The powerful belch of material ejected during a solar flare may be way hotter than scientists thought it was. A new mathematical analysis suggests that the engine driving solar flares is far more ...

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 ...

This reason is enough to delay the Artemis II mission further, says a Mexican nuclear physicist to the Starlust team.

Earlier this week, the number of visible sunspots on our home star fell to zero for the first time in 1,335 days. This ...

Researchers say a deadly earthquake in Japan and 2023’s most powerful solar flare occurring back-to-back can’t be a ...

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 ...

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 ...

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 ...

The National Solar Observatory on Mt. Haleakala recorded this high-resolution image of a solar flare on the sun. According to the observatory, the image is about four Earth-diameters on each side.

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 ...

“The definition of the solar maximum is when the sunspot number is at its highest,” Dr Rachel Howe, a solar physicist at the ...
