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 ...

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

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.

This was the view as a multi-colored curtain of aurora formed to the south in my sky during the great display of Northern Lights on May 10, 2024. The Kp Index peaked at 8 this night bringing the ...

After weeks of reduced activity, the sun erupted with three powerful flares on a single day. That could send solar flares toward Earth, impacting electronics and making it possible to view the ...

Researchers led by Dr. Zhou Xinping from Yunnan Observatories of the Chinese Academy of Sciences and their collaborators have found solid evidence of coronal waves excited by flares.

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

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 ...
