A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, continues to attract focused attention from NASA researchers. This region ...

As the field weakened to only 5 percent of its current strength the reversal process allowed a surpluss of cosmic rays to pass into Earth's atmosphere.

From the smallest bacteria to migratory birds and large mammals, it turns out that sensing the Earth’s magnetic field is far ...

About 41,000 years ago, Earth’s magnetic field briefly flipped in what is known as the Laschamp event. Now, a group of scientists using data from the European Space Agency’s (ESA) Swarm ...

This summer, the European Space Agency published data that suggested that the Earth's magnetic field could flip -- as in, the magnetic north pole becomes the magnetic south pole -- in 'a few ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic field.

Berkeley – A chance observation of high-energy electrons emanating from a tiny region of space where the sun and Earth’s magnetic fields intertwine provides the first solid evidence that a ...

The strength of Earth's magnetic field has correlated with fluctuations in atmospheric oxygen for hundreds of millions of years, according to a newly released analysis by NASA scientists ...

Monarch butterflies use Earth’s magnetic field as a compass. Cold winter temperatures reverse their direction for spring ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this upheaval as an unnerving clatter interpreted from information collected by the European ...
