Unveiling Earth's Mysterious Inner Core: Liquid Iron Swirls and Complex Texture

Seismologists from the University of Utah have discovered that Earth's inner core is not a homogenous mass but rather a complex tapestry of different fabrics. Using seismic data from earthquakes and CTBTO's sensing instruments, the researchers found that the inner core initially grew rapidly, slowed down over time, and may contain trapped liquid iron. This new understanding provides insights into Earth's formation, evolution, and the creation of its protective magnetic field.
