During a close approach to the Sun, the European Space Agency’s Solar Orbiter watched that tipping point unfold in unusually ...

Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter ...

The planet is experiencing the most powerful solar event since 2003—and it's bringing spectacular Northern Lights.

"This is one of the most exciting results from Solar Orbiter so far." ...

NASA researchers show that artificial intelligence can anticipate solar flare buildups by tracking subtle changes across the ...

Federal forecasters are warning that a powerful X-class solar flare could trigger strong radio blackouts and strain power ...

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 ...

Scientists watched a solar flare grow from tiny magnetic sparks into a violent plasma-raining avalanche on the Sun.

Solar Orbiter captured the most detailed view of a solar flare, observing the build-up of events that lead to the explosion.

An X-class solar flare has produced an Earth-directed coronal mass ejection, increasing solar activity and raising the likelihood of geomagnetic impacts within 24 hours.

F or all of its life-sustaining energy, the sun is pretty chaotic. Roiling plasma covers its surface along with fluidic snarls of magnetic fields that birth solar flares. These fiery outbursts occur ...
