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.

NASA’s BioSentinel Studies Solar Radiation as Earth Watches Aurora

In May 2024, a geomagnetic storm hit Earth, sending auroras across the planet’s skies in a once-in-a-generation light display. These dazzling sights are possible because of the interaction of coronal mass ejections – explosions of plasma and magnetic field from the Sun – with Earth’s magnetic field, which protects us from the radiation the Sun […]
