Geologists at the University of Illinois have confirmed the discovery of Earth’s inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core. “For many years, we have been like blind men touching different parts of an elephant,” said geologist Xiaodong Song. “Now, for the first time, we have a sense of the entire elephant, and see what the inner core of Earth really looks like.” (source: news.uiuc.edu)
