For observers on Earth, the sun appears as a bright, familiar disk—but what we see is only half the story. Like the moon, one ...

Scientists have found a way to identify magnetic fields on the far side of the sun, a region that cannot be seen from Earth.

This study focused on regions that remain active for longer periods, where the strong magnetic field takes at least a month to weaken. According to NASA, the solar cycle is a natural process of the ...

Researchers using NASA’s SOFIA airborne telescope have found that magnetic fields are trapping the material that feeds the supermassive black hole in the galaxy Cygnus A. Collimated jets provide ...

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The ...

A new model contradicts previous theories that the sun's magnetic field originates deep inside its interior. Deep origin theories could not explain rotation patterns of the sun's gas near its surface ...

Aurora activity is easing after a strong weekend, but northern lights may still be visible tonight in high-latitude regions ...

Scientists have found that extreme solar activity drastically compresses the magnetosphere and modifies the composition of ions in near-Earth space. They are now looking to model how these changes ...

For the first time, scientists have mapped the magnetic polarity of active regions on the Sun’s far side without direct observation, using helioseismology to interpret sound waves traveling through ...
