"We believe that the mechanism that 'turns on' these gigantic radio emissions is linked to the formation process of galaxy ...

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 ...

There is an invisible force protecting us, keeping our atmosphere in place. Without it, life on Earth would be over very ...

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 ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

Pigeons and other birds can do it. So can sea turtles and spiny lobsters, moths and mole rats, gray whales and big brown bats. Many members of the animal kingdom can detect the subtle undulations of ...
