On Saturday, NOAA’s Space Weather Prediction Center (SWPC) noted that an M8.1 solar flare, “an eruption of energy from the sun that generally lasts minutes to hours,” had been detected. Considered ...

A new study led by Southwest Research Institute (SwRI) links quasi-periodic pulsations (QPPs) in solar flares to dynamic oscillations in magnetic reconnection, a phenomenon that can drive space ...

Brace yourselves for a northern light show of potentially epic proportions. Some lucky stargazers in the U.S. may glimpse the aurora borealis after the sun unleashed the second-largest solar flare in ...

The sun has emitted a powerful solar flare that has the capability to interfere with technology on Earth. The explosive burst of radiation peaked on the evening of June 17, matching the intensity of ...

The magic of Christmas could soon manifest in the sky, with northern lights display possible in several U.S. states amid the ...

In the span of two days last week, the sun released two strong solar flares — meaning the solar system experienced its most powerful explosions which can cause some communications blackouts on Earth, ...

A sunspot on the surface of the sun has erupted with a powerful solar flare, triggering radio blackouts across the planet. The X3.3-class flare was flung out from AR3869 in the early hours of October ...

A strong solar flare slightly less powerful than the one that caused May’s dazzling lights is expected to cause intense Northern Lights sightings across several U.S. states over the next few days.

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

Flickering coronal loops in the Sun's outer atmosphere could act as an early warning system for solar flares, according to new research. Reading time 2 minutes Intense solar flares—sudden bursts of ...

Update, Nov. 5, 2025: NOAA has upgraded its forecast to a G3 (strong) geomagnetic storm, meaning up to 21 U.S. states may see aurora overnight on Nov. 6-7, 2025. Two X-class solar flares — the ...
