Iron is one of the main elements found in the Earth's inner core, which is characterized by extremely high temperatures and pressures. Determining how iron behaves in these extreme conditions could ...

A surprising reversal in molten iron flow beneath the Pacific is giving scientists a sharper view of how Earth’s magnetic ...

Cubic core: what is the crystal structure of iron at the centre of the Earth? (Courtesy: shutterstock/Johan Swanepoel) A long-standing debate about the structure of solid iron at the centre of the ...

Forbes contributors publish independent expert analyses and insights. The iron jet is moving at about 50 km per year, orders of magnitude faster than plates move and much faster than anything ...

Researchers led by the University of Maryland have found that the sun's magnetic field is the reason behind the large size of Mercury’s iron core. The study has been published in Progress in Earth and ...

A model of iron atoms on the move in Earth's inner core. The model demonstrates how iron atoms are expected to move about in the Earth’s inner core over 10 picoseconds, or 10 trillionths of a second. ...

It’s one of nature’s topsy-turvy tricks that the deep interior of Earth is as hot as the Sun’s surface. The sphere of iron that resides there is also under extreme pressure: about 360 million times ...

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet's core and crust). For decades, scientists argued that hit-and-run ...

One of the biggest arguments about the inner solar system among astronomers and scientists is why exactly Mercury has such a massive iron core. The prevailing theory is that collisions with other ...
