행성 X를 찾아서

No — an empty result can mean the sector is truly empty or that it contains Planet X; both surveys and targets treat the Planet X sector as appearing empty (page 9).

You must select the sector you think contains Planet X and also identify the objects located in the two adjacent sectors; you only succeed if both the sector and the two adjacent objects are correct (page 10).

You have two target tokens and must spend one each time you target a sector; after both are used you can no longer target, and a target reveals either the object in that sector or that the sector appears empty (page 9).

No — each research topic gives one private logic rule and there’s no reason to select the same topic again, and you are not allowed to take Research twice in a row (page 10).

After you advance your pawn you rotate the earth board clockwise toward the pawn farthest back, pausing when the arrow reaches any conference or theory icon to resolve that phase (conferences revealed only the first time an icon is reached); theory submission happens when the board hits a theory icon and peer review occurs when theories reach the inner space (pages 13–15).

If a theory is correct the object in that sector becomes confirmed and correct theory tokens remain for end‑game scoring; if a theory is incorrect it is removed and the submitting player advances their pawn one sector as a penalty (page 15), and once a sector’s object is confirmed no new theories may be placed there (page 14).
