Researchers at Kyoto University have proposed a new physical model that explores how disturbances in the ionosphere may exert ...

Fired from a vast sunspot, the "coronal mass ejection" is expected to reach Earth on either Thursday or Friday this week.

A strong solar flare peaked just after 9 a.m. Tuesday. What does that mean?

What Are Solar Flares? Solar flares are explosive bursts of radiation resulting from the release of magnetic energy associated with sunspots. They occur when magnetic fields around sunspots become ...

NASA has reported a X4.2 solar flare, so what does it mean? We break down what a solar flare is and how it connects to the ...

The Sun is putting on quite a show right now. Earth-facing sunspot region 4366 has been erupting almost non-stop since it emerged on January 30, producing six X-class solar flares so far.

Just as avalanches on snowy mountains start with the movement of a small quantity of snow, the ESA-led Solar Orbiter ...

NASA captured powerful solar flares from Sun's active Region 4366, raising the possibility of auroras and brief radio disruptions on Earth.

For years, Charlotte Pearson and her colleagues at the University of Arizona Laboratory of Tree-Ring Research have used tree‐ring science to travel back in time, hoping that clues from the past will ...

New SwRI-led research connects circular flare ribbons, as observed with by Swedish 1-m Solar Telescope during the M4.7-class solar flare on May 3, 2023, with energy released by repeated bursts of ...

"This is one of the most exciting results from Solar Orbiter so far." ...

A major flare-up affected an aircraft’s data and control; the solution was so easy that it almost makes no sense.
