= 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:

|}

== 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.
