Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

Dark matter having a small electric charge would presumably generate a magnetic-field variation on Earth’s surface, but observations find no such signal. Dark matter can’t have a typical electric ...

Hundreds of millions of years ago, Earth’s magnetic field behaved in a way that has long baffled scientists, showing wild and seemingly chaotic shifts unlike anything seen before or since. A new study ...

A weak spot in the Earth’s protective magnetic field has nearly doubled in surface area since 2014. And it’s still growing. The South Atlantic Anomaly now stretches across all of South America nearly ...

Learn how Earth's magnetic field may influence how we age and how its effects on mitochondria could reveal new therapies for Parkinson's and Alzheimer's. Earth’s magnetic field is deeply ingrained in ...

Nearly two centuries after Faraday’s failed attempts, scientists have demonstrated that Earth's continuous spin can directly generate electrical current. Back in 1832, the celebrated British physicist ...
