“Named for the Roman goddess of dawn, the aurora is a captivating display of light in the night sky. The aurora borealis — also called the northern lights — occur at the northern pole. Occasionally, space weather interacting with Earth can cause auroras to extend even further away from the poles. These colorful lights are constantly changing shape and intensity, from dim and scattered to bright enough to read by. The dancing lights of the aurora provide spectacular views from the ground.
The Sun continuously produces a solar wind, made of charged particles that flow outward into the solar system. When the solar wind reaches Earth’s magnetic field, it can cause magnetic reconnection, an explosive process that allows charged particles from space to accelerate into the atmosphere.
Earth’s tear-shaped magnetic field — called the magnetosphere — continuously oscillates and responds to the changing intensity of the solar wind. The solar wind particles funnel around to the long tail of the magnetosphere, where they become trapped. When magnetic reconnection occurs, the particles are accelerated toward Earth’s poles. Along the way, particles can collide with atoms and molecules in Earth’s upper atmosphere, an interaction that provides the atoms with extra energy which is released as a burst of light. These interactions continue at lower and lower altitudes until all the incoming energy is lost. When we see the glowing aurora, we are watching a billion individual collisions, lighting up the magnetic field lines of Earth.”
