From Earth, we only ever see half of the sun. The other half—the far side—is always hidden from view. But what happens there still matters. Powerful activity forming on the far side can rotate toward ...

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 ...

Researchers at the U.S. National Science Foundation's National Solar Observatory have developed a method to determine the magnetic polarity of active regions on the sun's far side using ...

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 ...

Stellar archaeologists have found “fossil” magnetic fields in dead stars called white dwarfs, giving clues to how our sun is ...

Acting as stellar archaeologists, scientists have found fossilized magnetism on long-dead white dwarf stars, which may help ...

Then, they can erupt dramatically, blasting charged particles into space and sometimes sparking solar storms near Earth. To ...

At more than one million degrees, the sun's atmosphere—the corona—is incredibly hot; but not everywhere. Time and again, huge ...

Scientists discover hidden "ghost plume" that is so powerful that it is physically warping the internal layers of the planet ...

Prominences are cool plasma structures extending several thousand kilometers in the Sun’s hot corona. Some persist for weeks.
