A study on past reversals of Earth’s magnetic field has found that a rapid shift occurred within two centuries — such an event in future would increase our exposure to the Sun’s radiation that may ...

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 ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European ...

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...

Earth’s magnetic north pole has shifted toward Russia, prompting updates to GPS and navigation systems worldwide. Scientists track this invisible movement to keep technology accurate.

We can learn a lot from studying the rings inside trees. The science of tree-ring analysis is called dendrochronology, and ...

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 ...

Our planet's invisible shield is changing in ways that scientists are only beginning to understand. Over the past two hundred ...

The sun is on the verge of a significant event: a magnetic field reversal. What causes this switch in polarity, and is it dangerous for anything on Earth? Let's take a deep dive into the phenomenon of ...
