5 Min Read NASA’s EZIE Launching to Study Magnetic Fingerprints of Earth’s Aurora High above Earth’s poles, intense electrical currents called electrojets flow through the upper atmosphere when auroras glow in the sky. These auroral electrojets push about a million amps of electrical charge around the poles every second. They can create some of [...]
