For years, NASA has monitored a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the ...

NASA detects first “magnetic switchback” near Earth: an energetic change in your space shield that reveals new solar risks.

Scientists studying Earth's magnetic field have discovered that its electric heartbeat flows in the opposite direction from what long-standing models predict. Earth is surrounded by a vast magnetic ...

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

Geologists discovered ancient rocks in Greenland that preserve the oldest known traces of Earth’s early magnetic field.

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

A growing weak spot in the magnetic field surrounding the Earth could lead to satellite malfunction and even cause them to undergo full blackouts, scientists warned in a new study. The Earth’s complex ...

They observed that the structure of tiny magnetic fields generated by the rotating electrons indicates that the organisms ...

Space is full of radiation. So much radiation, in fact, that the only thing standing between us and our planet being bathed in radioactive energy from the Sun is the Earth's magnetic field. And this ...

When we think about the Earth’s magnetic field, we often associate it with compasses and navigation. However, did you know that our planet’s magnetic field has a rich history of change, including ...

The north magnetic pole’s observed locations from 1831–2007 are yellow squares. Modeled pole locations from 1590–2025 are circles progressing from blue to yellow. Credit: National Centers for ...
