There appears to be more to Earth's inner core than previously thought. Researchers at the University of Illinois and Nanjing University in China have determined that there is a mystery material at our planet's inner core. The researchers say they founded a distinct inner-inner core in the Earth using seismic waves.

Xiaodong Song, a professor of geology at the University of Illinois, says in a statement, "Even though the inner core is small - smaller than the moon - it has some really interesting features. It may tell us about how our planet formed, its history, and other dynamic processes of the Earth. It shapes our understanding of what's going on deep inside the Earth."
