Aurora Setting the Stage for Polar Lights
The piece explains two key ingredients for auroras: Earth’s magnetic field and the Sun’s magnetic influence. It describes the Earth’s liquid iron core generating a magnetic field, how the field forms a protective bubble, and how solar storms trigger auroras seen from space and on Earth. It notes other planets also have similar displays.
