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.

As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching 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 ...

The polar dance that caused snow to fall across the South in January has been studied for decades, but scientists still hope ...

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 ...

Here, the polar night lasts 106 days from October 30 ... This appearance of light is due to the refraction of sunlight through Earth's atmosphere, meaning it can produce hues of pink, red, orange ...

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 ...
