The gigantic coronal hole is blasting high-speed solar wind toward Earth, potentially igniting vibrant auroras and minor geomagnetic activity on Jan. 31.

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

A NEW Chinese fusion facility may be where the world’s first “artificial sun” is born – but could also be used to develop deadly nuclear weapons. Experts have said a huge ...

and that the energy of the earth comes mainly from the sun, he began to study what Sir William Herschel had called “the great secret” of the maintenance of solar heat. In 1841, before the ...

Cosmic rays coming from outside the Solar System bring these particles closer to the Sun, where they experience changes ...

A new study finds that the rate of ocean warming has more than quadrupled over the past 40 years—and pinpoints why.

The sun has a lot more pressure than Earth's reactors ... which is the point at which nuclear fusion creates its own energy and sustains its own reaction, but the new record is a step towards ...

Intense solar flares—sudden bursts of electromagnetic radiation from the Sun—can shoot out hazardous levels of energy strong enough to reach Earth’s atmosphere. Predicting solar flares, ...

Researchers at the Chinese Academy of Sciences (CAS) aim to safely replicate the sun’s nuclear fusion processes here on Earth, thereby solving global energy crises and facilitating exploration ...

Such superflares release more energy than a trillion hydrogen bombs ... 2024 — Like the Earth, the Sun likely has swirling polar vortices, according to new research. But unlike on Earth, the ...
