A major dip in the Earth’s magnetic field over the South Atlantic has been puzzling scientists for over a century. An international team of researchers analyzed data collected by the European Space ...

A stream of charged particles known as the solar wind flows from the Sun toward Earth. Here, it meets the Earth’s magnetic fields, which shield our planet like a giant umbrella. The Space Umbrella ...

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

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 ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Roughly 42,000 years ago, Earth’s magnetic field weakened dramatically during the Laschamps geomagnetic excursion, allowing more cosmic radiation to reach the atmosphere. In a peer‑reviewed study of ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...
