Recently, scientists found a ring-like figure within the spinning pool of molten metal in our planet's core. It is identified as a giant doughnut-shaped region within the outer core on par with the equator, where seismic waves move around 2 percent slower than the other parts of the core. 
Professor Hrvoje Tkalcic said that they don't know the thickness of the doughnut, but they estimate that it is about a few hundred kilometers beneath the core-mantle boundary.
The doughnut in the planet's core is said to comprise lighter chemicals like oxygen, hydrogen, silicon, sulfur, or carbon.
