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

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

TRAPPIST-1 looks small and calm from Earth. Up close, it is anything but. The cool red star about 40 light-years away erupts with bursts of energy many times each day, sending radiation racing across ...

Sunspot AR3229 erupted with an X2-class solar flare. NASA's Solar Dynamics Observatory captured the fireworks in multiple ...

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

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 ...

In the span of two days last week, the sun released two strong solar flares — meaning the solar system experienced its most powerful explosions which can cause some communications blackouts on Earth, ...

A high-magnitude solar flare erupted from a new sunspot on the sun’s surface, which caused a disruption of radio signals across Earth’s Eastern Hemisphere on Tuesday. Classified as an X2.7 solar flare ...

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 high-powered solar flare erupted from the sun last week, causing a major radio blackout in Europe and Asia. The eruption happened at 3:25 a.m., meaning that the sun wasn't in the Texas sky at the ...
