A series of three powerful flares and associated explosions of solar material out across the Solar System have set Earth squarely in the path of a "severe"-level geomagnetic storm. According to models ...

A vast, magnetically tangled sunspot has rotated into direct view of Earth, raising the prospect of powerful solar eruptions in the coming days. The active region is large enough to dwarf our planet ...

Solar storms are eruptions that release some of the energy stored in the sun's strong magnetic field. These can create intense, localized explosions called solar flares, or much more powerful and ...

A rapidly growing sunspot has fired off at least 18 M-class and three X-class flares in just 24 hours, including an intense X8.3 eruption.

(CNN) — For the first time, astronomers say they have spotted a giant explosion released by a star beyond our solar system. The eruption was similar in some ways to those unleashed by our sun, such as ...

Solar Orbiter has captured the clearest evidence yet that a solar flare grows through a cascading “magnetic avalanche.” Small, weak magnetic disturbances rapidly multiplied, triggering stronger and ...

An active region on the Sun, AR1515, has been putting on quite a show over the last 8 days, sending out all sorts of solar flares. Scientists were sure the huge sunspot was building up to produce an X ...
