Magnetic deposits laid down during the Ediacaran Period, 630 million years ago to 541 million years ago, are not inexplicable ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today. A new study, led by the University ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

The Earth’s magnetic field has flipped 183 times over 83 million years, and a weakening field raises the risk of solar ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. Now you can actually 'hear' this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

A giant dent in Earth's magnetic field is continuing to expand, according to the latest data from a trio of satellites monitoring our world. It's called the South Atlantic Anomaly, stretching across ...
