Beneath the question of life beyond Earth lies a quieter question: what keeps a world breathable? New research proposes that the answer is not written in the sky but forged in the deep interior of planets, where oxygen's chemical relatives — elements like sulfur and iron — may be locked away in planetary mantles, stabilizing the atmospheric oxygen that complex life requires. This finding asks us to reconsider habitability not as a surface condition but as a whole-planet phenomenon, one shaped as much by hidden geology as by sunlight and water.
