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

Something massive is happening beneath your feet right now, and most people have absolutely no idea. Earth's magnetic field, ...

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

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

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

Past magnetic-field data helps us understand the "geodynamo" — the engine that generates our planet's protective magnetic field. This field is generated by liquid iron slowly moving around the ...

Add Yahoo as a preferred source to see more of our stories on Google. Protective force fields exist and you’re already living inside one. About 1,800 miles beneath the ground you’ll reach the border ...

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 ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Earth’s magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...
