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

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

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

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 ...

“It’s a milestone in solar physics,” said Ioannis Kontogiannis, a solar physicist at the Swiss Federal Institute of ...

What processes are responsible for heating solar flares and what dangers do they pose to Earth? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an ...

An international team of researchers tracked the active solar region using the Solar Orbiter spacecraft, a joint NASA and ...

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 ...

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 ...

Researchers have achieved a breakthrough in solar physics by providing the first direct evidence of small-scale torsional Alfvén waves in the sun's corona—elusive magnetic waves that scientists have ...

Solar physics investigates the complex processes occurring in our Sun – the nearest star and a prototypical example of stellar activity. Central to the discipline is an understanding of the Sun’s ...
