Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Imagine a sphere of pitted iron, grey and imperfect like a large cannonball. Think of this dense, heavy ball as the total mass of each day’s serious reported news, the iron core of information that is ...

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 ...

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 ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Mercury’s disproportionately massive core may be the result of the Sun’s powerful magnetic influence rather than the consequence of a cataclysmic collision with another body in the ancient past, ...

Earth's inner core may have paused and reversed its spin, a new study suggests. Earthquakes and nuclear blasts can send seismic waves through the mysterious solid-iron core. Those waves hint that the ...

Induction cook tops are among the most efficient ways of cooking in the home that are commercially available to the average person. Since the cook surface uses magnetic fields to generate heat in the ...

Our planet’s interior is complex and has many layers. There are many unsolved mysteries about the formation and structure of these layers, but new research is providing some clues about how Earth’s ...

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 have used a diamond anvil cell to squeeze iron at pressures as high as 3 million times that felt at sea level to recreate conditions at the center of Earth. The findings could refine ...
