Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

Earth’s magnetic field may affect cells in unexpected ways, according to experiments tracking lifespan, movement, and energy ...

Scientists have long known that migrating birds and homing pigeons navigate in part by sensing the Earth’s magnetic fields, especially at night or in overcast conditions when visual landmarks or ...

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 ...

Studying exoplanets has given astronomers insights into the characteristics that could help them find life beyond Earth. For ...

For as long as there's been life on Earth it's been shielded by our planet's magnetic field. And yet, we still don't know a lot about how this invisible protector has shaped our biology. A new study ...

A new study from researchers at the University of North Carolina at Chapel Hill provides the first empirical evidence that loggerhead sea turtles can learn and remember the unique magnetic signatures ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

The moon no longer has a global magnetic field, but lunar rocks and soils still contain records of ancient magnetism. Studying the magnetic minerals in these samples can help scientists understand how ...
