If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely have little atmosphere to speak of. Life (at least of the human variety) ...

NASA's EZIE will study auroral electrojets, powerful electrical currents in Earth's atmosphere. This will improve space ...

Did you know that Earth’s magnetic field plays a significant role in shaping global weather patterns? This invisible shield not only protects us from solar radiation but also influences the movement ...

Geomagnetic excursions are short-lived, and involve temporary changes to the Earth’s magnetic field lasting anywhere from a few hundred to a few thousand years. The most recent recorded ...

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from ...

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from solar ...

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 ...

But it also opens new questions about how changes in the core could affect the length of our 24-hour day, Earth’s magnetic field and more. “After decades of research and debates, we are coming ...
