A 42,000-year-old tree reveals Earth’s last magnetic pole flip, exposing the planet to deadly radiation. Scientists warn a ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this epic upheaval, ...

Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps moving. Here’s what to know.

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not ...

With the right preparations and technological solutions in place, aviation would continue to operate safely, even during a ...

NASA via Rawpixel For decades, Earth’s magnetic north pole has been slowly ... Geophysicists have long speculated that the weakening of the magnetic field could signal a potential geomagnetic reversal ...

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 ...

Earth’s magnetic field has behaved even more dramatically in the past, with the magnetosphere weakening so much that its polarity reversed. This flips the magnetic north and south poles ...

No one knows why, but Beggan said it’s probably linked to some pockets of the magnetic field getting stronger and others weakening. He said the overall strength of the Earth’s magnetic field ...
