3,200 miles beneath Earth's surface lies the inner core, a ball-shaped mass of mostly iron that is responsible for Earth's magnetic field. In the 1950's, researchers suggested the inner core was solid, in contrast to the ...

A team of scientists at Arizona State University has proposed that the large blobs of material in Earth's mantle (the large low-shear velocity provinces, LLSVPs) may be left over pieces of Theia, a protoplanet theorized to ...
Diamond, like graphite, is a special form of carbon. Its cubic crystal structure and its strong chemical bonds give it its unique hardness. For thousands of years, it has also been sought after as both a tool and as a thing ...
