Scientists at the Swiss federal technology institute ETH Zurich have reconstructed the history of the Earth's magnetic field.

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other ...

Researchers are on firmer ground when it comes to the physiological impacts of increased UV radiation. With the weakened ...

For more than 100 years, scientists have puzzled over whether the Earth’s magnetic field had already been generated stably ...

Scientists have long known that Earth’s magnetic field has not been a constant shield. Now, new interdisciplinary research—recently published in Science Advances shows that a major geomagnetic event, ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar ...

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 ...

Earth's internal magnetism, called the magnetosphere, generates a comet-shaped field around the surface of the planet that provides protection from harmful solar and cosmic particle radiation, as ...

Whilst the magnetic field strength appears to have remained relatively constant, the solar wind is known to have been significantly stronger in the past. This suggests that the protection of Earth ...

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

In 2013, the ESA launched three Swarm satellites for a mission to help decode how Earth’s magnetic field is generated by precisely measuring the radiofrequency signals coming from the planet’s ...
