"Unraveling the Mystery Behind Earth's Core's 8.5-Year Wobble Cycle"

Scientists from Wuhan University have proposed a new explanation for the mysterious 8.5-year wobble of Earth's inner core, suggesting it is misaligned by 0.17 degrees from the mantle's rotational axis. This finding, published in Nature Communications, challenges the conventional understanding of the core-mantle relationship and could provide insights into the Earth's geomagnetic phenomena. The research, which analyzed polar motion and length-of-day changes, may also help explain variations in the Earth's magnetic field over time.

"Unveiling the Earth's Core Rhythmic Shift Every 8.5 Years"

Chinese scientists have discovered that the Earth's inner core undergoes a periodic wobble around its rotational axis every 8.5 years, a phenomenon that could impact our understanding of the Earth's magnetic field and geophysical properties. This wobble, detected at a depth of approximately 1,800 miles, occurs due to a slight misalignment between the inner core and the mantle. The study, published in Nature Communications, highlights the complex interactions within Earth's core, which influence the planet's day length and magnetic protection against solar radiation.
