Scientists develop a forecasting system that predicts high-risk windows and regions for solar superflares, using 50 years of X-ray data and machine learning techniques.

Scientists have proposed a surprising connection between solar flares and earthquakes. When solar activity disturbs the ...

Researchers have proposed that changes in Earth's ionosphere could trigger electrical forces that nudge fragile areas of the crust into creating an earthquake.

A 40-year study shows the Sun’s internal structure subtly shifts between quiet cycles, offering clues to future solar ...

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 ...

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

A strong solar flare peaked just after 9 a.m. Tuesday, but what does that mean? Can it be seen from Earth?Tuesday's solar flare was not the first this year or even this month. Here is more information ...
