The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years.

The magnetic fields that formed in the very early stages of the universe may have been billions of times weaker than a small ...

Illustration of the global coronal magnetic field as the sun rotates. The background is the solar corona observed in extreme-ultraviolet waveband, with global coronal magnetic field maps measured ...

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.

New research suggests that the largest magnetic fields in the universe originated through some exotic mechanism that absolutely soaked the early cosmos.

The Earth's magnetic field surrounds our planet like an invisible force field—protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this ...

You usually can't hear or see the Earth's magnetic field, but researchers in Denmark found a clever way to capture its "groans." ...

When Our Magnetic Field Flips By Rick Groleau Posted 11.18.03 NOVA Every so often—every 250,000 years on average—the Earth's magnetic poles reverse polarity. If such a reversal happened today ...

Earth's magnetic north pole keeps moving. In the past few years, it has moved so much that the National Oceanic and Atmospheric Administration issued an early update to its World Magnetic Model ...

During solar minimum, the sun's magnetic field is close to a dipole, with one north pole and one south pole, similar to Earth's magnetic field.
