New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

Satellites observed a coronal mass ejection on Wednesday (Nov. 15), capturing a bright burst of super-hot plasma that warped the sun's magnetic field.

New research suggests that the largest magnetic fields in the universe originated through some exotic mechanism that absolutely soaked the early cosmos.

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a unifo… ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use ...

Illustration of the global coronal magnetic field as the sun rotates. The background is the solar corona observed in extreme-ultraviolet waveband, with global coronal magnetic field maps measured ...

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.

Astronomers have captured polarized light coming from the Milky Way’s central supermassive black hole, giving insight into its magnetic fields.

Instead of only measuring the strength of magnetic fields, the improved version can also determine their direction, which was previously not possible with purely optical magnetometers.
