An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The elements emerge when ocean islands form.

You might think the Earth's largest gold reserves are locked up at Fort Knox. But Earth's core is rich with the precious metal - and it's slowly making its way up towards us.

Indeed, more than 99.999% of the Earth's gold is thought to be locked in the core, along with platinum, iridium, and ruthenium, other siderophile (iron-loving) elements.

It’s not much of a stretch to say that Earth’s inner structure, especially the innermost spherical core, has stupefied scientists for generations. It sits over 3,000 miles below the surface, smaller ...

Recently, scientists have discovered that the Earth's inner core thought to be in a solid state and also an unchanging sphere, may have undergone significant shape changes over the past 20 years.

Using earthquake data, Vidale and his colleagues have been working for years to unveil the mysteries of the inner core. In 2022, they published a paper describing what appeared to be a link between a ...

Earth’s inner core is surrounded by an outer core, and the interface between the two, around 5,100 kilometres below the planet’s surface, is a mysterious realm.

Earth’s inner core isn’t just slowing; it’s also shape-shifting, study finds A new study from USC scientists reveals Earth’s inner core is undergoing structural transformation.

Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really ...
