WebJun 10, 2024 · An article suggests the natural light show starts when disturbances on the sun pull on Earth's magnetic field, creating cosmic waves that launch electrons into the atmosphere to form the aurora. WebOct 30, 2024 · Nearly all of Earth’s geomagnetic field originates in the fluid outer core. Like boiling water on a stove, convective forces (which move heat from one place to another, usually through air or water) constantly churn the molten metals, which also swirl in whirlpools driven by Earth’s rotation.
