Earth’s ‘solid’ inner core may contain both mushy and hard iron
Scientists have discovered a heterogeneous structure in the Earth's inner core, with adjacent regions of hard, soft, and liquid iron alloys. This finding challenges traditional models of the planet's magnetic field generation and provides new insights into the dynamics at the boundary between the inner and outer core.
