Solar physicists have long known that the sun stores staggering amounts of magnetic energy, but the exact trigger that lets ...

Forecasters at NOAA's Space Weather Prediction Center monitored a solar flare lasting for hours on Sunday. The Coronal Mass ...

F or all of its life-sustaining energy, the sun is pretty chaotic. Roiling plasma covers its surface along with fluidic snarls of magnetic fields that birth solar flares. These fiery outbursts occur ...

Solar Orbiter captured the most detailed view of a solar flare, observing the build-up of events that lead to the explosion.

The ESA's Solar Orbiter has discovered that solar flares act like avalanches, growing from weak disturbances into powerful ...

NASA explained that the flare was classified as an X1.9 flare. X-class flares are the most powerful type of solar flares. The number 1.9 shows how strong the flare was within this highest category.

The world's largest solar telescope just captured the highest-resolution images of a solar flare to date — and they're spectacular. Researchers trained the Hawaii-based Daniel K. Inouye Solar ...

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 ...

The sun is not a static, tranquil sphere of gas, but an active, turbulent star with magnetic fields that twist and snap in powerful eruptions. Among the most striking and energetic of these eruptions ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. A spot on the sun 10 times larger than Earth has been seen ...

Forecasters at NOAA's Space Weather Prediction Center monitored a solar flare lasting for hours on Sunday. The Coronal Mass Ejection that came with it could produce aurora for northern states and ...
