Australian scientists discovered a doughnut-shaped region in Earth's outer core, 2,900 km beneath the surface, contributing to the planet's magnetic field.

Scientists at the Australian National University discovered a doughnut-shaped region in Earth's outer core, 2,900 km beneath the surface. This region, parallel to the equator, has unique properties contributing to the planet's magnetic field, which protects life from solar radiation. The discovery, made using seismic waves from large earthquakes, reveals the presence of lighter chemical elements in the doughnut-shaped area, shedding light on Earth's magnetic field dynamics and core composition.
