Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory puts that timeline at roughly 5 to 10 billion years in galaxies. Yet ...

Solar magnetism is a fundamental driver of dynamic phenomena on the Sun, manifesting in cyclic variations such as sunspot activity, flares, and coronal mass ejections. Central to this process is the ...

The universe is highly magnetic, with everything from stars to planets to galaxies producing their own magnetic fields. Astrophysicists have long puzzled over these surprisingly strong and long-lived ...

For decades, scientists have pondered the mystery of the moon's ancient magnetism. Based on analyses of lunar samples, its now-deceased magnetic field may have been active for more than 1.5 billion ...

Lower panel shows a collapsing plasma cloud with uniform magnetic field (red).Top Right: Compression alone amplifies the field. Bottom Right: Collapse-driven turbulence accelerates dynamo ...

More than 50 years ago, NASA landed humans on the Moon — and we brought a piece of it back with us to Earth. That 22 kilograms of rock and dust collected by the Apollo astronauts transformed our ...
