The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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 ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life ...

The geomagnetic field, generated by the convecting motions of Earth’s liquid outer core, is a fundamental facet of our planet’s evolution. Its long‐term behaviour is recorded in rocks through the ...

Geomagnetic storms are capable of sparking beautiful displays of the Northern Lights across our night sky. However, there is a potential danger behind that beauty, especially now, with solar activity ...

In the South Atlantic, stretching from Chile to South Africa, there’s a wide span where the Earth’s magnetic field isn’t quite in line with the rest. Here, at what’s called the South Atlantic Anomaly, ...

Geophysicists studied the activity of high energy electrons and clarified the unexpected protective role of the geomagnetic field surrounding the Earth. Tohoku University geophysicist Yuto Katoh led a ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. According to a press release by Tel Aviv University, an ...

A solar cycle is a roughly 11-year periodic change in the Sun characterized by variations in the number and intensity of sunspots, as well as a flipping of its magnetic poles.
