A small team of astronomers at Université Côte d'Azur, Observatoire de la Côte d'Azur, working with a colleague from MCCE, Observatoire de Paris, Sorbonne Université, has found more evidence that the moon has an inner ...
Approximately 1,800 miles beneath our feet, swirling liquid iron in the Earth's outer core generates our planet's protective magnetic field. This magnetic field is invisible but is vital for life on Earth's surface because ...

(Phys.org)—Like the solar system's telluric planets, including Earth itself, the moon's internal structure is composed of geoochemically distinct mantle, crust and core layers. The core is mostly iron; much of our understanding ...
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 ...

It is widely accepted that the Earth's inner core formed about a billion years ago when a solid, super-hot iron nugget spontaneously began to crystallize inside a 4,200-mile-wide ball of liquid metal at the planet's center.

Along with its aesthetic function of helping create the glorious Aurora Borealis, or Northern Lights, the powerful magnetic field surrounding our planet has a fairly important practical value as well: It makes life possible.
