A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells the ...

It took 250 years for the Laschamps reversal to take place and it stayed in the unusual orientation for about 440 years. At most, Earth's magnetic field may have remained at 25 percent of its current ...

leading to its reversal every 11 years. The solar cycle is crucial for understanding space phenomena, such as solar flares and coronal mass ejections, which can affect communications and electrical ...

For industries reliant on magnetic fields, such as aviation ... they have occurred periodically throughout Earth’s history—the last reversal took place around 780,000 years ago. Scientists are not yet ...

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.

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.

Understanding the Mystique of Magnetic Pole Shifts Magnetic pole shifts, a subject shrouded in both fascination and fear, ...

The Sun is preparing for a major event: the reversal of its magnetic field. This phenomenon marks a turning point in the solar cycle, signaling the transition from solar maximum to solar minimum.

as a weakened magnetic field would offer less protection against space weather. While life on Earth has weathered multiple magnetic reversals over more than 100 million years, “we’ve never ...
