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 ...
