From these indirect observations, scientists have calculated that the scorchingly hot inner core, with temperatures ...

Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even ...

The monumental finding suggests the Earth has five major layers instead of four, and offered new details scientists could use to help unlock some of the oldest mysteries about our planet and how ...

There is more to the Earth than what we can see on the surface. In fact, if you were able to hold the Earth in your hand and slice it in half, you'd see that it has multiple layers. But of course ...

The findings have implications for our understanding of how the core influences the other layers of the Earth.

By crushing minerals between diamonds, a new study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may ...

The Earth’s inner core is separated from the rest of the planet by its liquid outer core, so it rotates at a different pace and direction.

Scientists have long wondered what lies at the center of the Earth. New research is putting weight behind a theory that our home planet has a distinct ball of iron within its metallic core.
