A giant solar flare on our sun was powered by an avalanche of smaller magnetic disturbances, providing the clearest insight yet into how energy from our star is released in a torrent of high-energy ...

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

Solar flares have an enormous impact on the wider Solar System. These sudden releases of energy can cause geomagnetic storms on Earth and radio blackouts too, like the one that's happened in the last ...

A erupted with M1 and M6 class solar flares. Watch the fireworks in these views from NASA's Solar Dynamics Observatory.

“This is the longest continuous series of images ever created for a single active region: It’s a milestone in solar physics,” ...

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.

People in parts of Canada have been spotting beautiful displays of northern light this week. Our video explains the science ...

A solar storm has once again sparked a brilliant display of colorful auroras Getty The northern lights will be visible again on Tuesday, Sept. 2, due to geomagnetic storms caused by a coronal mass ...

A NOAA forecast has Northern Lights visible in northern U.S. states overnight on Monday, Jan. 19 through Tuesday, Jan. 20, as ...

A week after strong geomagnetic storming gave half the U.S. a chance at seeing the northern lights, new solar activity could bring the aurora to nearly every state. Early Tuesday morning, NOAA’s Space ...

Solar flares can be many times the size of Earth and can damage things like satellites. A new study suggests that eruptions from the sun can be even hotter than researchers thought. Solar flares are ...
