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

The sun emitted another powerful solar flare Tuesday nearly one week after separate flares set in motion a severe solar storm that disrupted some technology and produced some mesmerizing northern ...

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 ...

Solar flares, the sudden bursts of radiation that erupt from the Sun’s atmosphere, have become a topic of intense scrutiny for scientists. The potential of these flares to disrupt power grids and ...

Newly emerged sunspot region AR3663 is already making a name for itself, firing off not one but two powerful solar flares within just six hours of each other. The first eruption occurred last night ...

Considered our solar system's largest explosive events, solar flares can sometimes be as strong as a billion hydrogen bombs. Those with enough energy output to rank as an X-class have the potential to ...

A recent CU Boulder study suggests that confined flares are more efficient at heating plasma and producing ionizing radiation than comparable eruptive flares While many studies have compared the ...

On December 8, 2025, the Sun unleashed a powerful solar flare, an event that captivated the attention of scientists and space enthusiasts alike. This flare, classified as an X1.1, marks one of the ...

Scientists have captured an exceptionally rare, high-resolution view of an active region that produced two powerful X-class solar flares—an achievement rarely possible from Earth. Using the GREGOR ...

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 ...
