Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class ...

As this month's string of powerful X-class solar flares sparked brilliant auroras that lit up skies across an unusually wide ...

The sun has a bone to pick with Earth — and it’s not done yet. A colossal solar storm just zapped the daylight side of the planet, causing global blackouts and knocking out radio signals across Europe ...

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 ...

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 ...

Beautiful yet dangerous solar flares that erupt from the sun could be as hot as 180 million degrees Fahrenheit, researchers say. That's more than six times hotter than solar physicists previously ...

The M4.4 solar flare unleashed a coronal mass ejection (CME) into space — and Earth might just receive a glancing blow. Sunspot region 4168 is certainly making quite a name for itself! Earlier this ...

Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ultraviolet light before a solar flare, which could act as an early warning system ...

As the sun geared up to spit a powerful solar flare into space, NASA scientists snapped huge loops of plasma leaping from the sun's surface. These spectacular solar structures, known as coronal loops, ...

Solar flares are intense bursts of light and particles from the sun. While they can pose hazards for things like satellites, these flares are also beautiful, dramatic and incredibly hot. NPR's Nell ...
