By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

The Sun’s most violent flares are turning out to be even more extreme than I, or many solar physicists, had imagined. By ...

The powerful belch of material ejected during a solar flare may be way hotter than scientists thought it was. A new mathematical analysis suggests that the engine driving solar flares is far more ...

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 ...

Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

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 sun has emitted a powerful solar flare that has the capability to interfere with technology on Earth. The explosive burst of radiation peaked on the evening of June 17, matching the intensity of ...

Researchers have identified a newly recognized type of extremely energetic particles located in the Sun’s upper atmosphere, revealing a phenomenon that had not been detected before. Solar scientists r ...

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 ...

Particles within solar flares may reach temperatures more than six times higher than scientists previously believed—offering an explanation to a long-standing astrophysical puzzle about the Sun. This ...
