Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate than a simple metal ball. Instead of a single solid sphere, the inner core ...

Earth’s core is a strange, strange place. For decades, scientists have suspected that, like Matryoshka stacking dolls, there may be an additional hidden layer within our planet’s solid iron and nickel ...

One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that suggests ...

Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. The study may help explain a weird area in the outer core that has long puzzled scientists. One expert said ...

Back in my day, there were only four layers of Earth: the crust, mantle, liquid outer core and solid inner core. Now, scientists have revealed a new, distinct layer within our planet’s inner core, ...

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 ...
