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 ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening. Two of our best ways of measuring the cosmic expansion rate, the ...

Magnetic invisibility sounds simple in theory. Place the right materials around an object and magnetic fields flow around it as if nothing were there. Reality has been far messier. For nearly two ...

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Discover how magnetic levitation technology powers high-speed maglev trains, enabling frictionless travel and impressive ...

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 ...
