"We believe that the mechanism that 'turns on' these gigantic radio emissions is linked to the formation process of galaxy ...
The magnetic barrier that protects Earthlings from radiation almost collapsed some 565 million years ago. Here’s what saved it.
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, ...

Who knew that magnetic fields could be so useful? Astronomers are able to use magnetic fields to map our environment within the Milky Way using a technique called Faraday rotation. It works like this.
At the right point of the orbit and stellar cycle, the star’s chromosphere brightens.
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 ...

A team of researchers used tiny imperfections on a diamond lattice to successfully measure Earth’s magnetic field. The quantum device, called OSCAR-QUBE, measures just 10 centimeters (3.9 inches) on ...
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 ...
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 ...
