We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit ...

Earth's inner core is dominated by iron, which can exist as a solid material in more than one crystallographic form. (This quality allows iron to combine with other elements to form alloys.) Iron's most stable form at room ...
