Fifty light-years away, the James Webb Space Telescope has turned its gaze upon LHS 3844b — a world larger than Earth yet emptied of everything that makes Earth alive. In reading the infrared light bleeding off this scorched, airless rock, astronomers have found not a twin to our planet but a cousin to Mercury: geologically silent, atmospherically bare, and tidally frozen between fire and darkness. The deeper meaning lies not in what this world possesses, but in what its barrenness teaches us — for the technique used to read its surface may soon illuminate the character of countless other dist
