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 ...

X1.9-rated solar flare erupted from sunspot 4341 on January 18, causing R-3 radio blackouts.

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

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 ...

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

Largest solar radiation storm in more than 20 years could trigger auroras on Earth - A solar radiation storm this large has ...

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.

Research by university scientists suggests that solar flares may be far hotter than previously believed, offering new insights into the Sun’s behavior. The findings, recently published in the ...

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 ...

A trio of solar flares, similar to the one pictured from 2012, erupted from the sun this week, disrupting communications on Earth. File Photo courtesy of NASA Nov. 5 (UPI) --A moderate solar flare ...

After weeks of reduced activity, the sun erupted with three powerful flares on a single day. That could send solar flares toward Earth, impacting electronics and making it possible to view the ...

The sun is not only our closest stellar neighbor, it's also the star we understand the most. As we've observed it over the centuries, we've learned that the sun is not an immortal constant. It goes ...
