Astrophysics
Overview
Astrophysics enables colonisation of additional planets and unlocks expedition slots. Every 2 levels grants one additional colony slot. Every 3 levels grants one expedition slot. It is the most important research for account expansion.

Tips
Biggest Lever in Early Game
Going from 1 to 3 planets doubles your production. Astrophysics 3 is the highest-ROI investment after basic mines and drives.
1.75× Factor
Astrophysics uses a 1.75× cost factor instead of 2×, making it cheaper to level than most other research. Prioritise it.
Colony Position Matters
Choose cold outer slots for Deuterium production and larger inner planets (if available) for primary mines. Plan before colonising.
