Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

Something massive is happening beneath your feet right now, and most people have absolutely no idea. Earth's magnetic field, the invisible force that protects all life on this planet and guides ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

Launched to Mars in November, NASA’s ESCAPADE probes — operated by UC Berkeley’s Space Sciences Lab — are now testing their ...

New research reveals that migrating moths rely on both visual signals and Earth’s magnetic field to guide their nighttime ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

A weak spot in the Earth's magnetic field is growing over the South Atlantic Ocean, according to more than a decade's worth of satellite data collected by scientists. The magnetic field surrounding ...

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...
