Earth’s magnetic field seems steady and true — reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes. The magnetic North Pole is currently careening ...

ESA satellites detected a dramatic reversal in Earth’s molten core flow beneath the Pacific, revealing unexpected changes ...

The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity ...

The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA ...

Deep beneath the Pacific near the equator, Earth’s outer core now flows east instead of west. Dynamics deeper within our planet’s core may help explain the change and what to expect in the near future ...

Somewhere between us and the Sagittarius Arm, the Milky Way’s magnetic field quietly switches direction. A team of radio ...

If our planet flips and no one’s around to hear it, does it still make a sound? Scientists have managed to put a chilling soundtrack to the flipping of Earth’s magnetic field — and the result is ...

A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

The Milky Way’s magnetic field, the invisible scaffold that steers cosmic rays and shapes the gas between stars, has been ...

Astronomers have uncovered a strange magnetic “flip” hidden inside the Milky Way. Using a new radio telescope, researchers ...
