The Sun's magnetic field impacts the movement of plasma on the sun's surface, but it does not actually impact the amount of heat the sun emits. Solar flares, for example, are huge explosions that ...

Long-term satellite measurements show that Earth’s magnetic field is changing faster and more unevenly than expected, driven ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies above the planet, stretching out between South America and southwest ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are directly influencing our planet's magnetic field in ways we're only beginning ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

Detectable changes in the Earth's magnetic field can be observed a few days before major earthquakes in California. "It's a modest signal," Dan Schneider, director of QuakeFinder, an earthquake ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a given location.
