A new study published in Physics of the Earth and Planetary Interiors changes the long-standing consensus among scientists that the Earth’s inner core is a solid iron ball surrounded by a high-temperature molten outer core.

“The more we analyze it, the more we understand that it is not an iron ball. We are discovering a new hidden world.” He said To Live Science Gateway Jessica Irving, a seismologist at the University of Bristol, UK, who was involved in the research.
