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

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

Solar flares have an enormous impact on the wider Solar System. These sudden releases of energy can cause geomagnetic storms on Earth and radio blackouts too, like the one that's happened in the last ...

“This is the longest continuous series of images ever created for a single active region: It’s a milestone in solar physics,” ...

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 ...

A rare blast from the sun has just pushed radiation in Earth’s atmosphere to levels not seen in nearly two decades, briefly turning the sky itself into a harsher place for high‑altitude flyers and ...

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

The sun is not a static, tranquil sphere of gas, but an active, turbulent star with magnetic fields that twist and snap in powerful eruptions. Among the most striking and energetic of these eruptions ...

Cryptocurrency investors face an unusual danger lurking 93 million miles away. Solar flares, massive bursts of energy from the sun’s surface, can interfere with the digital infrastructure that keeps ...

Solar flares can be many times the size of Earth and can damage things like satellites. A new study suggests that eruptions from the sun can be even hotter than researchers thought. Solar flares are ...
