Pigeons Rely on the Earth’s Magnetic Field to Navigate. Now, Researchers May Have Uncovered How They Do It
In the late 1800s, the French naturalist Camille Viguier proposed an idea that would be dismissed and forgotten for more than ...
Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in ...
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 ...
Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...
Satellite data reveal that a weak region in Earth's magnetic field has grown by an area roughly half the size of continental Europe in the last 10 years. A weak region in Earth's magnetic field has ...
The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole will shift over the next five years. Here's why it was changed. When you ...
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 ...
Simulations and satellite data reveal that Earth's magnetic field is more complex than scientists had thought. Scientists studying Earth's magnetic field have discovered that its electric heartbeat ...
