X2.7-class eruption from sunspot AR4087 disrupts radio signals as the active region rotates toward Earth, raising the risk of more flares ahead.

Solar material from the eruption will likely miss Earth.

It's been one year since the historic Gannon Storm lit up the night sky with auroras and piqued interest in space weather. Here's what experts say we learned from the historic event.

Earth's atmosphere pulses in sync with the sun's fiery outbursts, indicating it is more sensitive to solar activity than previously thought, according to new research.

GOES-19 satellite captures breathtaking footage as a towering solar filament erupts over the sun's eastern limb.

"With only lunar soil and a basic ingredient from the sun — which is always spitting out hydrogen — there's a possibility of creating water."

A powerful new instrument added to the Daniel K. Inouye Solar Telescope promises to maximize the information gleaned from the sun's light.

NASA's PUNCH sun-studying mission has seen first light — and the team says all four instruments are indeed working as expected.

"The next set of solar cycles will be more active."

AI can bridge the growing gap between new and old solar observations and help scientists uncover overlooked aspects of our star's long-term evolution, a new study argues.
