Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...

Scientists have discovered yet another layer deep inside the core of the Earth, a new study suggests. "Traditionally we've been taught the Earth has four main layers: the crust, the mantle, the outer ...

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

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

The research into what lies deep, deep beneath our feet has yielded precious few details over the past few decades. We all grew up learning that we live on the Earth's crust, which is just a thin ...

It’s time to rewrite science textbooks. In a study, scientists claim to have discovered another layer in the Earth’s core. For many years, it has been widely believed that the Earth has four layers: ...

You may have been taught in school that the Earth is composed of layers, broadly separated into a rocky crust and mantle, outside of a liquid outer core and a small, solid iron inner core. It turns ...

While this new layer is difficult to observe, its existence may point to an unknown, dramatic event in Earth's history. Investigating the structure of the inner core can help us understand more about ...
