Earth's inner core is an enduring mystery
The Earth’s inner core is a total mystery – here’s how we’re starting to solve it
Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth’s inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface. In fact, without it we’d be unlikely to even exist.
Scientists Uncover Mysterious Doughnut Structure in Earth’s Outer Core
Scientists at ANU have discovered a doughnut-shaped area in Earth's liquid outer core that could help explain mysteries about the planet's magnetic field, highlighting the need for ongoing multidisciplinary research in this area.
This process, known as the geodynamo, is driven by the convection currents in the outer core and the Earth's rotation.

Earth's inner core rotation has begun moving backwardsOne hypothesis, proposed in 2023, suggested that the inner core, which had once spun faster than Earth, was now spinning slower. At one point, the scientists reported, the core's rotation ...
A single rotation of our planet takes 24 hours ... which matches observations by astronomers and satellites. Earth’s inner core has been slowing down for 14 years. It comes just weeks after ...
Climate change affects the Earth's rotation spin making it wobble, which gradually results in increasingly longer days.
Scientists discovered a doughnut-shaped region in Earth's liquid core. It offers new insights into Earth's magnetic field.
These include tectonic plate movements, changes in the Earth's inner core rotation, and gravitational effects from the moon. However, human-caused climate change is now recognized as a significant ...
