"Sunspots 4114 erupted with an X1.2-class solar flare. Minutes lates, sunspot AR4115 "erupted in quick succession," according ...

An X-class solar flare has produced an Earth-directed coronal mass ejection, increasing solar activity and raising the likelihood of geomagnetic impacts within 24 hours.

Sunspot AR3663 erupted with powerful X1.6 and M4 solar flares. NASA's Solar Dynamics Observatory captured the fireworks.

A powerful flare has unleashed a severe solar storm that could cause auroras and satellite disruptions on Earth.

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

By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

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

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

Sparked by a fast-moving solar storm, the Northern Lights may stretch far to the south tonight, and might even be visible ...

Researchers have identified a newly recognized type of extremely energetic particles located in the Sun’s upper atmosphere, revealing a phenomenon that had not been detected before. Solar scientists r ...

Today's solar flare forecasting is pretty straightforward. Earth has several instruments pointed at the sun that monitor it, and when a solar flare erupts, NOAA predicts whether it'll hit Earth and ...
