 | 3 |
| 8 | 4 | 3 |
| 9 | 5 | 4 |
| 10 | 5 | 4 |
| 11 | 6 | 4 |
| 12 | 6 | 4 |
| 13 | 7 | 4 |
| 14 | 7 | 4 |
| 15 | 8 | 4 |
Colonizable positions
By default, only positions 4 to 12 can be colonized. With higher Astrophysics levels, you unlock:
- From level 4: positions 3 and 13
- From level 6: positions 2 and 14
- From level 8: positions 1 and 15
More details about planet size and positions are available on the Colonization page.
Expeditions
Astrophysics also increases the number of simultaneous Expeditions you can run and is required to send expeditions at all.
For strategy and recommendations on expedition fleets, see the Expeditions page.
Tips
- Prioritize Astrophysics if you want to expand quickly with multiple colonies.
- Combine Astrophysics with a good economy on your main planet to support new colonies.
- Unlocking more expedition slots is one of the best long-term sources of extra resources, ships and Dark Matter.
