Earth's Molten Iron Core Unexpectedly Reversed Direction Beneath the Pacific

Scientists have discovered that a large flow of molten material deep beneath the Pacific Ocean unexpectedly changed direction. This dramatic shift in Earth's molten iron core, which is responsible for generating the planet's magnetic field, was traced using data from ESA satellites. The event challenges previous understandings of stable westward circulation in the outer core and raises questions about the dynamic connections within Earth's deepest layers.
