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 ...

The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA ...

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 ...

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 ...

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 ...
