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

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 ...

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

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-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 ...

A powerful X2.7-class solar flare erupted from the sun early Tuesday, May 14, 2025, causing high-frequency radio blackouts across broad swathes of Europe, Asia, and the Middle East. Classified as an ...

New research from the University of St Andrews has proposed that particles in solar flares are 6.5 times hotter than previously thought. The research provides an unexpected solution to a 50-year-old ...

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 ...

A single patch on the Sun recently stayed hyperactive for 94 straight days, hurling flare after flare into space and setting ...

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 forecasting of solar flares is a rapidly evolving field that combines observational solar physics with the latest developments in machine learning and statistical modelling. Solar flares are ...
