The surface of the Earth ... structure. A study, led by Australian National University geophysicist Joanne Stephenson, posits that the Earth’s inner core may, in fact, have two distinct layers.

Exposing the secret layers of the Earth’s core The inner core, a solid iron-nickel sphere encircled by a molten outer core, is located deep within the Earth. However, according to recent research, ...

This sample, which is more than six times longer than the previous core of mantle rock, has given us a glimpse into the composition of this mostly inaccessible layer of the Earth. You can read ...
