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 ...

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 ...

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 ...

Most planets have a magnetic field, like Earth, but with different strength or structure. It shields the planet from the energetic particles of the solar wind. The origin of the magnetic field is ...

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 ...

The breakthrough was made possible through the use of NASA’s Magnetospheric Multiscale (MMS) mission, which involves four identical spacecraft flying in a precise pyramid-like formation. This ...
