Aurora Borealis Caused by Explosions of Magnetic Energy NASA Study Says

Magnetic energy explosions 80,000 miles above the surface of the Earth result in the Aurora Borealis or Northern Lights witnessed in northern areas of the planet revealed NASA scientists studying the mysterious bright wave-like movements in the atmosphere.

Using a fleet of five NASA satellites designed to observe and record magnetic and electrical activity around Earth, the researchers found that the sudden changes were caused by magnetic reconnection, a common process that occurs throughout the universe when magnetic field lines stretched by the force of the solar wind suddenly snap into a new shape, like a rubber band that has been stretched too far, reported The Washington Post today.
