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

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

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

Researchers followed a single solar hotspot for 3 months as it unleashed nearly 1,000 flares, revealing insights about our Sun's fury.

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 ...

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 ...

While the Sun’s solar flares strongly correlate with sunspots, observations of more than 14,000 other stars show this is not generally the case.

OVRO-LWA radio data contrasts a quiet day (Sept. 29, 2025) with the hours after the X1.7-class flare recorded at 2:35 ET on Nov. 9. The type III radio bursts, shown in the radio dynamic spectrum ...

Complex magnetic fields in the Sun's atmosphere help heat it to multi-million degree temperatures and create explosive events such as solar flares that affect us here on Earth.

With the Sun still in an active phase there could be more spectacular Northern light displays in the year ahead.

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 ...

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 ...
