Earth's magnetic field and oxygen levels are inextricably linked, new research suggests. The strength of the geomagnetic field has gone up in lockstep with the percentage of oxygen in Earth's ...

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

As with any such correlation, one has to entertain the notion that said correlation might be spurious or indirectly related before assuming a strong causal link. Here it is for example known already ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

Long before life thrived in Earth’s oceans, the planet’s magnetic field became disorganized. Deep within the ancient rocks of Morocco, scientists have recovered one of the clearest records of that ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

Rosie is a freelance writer living in London. She has covered everything from ancient Egyptian temples to exciting medical breakthroughs, but she particularly enjoys writing about wildlife, ...

Life on Earth may exist thanks to a brief faltering in our planet's protective magnetic field shell, scientists have found. A bizarre drop in the strength of the magnetic field has been found to have ...

These rocks offer evidence that Earth had a strong magnetic field 3.7 billion years ago, but scientists aren't sure where that field could've come from. When you purchase through links on our site, we ...

As Earth’s magnetic field has risen, so have the conditions that helped complex life to thrive — a discovery that could aid the search for life on distant planets. The strength of Earth’s magnetic ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...
