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 Sun has just unleashed an M5-class solar flare, a powerful burst of radiation that signals a clear uptick in solar activity as the current cycle heads toward its peak. While this event is not the ...

The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar ...

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 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 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 ...

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 ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. These processes follow the solar cycle, an 11-year cycle of increasing and decreasing activity on ...

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